Louisiana shipbuilder Gulf Craft has delivered the third vessel in a series of new class monohull fast support vessels (FSV) for SEACOR Marine.

According to designer Incat Crowther, the vessel Libby L. McCall advances the traditional offshore support vessel model and offers a more cost efficient, comfortable, flexible, and safe option to helicopter transportation.

The vessel features redundancy to mitigate against down time or loss of functionality due to mechanical complications. Five Cummins QSK 60, EPA Tier 3 compliant diesel engines, each producing 2680 bhp, coupled to Twin Disc MGX 61500 SC gearboxes, are provided for main propulsion power. The propulsion machinery drives Hamilton HT-810 waterjets through a cardan shafting system from Driveline Service of Portland.Electrical power is derived from three Cummins QSM 11 generator sets, each producing 290ekW and offshore station-keeping and dockside maneuverability is enabled by three Thrustmaster 30TT200 bow thrusters each outputting 200 hp. Station keeping is enhanced through a Kongsberg DP-21 system providing Class 2 capability.

Additional design features include two FFS 250x350 XP firefighting pumps feeding FFS 1200LB remote-controlled monitors rated for Class 1 capacity, a Naiad Dynamics interceptor active ride control system for optimal passenger and crew comfort during transit, a fully redundant Technicold chilled water air conditioning and heating system, as well as a pair of Headhunter marine sanitation devices to help ensure the vessel remains environmentally friendly at all times. Specially designed gangways are also provided on each side of the vessel to provide safe boarding means to both crew and passengers.

The passenger lounge features spacious reclining seating in privacy pods (similar to first class airlines) along with full internet connectivity, a well-equipped snack bar area and feature LED lighting. The vessel’s crew accommodation area includes staterooms for 16 crew along with a large galley and mess area plus walk-in pantry.

Libby L. McCall is certified by the USCG under Subchapters T (Small Passenger Vessels), L (Offshore Supply Vessels) and I (Industrial Vessels) and is Classed by the American Bureau of Shipping as a High-Speed Craft with DP-2 and Fire-Fighting Capability notations.

Gulf Craft is well-progressed on construction of fourth Express Plus class unit.
