A second mate (2nd mate) or second officer (2/O) is a licensed member of the deck department of a merchant ship holding a Second Mates Certificate of Competence,[1] by an authorised governing state of the International Maritime Organization (IMO). The second mate is the third in command (or on some ocean liners fourth) and a watchkeeping officer, customarily the ship's navigator. Other duties vary, but the second mate is often the medical officer[2] and in charge of maintaining distress signaling equipment. On oil tankers, the second mate usually assists the chief mate with the cargo operations.

The navigator's role focuses on creating the ship's passage plans. A passage plan is a comprehensive, step by step description of how the voyage is to proceed from berth to berth or one port to another. The plan includes undocking, departure, the en route portion of a voyage, approach, and mooring at the destination.

The GMDSS (Global Maritime Distress and Safety System) officer role consists of performing tests and maintenance, and ensuring the proper log-keeping on the ship's Global Maritime Distress Safety System equipment. Safety equipment includes emergency position-indicating radio beacons, a NAVTEX unit, INMARSAT consoles, various radios, search and rescue transponders, and digital selective calling systems.

Watchkeeping

[edit]

A second mate is almost always a watchkeeper.[3][failed verification] In port and at sea, the second mate is responsible to the captain for keeping the ship, its crew, and its cargo safe for eight hours each day. Traditionally, the second mate stands a "12-4" watch: from midnight until 4 a.m. and noon until 4 p.m. On watch, he must enforce all applicable regulations, such as safety of life at sea and pollution regulations. In port, the watch focuses on duties such as cargo operations, fire and security watches, monitoring communications, and the anchor or mooring lines.

International Maritime Organization (IMO) regulations require the officer be fluent in English. This is required for a number of reasons, such as to use charts and nautical publications, understand weather and safety messages, communication with other ships and coast stations, and to be able to work with a multi-lingual crew.

Sea watch

[edit]

At sea, the mate on watch has three fundamental duties: to navigate the ship, to safely avoid traffic, and to respond to emergencies. Mates generally stand watch with able seamen who act as helmsman and lookout. The helmsman executes turns and the lookout reports dangers such as approaching ships. These roles are often combined to a single helmsman/lookout and, under some circumstances, can be eliminated completely.[4] The ability to smartly handle a ship is key to safe watchstanding. A ship's draught, trim, speed and under-keel clearance all affect its turning radius and stopping distance. Other factors include the effects of wind and current, squat, shallow water, and similar effects. Shiphandling is key when the need arises to rescue a man overboard, to anchor, or to moor the ship.

The officer must also be able to transmit and receive signals by Morse light and to use the International Code of Signals.

Officer in charge of navigational equipment and other aids to navigation

[edit]

On the ship the second officer is the officer that works under the master, i.e. the captain of the ship, and shoulders the responsibility of checking the functionality of all the navigational equipment, such as the echo-sounder, radar, ECDIS, AIS, and on some vessels even the GMDSS radio equipment; however, recently it has been observed that companies tend to designate the responsibility of maintaining the GMDSS equipment to the third officer. These checks are made in according to the companies' planned maintenance system. In addition, these checks are usually made prior to arrival and departure ports. Often if any navigational equipment is suspected of being faulty then it should be checked that the equipment is in working order as per the given performance standards. Correction of navigation charts and the duties of keeping the charts up to date rests on the second mate.[citation needed]

[edit]
Further information: Navigation
While a ship is under way, the officers navigate it, typically in three shifts or watches.

Celestial, terrestrial, electronic, and coastal navigation techniques are used to fix a ship's position on a navigational chart. Accounting for effects of winds, tides, currents and estimated speed, the officer directs the helmsman to keep to track. The officer uses supplemental information from nautical publications, such as sailing directions, tide tables, notices to mariners, and radio navigational warnings to keep the ship clear of danger in transit.

Safety demands the mate be able to quickly solve steering control problems and to calibrate the system for optimum performance. Since magnetic and gyrocompasses show the course to steer, the officer must be able to determine and correct for compass errors.

Weather's profound effect on ships requires the officer be able to interpret and apply meteorological information from all available sources. This requires expertise in weather systems, reporting procedures, and recording systems.

Traffic management

[edit]
Mates were in high demand during World War II.

The International Regulations for Preventing Collisions at Sea are a cornerstone of safe watchkeeping. Safety requires that one live these rules and follow the principles of safe watchkeeping. Maximizing bridge teamwork, including bridge resource management is an emerging focus in watchkeeping.

The main purpose for radar and automatic radar plotting aid (ARPA) on a ship's bridge are to move safely among other vessels. These tools help to accurately judge information about prominent objects in the vicinity, such as

  • range, bearing, course and speed;
  • time and distance of closest point of approach; and
  • course and speed changes.

