Mammoet was founded on the 13th of May 1807 in Utrecht, the Netherlands, when Dutch entrepreneur Jan Goedkoop founded a maritime company with the purchase of a 140-tonne cargo vessel. The company, called 'Gebroeders Goedkoop' (‘Goedkoop Brothers’), offered both maritime cargo and passenger transport. In 1862, the company acquired its first tugboat, and from 1920 onwards, the company focused on tug and salvage services.

In 1971, Goedkoop merged with Van Wezel from Hengelo (Netherlands): a company that specialized in heavy transport and cranes. The new company was called Mammoet Transport. In 1972, another company was acquired, Stoof Breda, which at that time was one of the market leaders in engineered heavy lifting and transport in the Netherlands.

In 1973, Mammoet Transport became a subsidiary of Koninklijke Nederlandse Stoomboot-Maatschappij (KNSM) located in Amsterdam. At the same time, the company name was changed to Mammoet. In 1973, Mammoet Shipping was founded.

In 1981, KNSM and Mammoet became part of Nedlloyd Group. In 2000, Mammoet was acquired by, and merged with, Van Seumeren Kraanbedrijf, a company that had been founded in 1966. In 2001, Mammoet sold its maritime branch Mammoet Shipping to shipping company Spliethoff Group [nl], and was rebranded to BigLift Shipping [nl].

In 2020, Mammoet merged with UK-based engineered heavy-lifting company ALE, forming the largest engineered heavy-lifting and transport company in the world.[3]

On 14 March 2023, parent company SHV holdings decided to put Mammoet up for sale. SHV CEO Jeroen Drost suggested that Mammoet required huge investments in the future, and it was not in the best interest of SHV.[4] On 22 March 2023, Mammoet received permission from the Russian government to sell its Russian subsidiary to Chinese Conglomerate Tianjin co Ltd. Following the start of the latest phase of the Russo-Ukrainian War in 2022, SHV stopped all its new operations and investments.[5]

Mammoet has been involved in several high-profile projects, including the transportation of a 600-tonne tunnel boring machine in London. The company also played a key role in the construction of the world's largest offshore wind farm, the London Array. Also, in 2024, Mammoet transported, lifted, and positioned the Oder railway bridge on the German-Polish border.[6]

The company is active in the petrochemical industry, the mining and metals industry, civil construction and the energy sector - such as nuclear power, conventional power, offshore, and onshore wind power. Globally, approximately 7,000 people work for the company, in about 90 offices and branches. The head office of the holding company is located in Utrecht (Netherlands). The European headquarters is located in Schiedam (Netherlands). Mammoet has offices in North America, South America, the Middle East, Africa, Asia, and Australia.

American Market

[edit]

Mammoet made its break into America in 1989 when they established an American HQ in Rosharon, Texas, where they were awarded the factory to foundation contract for the Red Dog Project in Alaska. After that, the company acquired the Davenport and Sons, a transport company based out of east Texas to secure rights to using their SMPT (Self Propelled Modular Transporters) in Texas and Louisiana.

Mammoet used several different trucks for their upfits in the American market, including Mack RD800's, Mack Titans, Mack F700's, Mack M45SX's, Peterbilt 379's, Western Star 4900 SA's, Kenworth T800's, Kenworth W990's, Kenworth C509's, Kenworth C500B's, Kenworth 848's, and more.

History

Founding and Early Development (1807–1900)

Mammoet traces its origins to May 13, 1807, when Dutch entrepreneur Jan Goedkoop, aged 25, established a maritime company in , , under the name Gebroeders Goedkoop (Goedkoop Brothers). Goedkoop initiated operations by purchasing a 140-ton vessel, enabling the firm to engage in water-based of and passengers amid the Industrial Revolution's rising demand for reliable shipping services. The company focused primarily on maritime , leveraging the ' extensive canal and river networks to facilitate trade and industrial goods movement in an era of expanding European commerce. This foundational emphasis on heavy foreshadowed later specializations, as Goedkoop anticipated the need for robust hauling capabilities in a mechanizing . By 1862, Gebroeders Goedkoop expanded its fleet with the acquisition of its first tugboat, enhancing towing and maneuvering services for larger vessels and cargoes along Dutch waterways. This development marked an early shift toward more specialized maritime support, though the firm remained centered on traditional shipping until the turn of the century. Throughout the 19th century, the business operated as a family enterprise, building a reputation for dependable transport without significant diversification beyond waterborne activities.

Growth in Maritime and Industrial Sectors (1900–1960)

