Seacor continues to build monohulls

Despite the success of their catamaran crewboats, US-based Seacor Marine continues to build their conventional crewboats.

Hull 464, to be named ‘Alice G. McCall', is currently building at Gulf Craft in Louisiana, to be delivered in August of this year. Two more conventional vessels will follow the 57.9- by 10.4-metre boat in 2009 and 2010. Five 1,342kW Cummins KTA50-M2 main engines for a total of 6,711kW will power the DP2-classed ‘Alice G. McCall'. Gears will be Twin Disc MG-6848 with 2.93:1 reduction turning four-blade Nibral propellers on five-inch shafts. The boat will have three independent rudders. A Cummins QSM11 engine will power the boat's Thrustmaster azimuthing bow thruster. An additional Cummins QSM11 will drive the two tunnel bow thrusters. The vessel's two 135kW gensets will each be powered by Cummins 6 CTA engines, as will the bulk compressor drive. Maximum speed will be 26 knots at 1,900RPM with fuel consumption at 1,590 litres per hour. Cruising speed will be 23 knots at 1,800RPM and 1,173 litres per hour fuel consumption. At the economy speed of 20 knots and 1,600RPM fuel consumption drops to 984 litres per hour.
