MONOHULL CREWBOAT

February 23, 2010

Incat Crowther crewboat building in Brazil

A 36 m monohull crewboat under construction in Brazil is one of the first Incat Crowther projects to benefit from the capabilities of its new Morgan City, La., office following the integration of Alliance Marine Design. Among other benefits, the Alliance acquisition gives Newport, NSW, Australia, based Incat Crowther a customer support capability in the Americas time zone.

MONOHULL CREWBOAT

Being built by shipbuilder ETP Engenharia Ltda in Rio de Janeiro, the monohull complies with Petrobras specifications for the P2 type crew boat. The main cabin contains seating for 60 passengers in large reclining seats, some at tables. There are also luggage storage racks, a beverage counter and two toilets.

Aft of the passenger accommodations 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.

Ship's crew accommodations are below decks and consist of sleeping quarters for 10 (including two with ensuites), a galley and mess, a crew wet room with multiple toilets and showers, as well as laundry facilities.

Also below deck are the vessel tanks. Aside from the ship's own fuel and water, the vessel is also equipped with cargo fresh water and fuel tanks. Each of these tanks is capable of holding in excess of 30,000 liters.

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 (10,000 liters/min) for combating off-ship fires, 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 center drive line will be arranged to provide booster power, whilst the outboard jets will add steering functionality. A ZF3050 gearbox will provide gear reduction and clutching. A single 100 hp bow thruster will be mounted forward for station keeping purposes. The three Caterpillar main engines produce a total of 4,200 hp, giving the vessel a service speed of 25 knots. Primary electrical power is derived from a pair of Caterpillar C4.4 gensets each producing 99 kW.