These factors help the officer apply the COLREGS to safely maneuver in the vicinity of obstructions and other ships.

Unfortunately, radar has a number of limitations, and ARPA inherits those limitations and adds a number of its own. Factors such as rain, high seas, and dense clouds can prevent radar from detecting other vessels. Conditions such as dense traffic and course and speed changes can confuse ARPA units. Finally, human errors such as inaccurate speed inputs and confusion between true and relative vectors add to the limitations of the radar/ARPA suite.

The radar operator must be able to optimize system settings and detect divergences between an ARPA system and reality. Information obtained from radar and ARPA has to be treated with scrutiny: over reliance on these systems has sunk ships. The officer must understand system performance. Examples include limitations and accuracy, tracking capabilities and limitations, and processing delays, and the use of operational warnings and system tests.

Emergencies

[edit]

Emergencies can happen at any time, and the officer must be equipped to safeguard passengers and crew. After a collision or a grounding, the officer must be able to take initial action, perform damage assessment and control, and understand the procedures for rescuing persons from the sea, assisting ships in distress, and responding to any emergency which may arise in port.

The officer must understand distress signals and know the IMO Merchant Ship Search and Rescue Manual.

Cargo handling

[edit]

The ship's officer must be able to oversee the loading, stowage, securing and unloading of cargoes. Requirements include understanding the care of cargo during the voyage.

Of particular importance is knowledge of the effect of cargo including heavy lifts on the seaworthiness and stability of the ship. The officer must also understand safe handling, stowage and securing of cargoes, including cargoes that are dangerous, hazardous or harmful.

Controlling ship operations

[edit]

The officer has special responsibilities to keep the ship, the people on board and the environment safe. This includes keeping the ship seaworthy during fire and loss of stability, and providing aid and maintaining safety during man overboard, abandoning ship, and medical emergencies.

Understanding ship's stability, trim, stress, and the basics of ship's construction is a key to keeping a ship seaworthy. Competencies include knowing what to do in cases of flooding and loss of buoyancy. Fire is also a constant concern. Knowing the classes and chemistry of fire, fire-fighting appliances, and systems prepares the officer to act fast in case of fire.

An officer must be expert in the use of survival craft and rescue boats, their launching appliances and arrangements, and their equipment including radio life-saving appliances, satellite EPIRBs, SARTs, immersion suits and thermal protective aids. It's important to be expert in the techniques for survival at sea techniques in case it's necessary to abandon ship.

Officers are trained to perform medical tasks and to follow instructions given by radio or obtained from guides. This training includes what to do in case of common shipboard accidents and illnesses.

Licensing

[edit]

United Kingdom

[edit]

It is usual for a second officer to hold a chief officer's certificate. Since the first half of the 20th century, the usual terminology in the British Merchant Navy has been "second officer" rather than "second mate", although "second mate" may be used colloquially.

United States

[edit]
A second mate must have a number of qualifications, including a license.

To become a second mate (unlimited) in the United States, one must have been a third mate and have at least 360 days of service while holding that license. Third mates who attained their licenses after the implementation of STCW 95 have passed all the examination topics required for the second mate's license, and can automatically claim the second mate's license after documenting the required service. Third mates who attained their licenses before STCW 95 must meet additional requirements.

There are two methods to attain an unlimited third mate's license in the United States: to attend a specialized training institution, or to accumulate "sea time" and take a series of training classes and examinations.[5]

Training institutions that can lead to a third mate's license include the U.S. Merchant Marine Academy (deck curriculum), the U.S. Coast Guard Academy, and U.S. Naval Academy with qualification as an under way officer in charge of a navigational watch, any of the state maritime colleges, the Great Lakes Maritime Academy, or a three-year apprentice mate training program approved by the commandant of the U.S. Coast Guard.

A seaman may start the process of attaining a license after three years of service in the deck department on ocean steam or motor vessels, at least six months of which as able seaman, boatswain, or quartermaster. Then the seaman takes required training courses, and completes on-board assessments. Finally, the mariner can apply to the United States Coast Guard for a third mate's license.

A master of 1,600-ton vessels can, under certain circumstances, begin the application process for an unlimited third mate's license.

If approved the applicant must then successfully pass a comprehensive license examination before being issued the license. Hawsepiper is an informal maritime industry term used to refer to an officer who began his or her career as an unlicensed merchant seaman and did not attend a traditional maritime college/academy to earn the officer license. A ship's hawsepipe is the pipe passing through the bow section of a ship that the anchor chain passes through. Hawsepiper refers to climbing up the hawsepipe, a nautical metaphor for climbing up the ship's rank structure. Hawsepiper is considered a positive term when said respectfully. Most hawsepipers are proud of their background and use the term to describe themselves.

