Incat Crowther announced construction of a 118 ft Monohull Crewboat for the Brazilian oil giant, Petrobras. This vessel is one of the first projects to take advantage of Incat Crowther’s new USA office. The vessel, under construction by ETP Engenharia Ltda in Rio de Janeiro, Brazil complies with the 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 generous luggage storage racks, a beverage counter and two toilets.

Aft of the passenger accommodation is the main cargo deck, which is divided to perform two main functions. The aft area of the deck is devoted to crew transfer, allowing for safe and trouble free transfers to offshore platforms. The forward portion of the main cargo deck is configured to carry cargo, with a capacity of over 50 tonnes.

Ship’s crew accommodation has been arranged below decks. This accommodation consists of sleeping quarters for 10 (including two with ensuites), a galley and mess as well as a crew wet room with multiple toilets and showers, as well as laundry facilities.

In addition to the crew accommodation, below deck also houses 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 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 (10,000 litres/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 centre 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 99kw.
