Case Study: SEACOR Marine achieves high-speed crew boat performance with Cummins power systems

Seacor Marine Takes Delivery of 10,800 HP Crew Boat

SEACOR Marine needed a high-powered, efficient propulsion package for its new, larger mono-hull crew/supply boat, the Alex F. McCall, which was designed to carry significant fuel, water, cargo, and passengers while operating at high speeds. To meet these demands, the company turned to Cummins for marine engines and power generation equipment.

Cummins supplied four QSK60 Tier 3/IMO Tier 2 main engines, each rated at 2,700 HP, along with three QSM11-powered 290-kW generators. The engines drive Hamilton HT810 water jets, enabling the vessel to reach 32 knots maximum speed and cruise at 26 knots, while also supporting DP-2 capability through electric tunnel bow thrusters. At 26 knots, the vessel burns 366 gallons per hour, dropping to 264 gallons per hour at 22 knots, delivering strong performance with measurable fuel-efficiency benefits.