Several merchant seamen's unions offer their membership the required training to help them advance. Similarly, some employers offer financial assistance to pay for employee training. Otherwise, the mariner is responsible for the cost of the required training.

There have been complaints that the hawsepiper progression path has been made too difficult since the requirements of STCW 95 have been enacted. Issues include the cost in time and money to meet formal classroom training requirements. Critics assert that the newer requirements will eventually lead to a shortage of qualified mariners, especially in places like the United States.

India

[edit]

In India the authority to issue licences rests with the Directorate General of Shipping. To be eligible to receive such a licence a cadet must have worked for the required amount of time and have work experience which should translate into the required amount of seatime prescribed by the administration in accordance with the STCW Code 2010. In addition, he must possess various mandatory training in life saving, survival, fire fighting, and bridge team management, among others. Lastly, he must have cleared the 2MFG written and orals conducted by the various Mercantile Marine Departments, aka MMD. The for the 2MFG orals a candidate may be examined by a nautical surveyor, deputy nautical advisers or the nautical adviser of India.

The Age of Sail

[edit]

In the 1840s personal narrative Two Years Before the Mast, the author (Richard Henry Dana Jr.) describes the role of a second mate on an American merchant trading brig as follows:

The role of the second mate officer (or any subordinate officer) was then very much determined by the captain of a ship. Hence, as the author has described, it is not necessarily the case with the officer in other ships. Nowadays, the role of a second officer on board any ship is that of a navigating officer; he is in charge of navigation, navigational equipment and navigational publications. He reports to the captain of the ship. Deck work charge is not expected on a second officer but he may do so. He is a licensed officer.

Overview and historical context

Definition and primary responsibilities

The second mate, also known as the second officer, is a licensed deck officer in the merchant navy's deck department, positioned as the third-in-command after the master and chief mate, with primary accountability for navigational watchkeeping and related operational support. This role requires certification as an officer in charge of a navigational watch (OICNW) on ships of 500 gross tonnage or more, as defined under the International Convention on Standards of Training, Certification and Watchkeeping for Seafarers (STCW), ensuring the holder meets minimum competency standards for safe vessel operation. Primary responsibilities encompass assisting the master and in supervising overall ship operations, including route , monitoring, and of navigational publications, charts, and systems such as radios, lifeboats, and . The second mate also directs deck in routine tasks, ensures adherence to international maritime and pollution prevention regulations, and often manages the ship's supplies and procedures as the designated . These duties emphasize and across voyages. Within the deck department hierarchy, the second mate reports directly to the chief mate for daily oversight and to the master for ultimate command, while supervising subordinate personnel including the third mate, able seamen, ordinary seamen, and deck cadets to coordinate deck activities effectively. Essential skills for the second mate include robust leadership to guide and motivate deck teams, advanced technical proficiency in navigation principles and equipment operation, and vigilant oversight of safety and compliance protocols to prevent incidents at sea. In contemporary shipping, the second mate's role is integral to diverse merchant vessel types, such as container ships for global trade routes, tankers for liquid cargo transport, and bulk carriers for dry commodities, where responsibilities adapt to vessel-specific demands like cargo stability and route complexity.

Evolution from Age of Sail to modern era

During the Age of Sail in the 18th and 19th centuries, the second mate served as a navigation officer on wooden merchant and naval sailing ships, relying on celestial navigation techniques with instruments such as the sextant and chronometer to plot courses and determine latitude and longitude during long voyages. This officer also oversaw sail management, directing crew in the maintenance, trimming, and repair of rigging on key masts like the main and mizzen to optimize vessel performance under varying wind conditions. As a junior officer, the second mate stood regular watches, enforced discipline among the crew, supervised daily tasks such as provisioning and deck maintenance, and supported emergency operations, setting the role apart from the first mate's emphasis on overall command and cargo oversight or the third mate's more entry-level assignments in seamanship and safety. The shift to and iron hulls in the mid-to-late marked a pivotal transition for mate, reducing reliance on handling while expanding coordination with emerging engine rooms to integrate mechanical power with traditional . Iron enabled larger, more vessels suited to , prompting second mates to adapt by focusing on course plotting amid new hydrodynamic challenges and early mechanical systems, though celestial methods remained central until electronic aids emerged. By the early , the introduction of radio direction-finding in the early began supplementing visual and celestial techniques, allowing second mates to home in on shore signals for improved positional accuracy during coastal approaches. The 20th century brought further modernization to the second mate's role through technological and regulatory advancements. The 1912 sinking of the RMS Titanic underscored the position's critical involvement in safety protocols, as Second Officer Charles Lightoller supervised lifeboat loading and evacuation amid inadequate drills, contributing to over 1,500 deaths and prompting the first International Convention for the Safety of Life at Sea (SOLAS) in 1914 to standardize emergency procedures. World War II intensified training demands, with the U.S. Merchant Marine Cadet Corps—established in 1938 and formalized at the Kings Point Academy in 1943—preparing second mates for high-risk navigation across convoy routes threatened by submarines and aircraft, where they managed radar prototypes and convoy formations to sustain Allied supply lines. Post-war efforts by the International Maritime Organization (IMO), including the 1974 SOLAS Convention and its 1978 amendments, formalized the second mate's duties in watchkeeping, collision avoidance, and life-saving drills, reflecting a global push for uniform officer competencies amid radio and early radar integration. These evolutions built a foundation for the modern second mate's emphasis on integrated bridge operations and safety oversight.

