Incat Crowther has been awarded a contract with shipbuilder Astinave EP of Guayaquil, Ecuador
for the supply of vessel design services and aluminum component kits for a pair of 22.5m monohull crewboats currently under construction for an undisclosed client. The vessels will operate in support of Ecaudor’s state-owned oil and gas company
, Flota Petrolera Ecuatoriana (Flopec).
Incat Crowther said the 20-knot crewboats feature modern styling combined with a robust and simple-to-build structure. Propulsion is enabled by two Cummins QSK19 marine engines rated at 750 bhp at 1,800 rpm driving Teignbridge fixed pitch NiBrAl propellers. Electrical power is supplied by two Cummins 55MDDCM generator sets each rated at 55 ekw at 1,800 rpm.
Tank capacities include 11,000 liters of fuel oil
and 7,000 liters of potable water.
The crew accommodations resting ahead of the engine room features private staterooms for three crew, with each a locker cabinet for storage. A galley, mess area and washroom complete the crew accommodations.
The main deck includes a generous 40m2 cargo deck covered in hardwood planking and a passenger cabin featuring 25 seats, two water closets, luggage shelves, two PFD storage lockers, and a deck locker.
On the upper deck sits the pilothouse complete with forward and aft facing helm positions and a chart table. Two inflatable life rafts are aft of the wheelhouse and are arranged for easy launching.
According to Incat Crowther , the supply of the aluminum kits represents another capability of outside of its vessel design capabilities. The kits were processed by U.S.-based suppliers and shipped sea-freight from Houston to Guayaquil. Completion of the vessels is scheduled for October.
