he delivery of Alya McCall is signi? cant in that it is the ? rst vessel in a ? eet of new class

T monohull Fast Support Vessels (FSV) for

SEACOR Marine.

Alya McCall is the ? rst vessel in the SEACOR Ex- press Plus class and features striking lines not ordinar- ily found in traditional monohull FSV designs.

Gulf Craft in Franklin, La. built the 206 x 43 x 9.25 ft. vessel. Alya McCall features seating capacity for 100 personnel and has a top speed of 38 knots.

The performance is enabled by ? ve Cummins QSK 60, EPA Tier 3 compliant diesel engines, each produc- ing 2680 bhp. The engines are coupled to Twin Disc

MGX 61500 SC reverse reduction gearboxes that drive

Hamilton HT-810 water jets.

A cardan shafting system by Driveline Service of

Portland connects the gearboxes to the waterjets.

Superior station-keeping capability is provid- ed through the combination of three Thrustmaster 30TT200 electric-mechanical tunnel thrusters in work- ing in conjunction with the azimuth-like waterjets, all of which are controlled by a Kongsberg DP-2 dynamic positioning system.

Electrical power is derived from three Cummins

QSM11 gensets, each producing 290 ekW. Dual FFS ? re? ghting pumps and remoted controlled monitors provide Fi? -1 equivalent ? re? ghting capacity for com- batting off-ship ? res. A Naiad Dynamics ride control system is also ? tted to improve passenger and crew comfort while underway.

The vessel is certi? ed by the USCG under the pro- visions of 46 CFR Subchapter T and by the American

Bureau of Shipping as a High-Speed Craft with DP-2 and Fire-Fighting Capability notations.