Deck department duties

Watchkeeping and navigation

The second mate, as the officer in charge of a navigational watch (OICNW) under the , typically follows a consisting of 4-hour shifts within a 24-hour cycle, divided among the deck officers to continuous oversight of the bridge and safe passage of the vessel. This traditional "4-on, 8-off" rotation aligns with STCW rest requirements, mandating a minimum of 10 hours of rest in any 24-hour period, which may be divided into no more than two periods one of which shall be at least 6 hours long, and 77 hours of rest in any 7-day period; exceptions allow reduction to not less than 6 consecutive hours of rest in any 24-hour period for no more than two consecutive days, provided at least 70 hours of rest in any 7-day period, with schedules posted where clearly displayed to compliance and prevent fatigue-related errors. In navigation responsibilities, the second mate plots courses and monitors the vessel's position using electronic systems such as the Electronic Chart Display and Information System (ECDIS), (GPS), and , ensuring accurate fixes at regular intervals to maintain the planned track. These tools enable real-time route monitoring and adjustments for deviations caused by currents, , or , with the second mate verifying positions through cross-referencing multiple sources to uphold navigational . The second mate maintains and operates key aids to , including gyrocompasses for directional , sounders for depth to avoid shallow waters, and the Automatic Identification (AIS) for tracking nearby vessels and the ship's position. Routine these systems function correctly, with gyrocompasses calibrated for accuracy and sounders calibrated against known depths, while AIS is integrated with overlays for situational awareness. For traffic management, the second mate applies the International Regulations for Preventing Collisions at Sea (COLREGS) to assess collision risks and execute rule-based maneuvers, such as altering course or speed early to maintain a safe passing distance. This involves using radar and ARPA (Automatic Radar Plotting Aids) to plot relative motions of other vessels, prioritizing actions like giving way in crossing or overtaking situations to comply with COLREGS rules 13–17. Daily routines for the second mate include updating nautical charts and publications with the latest notices to mariners, monitoring weather via meteorological instruments and forecasts to anticipate changes, and assisting in voyage planning by appraising routes for hazards and optimizing fuel efficiency. These tasks ensure the passage plan—covering appraisal, planning, execution, and monitoring—remains current, with weather routing integrated to select optimal paths avoiding adverse conditions. In emergencies during watches, the second mate initiates procedures like sounding alarms and notifying the master, as detailed in dedicated safety protocols.

Cargo handling and operations

The second mate, as an officer in charge of a navigational watch () under the , plays a key supervisory in handling and operations, ensuring compliance with international standards for safety and efficiency. This involves overseeing the loading, stowage, securing, and unloading of to maintain vessel stability and prevent damage, often while standing watch in . These duties are outlined in the , which specifies competencies for assessing impacts on seaworthiness and executing operations according to plans. In cargo supervision, the second mate plans and verifies stowage to optimize vessel stability, using cargo plans that detail weight distribution, lashing requirements, and securing methods to avoid shifting during transit. This includes calculating trim and list to ensure the ship's center of gravity remains within safe limits, drawing on stability booklets and stress tables provided by the vessel's classification society. For instance, on container vessels, the second mate ensures even bay-by-bay loading to prevent excessive list, coordinating adjustments with the chief mate if deviations occur. Compliance with regulations like the International Convention for Safe Containers (CSC) is mandatory to verify container integrity before stowage. Loading and unloading procedures are coordinated by the second mate with stevedores and terminal personnel, supervising the use of cranes, booms, and other gear to handle cargo safely. This entails inspecting equipment for defects prior to operations and directing deck crew to secure slings, nets, and bridles, as required under STCW competencies for cargo handling. For hazardous cargoes, the second mate enforces the International Maritime Dangerous Goods (IMDG) Code, verifying proper labeling, segregation, and ventilation to mitigate risks during transfer. Communication via ship-shore checklists ensures synchronized operations, with the second mate halting activities if safety protocols are breached. The second mate contributes to documentation by preparing and updating cargo manifests that consolidate bills of lading details, recording weights, positions, and conditions to support customs clearance and stability calculations. Stability booklets are reviewed and annotated during operations to log changes in loading, ensuring post-operation verification aligns with the approved cargo plan. These records, maintained in accordance with SOLAS Chapter VI, provide a verifiable audit trail for port state control inspections. Handling diverse cargo types falls under the second mate's oversight, with specifics tailored to maintain trim and list control. For dry bulk cargoes like grain or coal, the second mate supervises trimming to achieve even distribution and prevent free surface effects that could compromise stability, per the IMSBC Code guidelines. On container ships, focus shifts to vertical and horizontal weight balancing across stacks, using twistlocks and lashing bridges to secure units against rolling motions. For non-tanker liquid cargoes, such as chemicals in drums or intermediate bulk containers, the second mate ensures upright stowage and spill containment, avoiding incompatible pairings as per IMDG provisions. These practices prioritize conceptual stability principles over exhaustive metrics, emphasizing real-time adjustments based on draft surveys. During port operations, the second mate manages deck crew for berthing and unberthing, integrating cargo activities with mooring lines and gangway security to facilitate seamless transitions. This includes briefing crew on weather impacts and equipment readiness, ensuring all hands contribute to lashing completion before departure, as per standard watchkeeping protocols in port.

