Seacor Marine is building ever larger and more powerful mono-hull crew/supply boats. The first of these to be delivered is the 202x34-foot Alex F. McCall with some very impressive statistics.
With a length between perpendiculars of 186 feet and a 13-foot molded depth the new vessel has a light ship displacement of 277 long tons (281.45 mt). Interior capacities include 92,418 US gallons of fuel, (349.8 cubic meters), 10,848 US gallons of drill /fresh water (41.1 cu. met.) and 3,200 US gal. of potable water (12.1 cu. mt.). Discharge rates are: for drill water 300 gallons per minute at 380 feet, for fuel oil 354 gpm at 394 feet.
The 132 by 27 foot (40.2x8.2 m.) cargo deck is estimated to have a 400-long ton (406.4 metric ton) capacity. Crew accommodation includes eleven berths in six cabins. Seating is provided for 64 passengers.
The Alex F. McCall is equipped with three Cummins QSM11 powered 290-kW main generators. In addition to pumping and general ship’s needs these also power the three electric-operated 200 HP Thrustmaster tunnel bow thrusters for the DP-2 certified crew-supply boat.
Main engines are four Cummins QSK60-EPA Tier 3 (IMO Tier 2) compliant diesels each delivering 2700 HP at 1,900 RPM. Each engine drives a Hamilton HT810 water jet to give the boat a 32-knot maximum speed. At a cruising speed of 26 knots (1800 RPM) the mains burn 366 gallons per hour. At the economy speed of 22 knots (1,500 RPM) this drops to 264 gallons per hour.
