An award-winning Rolls-Royce design of sophisticated supply ship is breaking new operational ground in the North Sea after meeting tough stability rules that allow it to carry greater volumes of noxious liquid waste and hazardous chemicals than traditional offshore supply vessels.
Operated by Farstad Shipping, the 5,800-tonne Far Solitaire is the first of its type to incorporate our wave-piercing bow design (reflected in its type name, UT 754 WP), which is sharply angled to reduce drag and penetrate oncoming waves, promoting a more constant speed and less vibration.
This not only optimises the ship’s seakeeping qualities for enhanced stability, it also means improved comfort and safety for the crew, and increased economy and reduced environmental footprint thanks to lower fuel consumption.
Moreover, Far Solitaire meets stability rules and ventilation requirements normally associated with specialist chemical tankers, which has led to its approval to carry up to 1,600 cubic metres (m³) of hazardous waste from oil and gas fields.
This is twice the limit specified by a recently-revised International Maritime Organisation regulation that now includes drilling mud and brine among the cargo, even though each may contain relatively small quantities of hazardous materials and chemicals.
While the new regulations pose challenges for many existing supply vessels, whose loads typically included up to 1,200 tonnes of mud and brine, our UT 754 WP design is expected to prove popular with offshore operators as it can carry much more cargo.
Far Solitaire’s multi-product tanks can carry various liquids – including recovered oil to a volume of 2,200m³, which would be valuable in an oil spill emergency – while cargo pumps and pipe systems are segregated to avoid mixing products. The vessel is also the first to incorporate our new remote-controlled Dual Dragline cargo rail crane with an increased lifting height and efficient vertical and horizontal load handling.
Recognition for this range of advanced capabilities came at the 2012 Shipbuilding, Machinery and Marine technology show in Hamburg, where Far Solitaire was named ‘Ship of the Year’.