Safety, emergencies, and ship control

The second mate is integral to the vessel's safety regime, overseeing the conduct of essential drills such as fire-fighting, abandon ship, and man-overboard exercises to ensure crew proficiency and preparedness. These drills must be conducted in accordance with SOLAS Chapter III, Regulation 19, which requires, for cargo ships, at least one fire drill and one abandon ship drill every month; different types of emergency drills at least every three months; and onboard training and instructions provided to crew at least every three months. The second mate verifies crew participation and logs outcomes to demonstrate compliance during port state inspections. Additionally, they maintain life-saving appliances (LSAs), including lifeboats, liferafts, and personal flotation devices, through routine inspections and servicing as outlined in SOLAS Chapter III, Regulation 20, ensuring equipment readiness via weekly visual checks, monthly functional tests, and annual thorough examinations by certified providers. In emergency situations, the second mate, often serving as the officer of the watch, assumes immediate responsibility for coordinating responses to incidents like grounding, collision, or flooding, initiating damage control protocols such as watertight door closures and counter-flooding to preserve stability. This includes directing crew to muster stations, communicating with the master and bridge team, and executing contingency plans from the ship's emergency response manual, in line with STCW Code Table A-II/1 competencies for maintaining shipboard safety and responding to navigational hazards. Their role emphasizes rapid assessment and mobilization to minimize risks to personnel and the environment, with navigation during such crises drawing on established watchkeeping principles to maneuver the vessel away from further peril. For broader ship control, the second mate monitors engine room orders relayed to the bridge, ensuring seamless execution of speed and course adjustments while overseeing ballast operations to optimize trim, stability, and seaworthiness as per IMO intact stability criteria. They also enforce environmental compliance under MARPOL Annex I and V, tracking oil and garbage discharge logs to prevent pollution and reporting any non-conformities. In risk management, the second mate supports the International Safety Management (ISM) Code by implementing the ship's safety management system (SMS), conducting internal audits of safety procedures, and documenting near-misses or incidents for corrective action, thereby fostering a proactive culture of hazard identification and mitigation. The second mate further coordinates with the department to uphold vessel , reviewing inspections of hull structures, systems, and auxiliary to address potential failures that could or operations. This ensures alignment between deck and activities, such as during transfers or repairs, contributing to overall regulatory adherence under SOLAS and ISM frameworks.

