ST Engineering’s LNG dual fuel catamaran fast crew boat

With extreme volatility in oil price, offshore operators are now more conscious of operating expenses and looking for more cost-effective transfer solutions. In response, Singapore’s ST Engineering Marine has unveiled a design for a 76 meter dual fuel LNG catamaran fast crew boat.

Collaboratively developed with Incat Crowther, has a wave piercing semi-SWATH hull form to meet its primary application of transiting at high speed with low hull motions. This innovative hull is fitted with a ride control system comprising a pair of forward-mounted active T-foils and aft-mounted active interceptors. These technologies enable comfortable high-speed transit and, coupled with a DP2 dynamic positioning system, provide a platform to operate a broad range of Walk to Work Gangways from the vessel’s rear deck.

Four ten-cylinder dual fuel engines and four waterjets give the catamaran a maximum speed of 40 knots and a comfortable cruising speed of 34 knots.

The vessel carries 150 passengers with two classes of seating, or can comfortably house 30 passengers in single cabins in an accommodation configuration that provides all the amenities required for quality offshore living.

“Committed towards green and sustainable shipping, we have set a new standard of personnel movement and ensured multi-market use for both our oil and gas as well as offshore wind clients. The accelerated development of medium speed dual fuel and pure LNG engines has created some exciting possibilities in the design of cleaner and greener ships. Despite the physical limitations of large LNG tanks, the overall functionality that can now be accommodated in large platforms has redefined comfort and safety, whilst still maintaining the speed expectations of traditional high-speed diesel engines,” said Michael Bell, Senior Vice President (Marketing and Business Development) of ST Engineering’s Marine sector.
