Incat Crowther has announced the delivery of Najla McCall, the second vessel in SEACOR Marine’s Express Plus class of Fast Support Vessels (FSV).
Najla McCall is a sister ship to the Alya McCall, launched in November last year.
According to Incat Crowther, the Najla McCall has seating capacity for 100 personnel and achieved an operational speed in excess of 38 knots during recent trials. This performance is enabled by a quintet of Cummins QSK 60, EPA Tier 3 compliant diesel engines, each producing 2680 bhp.
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.
The company also explained that station-keeping capability was provided through the combination of three Thrustmaster 30TT200 electric-mechanical tunnel thrusters in working in conjunction with the azimuth-like waterjets, all of which were 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, Incat Crowther said.
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 is also progressing with construction of additional Express Plus class units.