Licensing and

International and regulatory framework

The International Convention on Standards of Training, Certification and Watchkeeping for Seafarers (STCW), adopted by the (IMO) in 1978 and entering into force in , established the first global minimum requirements for the , , and watchkeeping of seafarers, including deck officers like the second mate. This convention addressed inconsistencies in national standards that had previously led to safety risks in international shipping, mandating competencies in areas such as , operations, and response to ensure uniform professional qualifications. The STCW Code, an integral part of the convention, details these standards through tables of competence, with Table A-II/1 specifically outlining the knowledge, understanding, and proficiencies required at the operational level for officers in charge of a navigational watch (OICNW). The 2010 Manila Amendments, adopted at an IMO diplomatic conference and entering into force on January 1, 2012, significantly revised the STCW to incorporate advancements in maritime technology and operations, emphasizing enhanced proficiency in navigation (including electronic chart display and information systems, or ECDIS), cargo handling, and safety management for OICNW roles. These amendments require second mates, as OICNW, to demonstrate operational-level competencies under STCW Regulation II/1, such as planning and executing safe passages, maintaining watchstanding standards, and responding to emergencies on vessels of 500 gross tonnage or more, with endorsements specifying limitations by tonnage and operational area (e.g., unlimited, near-coastal). The IMO, as the custodian of STCW, plays a central role in defining these competencies, regularly reviewing and updating the code through its Maritime Safety Committee to align with evolving industry needs like leadership and team resource management. To facilitate global mobility, the promotes through mutual recognition of certificates issued by its 165 contracting states (), allowing to accept foreign STCW endorsements for OICNW without re-examination, provided the issuing administration complies with convention standards. The IMO maintains a public database of recognized certificates and oversees standards via audits, ensuring reciprocity while permitting bilateral agreements for specific endorsements. As of 2025, amendments to the STCW Code adopted in May 2024 at IMO's Maritime (MSC 108) introduce mandatory on the prevention of and response to and (including , , and ) for seafarers, added to Table A-VI/1-4 of the STCW Code and entering into force on 1 January 2026. These updates require awareness of causes, consequences, intervention, reporting, and trauma-informed support, applicable to all seafarers including deck officers. Additionally, as of 1 January 2025, IMO Resolution MSC.519(106) mandates electronic issuance of STCW certificates and endorsements to improve verification and administration. National implementations of these international standards vary, with details covered in jurisdiction-specific requirements.

Requirements in the United Kingdom

In the United Kingdom, the (MCA) administers the Deck Officer Certificate of Competency (CoC) at the second mate level, equivalent to the unlimited under STCW II/2, enabling officers to serve as in the deck department on vessels of unlimited . This aligns with international STCW standards but operates independently of EU directives following , as established by the Shipping (Standards of , and for ) Regulations 2022. To qualify, candidates must hold a valid of the Watch (OOW) unlimited CoC (STCW II/1) and complete at least 12 months of service as an OOW on vessels of 500 or more, documented in an MCA-approved Training Record Book. Additional prerequisites include approved courses such as Aids and Simulator (NAEST) Operational level, Element and (HELM) at management level, and safety including Advanced Fighting, Proficiency in and Boats, and Medical First Aid, all completed within the preceding five years at MCA-recognized providers. Candidates must also pass SQA-written examinations in and Ship Stability and Operations, followed by an MCA oral and practical examination covering , stability, meteorology, cargo operations, and emergency procedures. Upon successful completion, the CoC is valid for unlimited tonnage and worldwide trading areas, subject to endorsements for radiocommunications and other functions, provided a valid Global Maritime Distress and Safety System (GMDSS) General Operator's Certificate (GOC) is held. The certificate is issued for five years and requires revalidation through demonstrated sea service—such as 12 months in the last five years on vessels over 80 gross tonnage—combined with refresher training in core safety areas and synchronization of the GMDSS certificate, including any necessary GMDSS refresher if expired. Applications for issuance or revalidation are submitted via form MSF 4274 to the MCA, with a valid medical certificate (ENG1 or equivalent) mandatory at all stages.

Requirements in the United States

In the United States, the United States Coast Guard (USCG) regulates the certification of second mates through the Merchant Mariner Credential (MMC) program, aligning with the International Convention on Standards of Training, Certification and Watchkeeping for Seafarers (STCW). The entry-level deck officer endorsement is as Third Mate (Officer in Charge of a Navigational Watch, or OICNW), from which mariners progress to Second Mate. To qualify for the Second Mate endorsement on ocean or near-coastal self-propelled vessels of unlimited tonnage, applicants must hold a valid Third Mate endorsement and complete at least 360 days of deck service as OICNW, with all service on vessels of 100 gross register tons (GRT) or more and at least 180 days on vessels of 1,600 GRT or more. For the initial Third Mate endorsement, applicants must pass USCG-administered examinations covering key competencies, including written tests on the International Regulations for Preventing Collisions at Sea (rules of the road), ship handling, cargo operations, navigation safety regulations, and emergency procedures. Upgrading to Second Mate from Third Mate typically requires no additional examinations if the sea service criteria are met, though practical assessments may be incorporated during STCW proficiency evaluations. Second Mate endorsements specify operational limits, including (unlimited from shore), near-coastal ( 200 nautical miles), or inland waters, with starting from 100 GRT based on service ; unlimited is granted when service calculations exceed 10,000 GRT equivalent. Applicants must also hold a valid (TWIC), , and pass drug testing. Training mandates for Second Mates follow STCW Code Section A-II/1 for OICNW, requiring USCG-approved courses in basic firefighting (including prevention and advanced techniques), proficiency in survival craft and rescue boats (other than fast rescue boats), and medical first aid or medical care on board ship. These must be completed prior to endorsement issuance or renewal, with refreshers every five years. USCG requires approved training for deck officers serving on ships operating in polar waters to ensure compliance with the International Code for Ships Operating in Polar Waters (Polar Code), including basic operations courses covering ice navigation, environmental risks, and ship maneuvering in polar conditions, as implemented through relevant NVICs such as NVIC 01-17 and STCW standards.