In the early 1900s, Reederij Gebr. Goedkoop, the maritime predecessor to modern Mammoet, continued to build on its established operations initiated in 1862 with the acquisition of the ' first firm-owned paddle tug, expanding its fleet to support growing demand for towing services in 's busy harbors and inland waterways. This period saw steady fleet augmentation, including steam-powered tugs suited for heavier loads, as Dutch maritime traffic intensified amid post-World War I reconstruction and port expansions like those in and . By 1920, the company pivoted its core business toward specialized tug and salvage operations, capitalizing on expertise in wreck removal and heavy to serve an industrializing economy reliant on reliable waterborne for , , and machinery transport. In 1922, it reorganized as N.V. Reederij v/h Gebr. Goedkoop, formalizing its status as a leading tug concern with a fleet that included numbered vessels such as the Hendrik P. Goedkoop (No. 27), enabling operations in challenging and approaches. Salvage activities grew particularly during the interwar years, addressing shipwrecks and port incidents tied to surging industrial shipping volumes, with the firm's tugs handling tows up to several thousand tons amid ' canal network facilitating inland industrial distribution. The mid-20th century marked further maritime maturation, exemplified by the 1950s adoption of advanced propulsion like the Voith-Schneider system in tugs such as the 600 BHP Jan Goedkoop Jr., the first of its kind in the Netherlands, enhancing maneuverability for salvage and industrial towing in congested waterways. Industrial sector involvement deepened through water-based heavy haulage, supporting sectors like petrochemicals and manufacturing by towing barges laden with oversized equipment via the extensive Rhine-Scheldt delta system, where annual cargo throughput exceeded millions of tons by the 1950s. HTM Goedkoop, an affiliated entity tracing to 1805 origins, complemented this by integrating early land extensions for heavyweight transfers from water to rail or road, laying groundwork for hybrid maritime-industrial logistics amid postwar economic booms. By 1960, the combined operations boasted a robust tug fleet integral to Dutch industrial supply chains, though full-scale heavy-lift specialization awaited later mergers.

Expansion into Heavy Lifting and Global Operations (1960–2000)

In 1971, the Dutch firms HTM Goedkoop and Van Wezel merged to form Mammoet Transport, combining expertise with land-based heavy lifting capabilities. This was followed in 1972 by the acquisition of Stoof , a specialist in engineered heavy lifting and transport, which strengthened Mammoet's position in crane operations and modular transport systems. In 1973, Mammoet became a of Koninklijke Nederlandse Stoomboot-Maatschappij (KNSM) and established Mammoet Shipping B.V., acquiring the heavy-lift vessel Happy Pioneer to enable integrated "factory-to-foundation" services worldwide. The mid-1970s marked technological advancements in heavy lifting, including the development of the Hydra-Jack hydraulic jacking system, which achieved capacities exceeding 7,000 tons across nearly 20 units and positioned Mammoet as a leader in international heavy-lift projects. Global operations expanded with entry into the in 1974 for nuclear power station component deliveries to , followed by vessel additions like Happy Rider and Happy Runner in 1976. By 1979, acquisition of Big Lift enhanced presence through Alatas Mammoet in , while 1981 integration into Koninklijke Nedlloyd's heavy transport division supported further international growth. In 1983, Mammoet pioneered the (SPMT), a configurable system that became an industry standard for transporting massive loads over land. Subsequent decades saw accelerated global footprint development, including North American entry via Mammoet Western Inc. in 1987 and full Canadian ownership by 1993, alongside Asian ventures such as 88% control of Skanza Mammoet in Malaysia by 1994. A 1984 partnership formed Mammoet Heavy Lift Partners to manage a shared global fleet of heavy-lift vessels, while 1986 involvement in Chernobyl's sarcophagus project demonstrated capabilities with custom lifting and skidding for a 36,200-ton structure. In 1995, merger with Decafin's operations created Mammoet Decalift International B.V. (67% Mammoet-owned), incorporating cranes with up to 1,200-ton capacities and boosting European and global reach. By 1996, annual sales reached NLG 320 million (approximately US$160 million), supported by a fleet including Happy Rover, Happy Ranger, Happy River (delivered 1997), and Sailer Jupiter; subsidiaries operated across Europe, the Middle East, North America, Asia, and Africa. The period culminated in 2000 with merger into Van Seumeren Kraanbedrijf, further consolidating heavy lifting resources.

Mergers, Acquisitions, and Modern Restructuring (2000–Present)

In 2000, Mammoet was acquired by and merged with Van Seumeren Kraanbedrijf, a Dutch heavy lifting firm founded in , forming a combined entity that retained the Mammoet name and expanded its operational scope in heavy transport and cranes. In 2001, the company divested its maritime shipping division, Mammoet Shipping, to the Spliethoff Group, allowing refocus on core land-based heavy lifting and transport activities. SHV Holdings, a privately held Dutch conglomerate, acquired a 75% stake in Mammoet in 2006 for approximately €400 million, with the transaction approved by the ; SHV later obtained full ownership, integrating Mammoet into its portfolio of industrial services companies. In March 2023, SHV announced plans to explore divesting Mammoet as part of a strategic review, soliciting bids from potential buyers, but reversed the decision in July 2023, opting to retain the subsidiary due to its alignment with long-term growth objectives. A significant expansion occurred in 2020 when Mammoet completed the acquisition of ALE, a UK-based heavy lifting and specialist, integrating ALE's operations under the Mammoet brand and creating a combined workforce of nearly 6,800 employees with enhanced global capabilities in engineered solutions. Additional asset acquisitions included the 2021 purchase of linear winch equipment from J. Murphy & Sons' Land & Marine division, bolstering specialized pulling technologies. In 2024, Mammoet initiated Project Elevate, an internal restructuring dividing the company into two distinct business units: one focused on large-scale, project-based engineered heavy lifting and transport, and the other on crane rental and shorter-term hires. This reorganization, aimed at improving agility, efficiency, and client-specific deployment of resources, involved portfolio simplification and asset optimization without altering ownership.
