Incat Crowther crewboat under construction in Brazil

The new vessel complies with the Petrobras specifications for the P2-type crew boat and is one of the first projects undertaken by Incat Crowther’s new USA office following the integration of Alliance Marine Design.

The BV-classed vessel has a beam of 7.5m, a draught of 1.2m and the main cabin contains seating for 60 passengers and there is a crew capacity of ten. Aft of the passenger accommodation is the main cargo deck, which is divided to perform two main functions. The aft area is devoted to crew transfer, allowing for safe and trouble free transfers to offshore platforms. The forward portion is configured to carry cargo, with a capacity of over 50 tonnes. The newbuilding is also equipped with cargo fresh water and fuel tanks each capable of holding in excess of 30,000 litres.

The wheelhouse is located on the upper deck and includes forward and aft facing control stations, with all round visibility. The upper deck also features a rescue boat with slewing davit, fire fighting monitor and direct access to both forward and aft decks. A purpose-designed transfer platform has been arranged on the foredeck to further suit the Petrobras P2 vessel requirements.

The vessel will be powered by three Caterpillar C32 main engines, each driving a Hamilton HM721 waterjet. The centre drive line will be arranged to provide booster power, while the outboard jets will add steering functionality. A ZF3050 gearbox will provide gear reduction and clutching. A single 74kW bow thruster will be installed for station keeping purposes. The three Caterpillar main engines produce a total of 3,130kW, giving the vessel a service speed of 25 knots.

Primary electrical power is derived from a pair of Caterpillar C4.4 gensets each producing 99kW.