Requirements in other jurisdictions

In India, the (DG Shipping) oversees the issuance of the Second Mate (Foreign Going) Certificate of Competency, which qualifies officers to serve as Officer in Charge of a Navigational Watch (OICNW) on vessels of 500 or more. Candidates must complete at least 18 months of approved sea service, including a minimum of 6 months of duties, following a Diploma in Nautical Science or equivalent pre-sea training, and pass written, oral, and practical competency examinations aligned with STCW standards. Australia's Australian Maritime Safety Authority (AMSA) requires similar STCW-compliant qualifications for the OICNW certificate, emphasizing 12 months of sea service with at least 6 months as an understudy to the officer of the watch, alongside approved training courses focused on regional navigation challenges in Asia-Pacific routes. In Singapore, the Maritime and Port Authority (MPA) issues the Class 2 Deck Officer Certificate of Competency after candidates complete 12 months of sea service post-cadetship, pass written examinations, and demonstrate proficiency through simulator-based assessments and orals, with particular stress on advanced electronic navigation systems suited to high-traffic port operations. Variations exist across other jurisdictions; for instance, the Philippines' Maritime Industry Authority (MARINA) allows shorter sea service of 12 months for OICNW certification under certain pathways, reflecting efficiencies in flag state training programs common in Asian registries. European Union states impose stricter language proficiency mandates beyond STCW's baseline English requirements, often necessitating certification in the national language for operational commands on flagged vessels, as seen in France where officers must demonstrate French language competency for safety-critical roles. A key challenge in multinational hiring is the equivalency of certificates, where discrepancies in service validation, modules, and endorsements between states can delay recognition and lead to barriers, particularly for officers from developing nations seeking roles on international fleets. As of 2025, developing maritime nations like and the are increasingly adopting digital simulation , including VR/AR platforms for bridge and scenarios, to bridge resource gaps and enhance STCW compliance without extensive physical time.

Career progression and training

Entry paths and qualifications

Individuals typically enter the role of second mate through structured educational programs at maritime academies or via company-sponsored cadetships, which combine theoretical with practical . A common pathway involves enrolling in a four-year in or maritime transportation at accredited institutions, such as the or Texas A&M University at Galveston, where students complete classroom instruction in navigation, seamanship, and maritime law alongside mandatory voyages. Upon graduation, cadets often qualify for an initial third mate license after fulfilling embedded service requirements, setting the foundation for advancement to second mate. Alternatively, sponsored cadetships offered by shipping companies provide hands-on from the outset, where candidates join vessels as deck cadets while attending periodic shore-based courses, typically lasting 18 to 36 months to achieve basic officer certification. The progression from entry-level ratings to second mate emphasizes building practical skills through incremental qualifications. Aspiring officers often start as ordinary seamen, performing basic deck duties, and advance to after completing and exams, which require at least 12 months of service in the (or 18 months without approved ). From there, individuals pursue via approved programs, involving additional time and competency assessments in and operations. To qualify for second mate, candidates must then accumulate further as third mates, demonstrating proficiency in and . Sea service is a cornerstone of eligibility, with most jurisdictions mandating a minimum of 12 to 18 months of service on vessels of appropriate before attempting second mate examinations. For instance, under U.S. standards, applicants need 360 days of service as officer in charge of a navigational watch on appropriate vessels while holding a Third Mate endorsement, with at least 90 days recency within the prior seven years (as of 2025). This service must occur on self-propelled vessels over 100 gross registered tons, ensuring candidates gain exposure to real-world operational challenges. Alternative entry routes include transitions from military service, where veterans leverage prior sea duty through programs like the U.S. Department of Transportation's to Mariner initiative, which credits naval experience toward civilian licensing requirements and facilitates direct entry into . programs, such as apprenticeships at institutions like the Maritime and Studies (MITAGS), allow non-traditional candidates to initial rating roles by combining accelerated coursework with supervised sea time, often leading to status in under two years. Global variations in entry paths reflect economic and industry structures, with sponsored programs prevalent in countries like and the , where shipping firms such as Anglo-Eastern or Magsaysay Maritime cover costs in exchange for post-graduation contracts, enabling low-barrier access for local talent. In contrast, European pathways, such as those in the UK through the Board, often require self-funding for tuition or partial apprenticeships, though subsidies may offset costs for EU nationals pursuing deck qualifications. These differences influence , with sponsored models in facilitating higher volumes of entrants to meet global crewing demands.

