Incat Crowther Delivers SEACOR Marine’s 2nd FSV

Incat Crowther announced the delivery of Najla McCall, the second vessel in SEACOR Marine’s Express Plus class of Fast Support Vessels (FSV).

Sistership to the Alya McCall launched in November last year, Najla McCall has seating capacity for 100 personnel and achieved an operational speed in excess of 38 knots during recent trials. This performance is remarkable for a large vessel of this type and is enabled by a quintet of Cummins QSK 60, EPA Tier 3 compliant diesel engines, each producing 2,680 bhp, the designer said. The engines are coupled to Twin Disc MGX 61500 SC reverse reduction gearboxes driving Hamilton HT-810 water jets through a shafting system by Driveline Service of Portland.

Station-keeping capability is provided through the combination of three Thrustmaster 30TT200 electric-mechanical tunnel thrusters in working in conjunction with the azimuth-like waterjets, all of which are controlled by a Kongsberg K-Pos DP-2 dynamic positioning system.

Electrical power is derived from three Cummins QSM11 gensets, each producing 290 ekW. Dual FFS firefighting pumps and remoted controlled monitors provide Fifi-1 equivalent firefighting capacity for combatting off-ship fires. A Naiad Dynamics ride control system is also fitted to improve passenger and crew comfort while underway.

The vessel is certified by the USCG and by the American Bureau of Shipping as a High-Speed Craft with DP-2 and Fire-Fighting Capability notations.

Najla McCall was constructed by Gulf Craft in Franklin, Louisiana, who are well progressed on construction of additional Express Plus class units.

This latest delivery complements previous very fast vessels including the Alya McCall and the Crewzer class of very fast catamarans all of which are the result of Incat Crowther’s partnership with SEACOR Marine and Gulf

Craft. All three parties share a commitment to service and a philosophy of innovation.
