    Siem Piata was built in Brazil for Siem Consub.

    Incat Crowther has announced the launch and delivery of the 36m monohull crewboat Siem Piata.

    The vessel was launched by ETP Engenharia Ltda in Rio de Janeiro, Brazil, successfully completed sea trials and was delivered to Siem Consub for service to Petrobras.

    Developed primarily at Incat Crowther’s USA office in Morgan City Louisiana, Siem Piata will perform the role of a P2 crewboat in the Siem Consub fleet.

    The vessel is certified to Bureau Veritas and Brazilian Maritime standards.

    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.

    The vessel features a large aft main cargo deck devoted to crew transfer and cargo carrying. Siem Piata has a deck cargo capacity of 50 tonnes.

    Below decks accommodation includes sleeping quarters for 10 (including two with ensuites), galley, mess, crew wet room, toilets and showers and a laundry.

    Below deck tankage includes cargo fresh water and fuel tanks, each capable of holding in excess of 30,000 litres. Multiple transfer pumps are provided for both cargo fluids. 15,100 litres of ship’s fuel and 5,800 litres of ship’s water are also provided.

    The vessel is powered by three Caterpillar C32 main engines, each driving a Hamilton HM721 waterjet. A ZF3050 gearbox will provide gear reduction and clutching. A single 100 hp bow thruster will be mounted forward for station keeping purposes. Primary electrical power is derived from a pair of Caterpillar C4.4 gensets each producing 99kW.

    The vessel also features a fire fighting monitor (6,000 litres/min) for combating off-ship fires and a purposedesigned transfer platform has been arranged on the foredeck to further suit the Petrobras P2 vessel requirements.
