SS Shieldhall
SS Shieldhall is a preserved steamship that operates from Southampton. She is the largest operational historic steamship in Europe and one of the last reciprocating steam engined ships built, using technology that dated back to the last quarter of the 19th century and which was obsolete at the time of her construction. She spent her working life as one of the "Clyde sludge boats", making regular trips from Shieldhall in Glasgow, Scotland, down the River Clyde and Firth of Clyde past the Isle of Arran, to dump treated sewage sludge at sea. These steamships had a tradition, dating back to the First World War, of taking organised parties of passengers on their trips during the summer. SS Shieldhall has been preserved and offers cruises to the paying public.
The 1,972-ton Shieldhall was laid down in October 1954, built by Lobnitz & Co. of Renfrew for the municipal Glasgow Corporation. She was the fourth 'sludge boat' built for the Corporation to carry treated sewage from the Corporation's three treatment works (at Dalmarnock, Dalmuir and Shieldhall) to the outer parts of the Firth of Clyde for disposal at sea, and replaced an older ship of the same name (the second of the fleet to be built, in 1910).
Aside from their unglamorous and practical part in the final stage of Glasgow's city sewage system, the sludge boats also provided day trips for passengers. This practice had begun during World War I when the Corporation offered the use of its ships to give soldiers recovering from wounds trips at sea along the Clyde, out to the Firth and to off the Isle of Bute. The traditional Clyde paddle steamers that usually served the tourist and tripper market going doon the watter had all been laid-up during the war or requisitioned for naval service, but the Corporation's sludge boats continued their essential work.
In peacetime, Glasgow Corporation continued to carry passengers on its sludge boats. Their primary role - dumping the sludge - meant that they only ran on a single route to the dumping grounds and back, and they lacked the festive appeal of the paddle steamers. But the Corporation made the trips available at little or no cost, since the ships would run regardless. The ships could be booked for free by other municipal services such as hospitals, schools, care homes and trips organised by Corporation workers, and often by charities and welfare organisations. The low fees allowed pensioners and others on low incomes to enjoy a steamer trip that they would otherwise not have been able to afford. As a matter of civic pride and to combat the inevitable impression given by their primary purpose, the Clyde sludge boats were renowned for being maintained to extremely high cosmetic and mechanical standards, and were jocularly known as 'Clyde Banana Boats'. The nickname was simultaneously an ironic euphemism for their role, a nod to their cleanliness and because their livery (light grey hull and a buff funnel with a black top), was similar to the famous Fyffes Line banana boats.
The new Shieldhall of 1954 was to continue this tradition. Slightly larger than the older members of the fleet, she was of essentially the same design, with an appearance and mechanical specification familiar to naval architects of the 1890s. She was fitted out to carry 80 passengers as well as 1500 tons of treated sewage. There were open and covered decks with benches for passengers to sightsee, as well as an enclosed saloon. On a typical trip, passengers would be served afternoon tea in the saloon as the ship steamed in a wide circle to dump its cargo, thus avoiding the worst sights and smells before making the return journey.
Like all Clyde sludge boats, Shieldhall is a twin-screw vessel with two triple expansion steam engines. This was to provide extra manoeuvrability negotiating the sinuous River Clyde with its heavy maritime traffic, and to assist coming alongside the wharves at the treatment plants without the need for tugboats.
Another tradition of the sludge boats was that passengers were allowed access to the engine room while the ship was at sea and could view the machinery up close. To this end, special arrangements were made during Shieldhall's construction. By the 1950s Lobnitz usually made its engines with enclosed crankcases and pressure lubrication, but an older design with an open crankcase, exposed working parts and traditional lubrication was used in Shieldhall in order to provide interest for passengers. There are over 20 individual steam engines aboard Shieldhall, fed from a pair of traditional oil-fired Scotch boilers. With two main 800hp reciprocating steam engines, condenser circulating pumps, multiple Weir reciprocating pumps, a reciprocating steering engine, windlass and a dynamo, Shieldhall's engineering is representative of thousands of Victorian and 20th-century steamships, and is often compared to the famous RMS Titanic, just on a much smaller scale.
She was built on the classic lines of a 1920s steam tanker with a traditional midships wheelhouse. The hull was of riveted and welded construction with a slightly raked stem and a cruiser stern. Her length is 268 feet (82 m) and breadth 44 feet 7 inches (13.59 m). Accommodation was provided for 80 passengers.