Ongoing professional development

Second mates, as officers in charge of a navigational watch, are required to complete mandatory refresher training under the Standards of Training, Certification and Watchkeeping for Seafarers (STCW) Convention to maintain their competencies throughout their careers. This includes renewing basic safety training every five years, which encompasses personal survival techniques, fire prevention and firefighting, elementary first aid, and personal and social responsibilities. Additionally, advanced firefighting training must be refreshed every five years through approved courses that cover organization of fire-fighting parties, fire-fighting techniques, and control of fire-fighting operations aboard ships. Beyond basic refreshers, second mates pursue specialized courses to enhance navigational and leadership skills. Electronic Chart Display and Information System (ECDIS) revalidation is essential, typically required every three years or as part of STCW revalidation to ensure proficiency in electronic navigation, including system limitations and voyage planning. Bridge resource management (BRM) training, mandated under STCW for operational-level officers, focuses on effective teamwork, communication, and decision-making on the bridge, often incorporating simulator-based exercises. Leadership simulations are integrated into these programs to develop managerial skills for handling complex scenarios, such as collision avoidance or emergency responses. Career progression for second mates involves obtaining endorsements to qualify for larger vessels or specialized trades. Under STCW Regulation II/1, officers can upgrade to endorsements for unlimited tonnage after meeting sea service requirements and completing advanced training, enabling service on ocean-going ships beyond initial limitations. For specialized trades like liquefied natural gas (LNG) carriers, additional endorsements per STCW Chapter V/1-2 require training in the handling of liquefied gases, including cargo operations, safety measures, and environmental protection. In 2025, ongoing for second mates increasingly emphasizes industry trends toward and technological integration. on low-carbon fuels, such as LNG and biofuels, addresses the maritime sector's decarbonization goals, focusing on handling, engine operations, and emission compliance amid evolving regulations like the IMO's strategy. AI-assisted is also gaining prominence, with courses covering AI tools for route optimization, collision , and autonomous systems to improve efficiency and on the bridge. Membership in professional bodies supports continuous development. The Nautical Institute offers a voluntary Continuing Professional Development (CPD) scheme for deck officers, including second mates, where members log activities like courses, seminars, and sea service to earn credits, fostering lifelong learning and career advancement.

Role in multinational crews

In modern merchant shipping, crews on vessels are typically composed of personnel from multiple nationalities, reflecting the global nature of the industry. Officers, including second mates, are often drawn from European countries such as the United Kingdom, Norway, or Poland, while ratings and junior crew members frequently hail from Asian nations like the Philippines, India, or Indonesia, which supply a significant portion of the global seafaring workforce—estimated at over 1.5 million seafarers, with Filipinos comprising about 25-30% of officers and ratings combined. This multinational composition arises from economic factors, including lower labor costs in developing countries and the use of flags of convenience, which allow shipowners to hire from diverse pools without nationality restrictions beyond minimum safe manning requirements. As the ship's navigator and a key watchkeeping officer, the second mate plays a pivotal role in integrating these diverse team members during navigation duties and bridge operations. The second mate faces unique leadership challenges in such crews, particularly in bridging language barriers that can hinder clear instructions during critical tasks like course adjustments or emergency drills. Cultural differences may lead to varying interpretations of authority or teamwork norms—for instance, hierarchical expectations in some Asian cultures contrasting with more egalitarian approaches in European ones—potentially escalating to conflicts that affect morale and operational efficiency. Enforcing uniform safety standards, such as those under the International Safety Management (ISM) Code, becomes complex when crew members from different backgrounds prioritize protocols differently, requiring the second mate to mediate while maintaining vigilance over navigation and watchkeeping. To address these, the second mate relies on standardized communication tools, including the International Maritime Organization's (IMO) Standard Marine Communication Phrases (SMCP), which provide a simplified English framework for essential exchanges, supplemented by digital apps for logging shift handovers and real-time updates to minimize misunderstandings. Legally, the second mate must apply the flag state's laws—governed by conventions like the United Nations Convention on the Law of the Sea (UNCLOS)—which dictate vessel operations, safety, and labor standards, while respecting the rights of crew members from various nationalities under the Maritime Labour Convention (MLC) 2006. This dual obligation can involve ensuring compliance with flag state inspections alongside accommodating crew-specific needs, such as repatriation rights or cultural accommodations, to prevent disputes that could impact ship performance. Despite these hurdles, multinational crews offer benefits like diverse skill sets that enhance problem-solving in global routes and foster broader cultural perspectives among officers. However, issues persist, including increased fatigue from round-the-clock operations in mixed teams, where miscommunications may prolong tasks and exacerbate exhaustion during long voyages.
