Norway: Ulstein Splashes PSV Blue Prosper

New platform supply vessel with the yard number 294 from Ulstein Verft was successfully launched in the afternoon of May 9th 2012. The platform supply vessel of PX121 design from ULSTEIN under construction for Blue Ship Invest, a company owned by ULSTEIN, was launched from the dock after the final paintwork had been carried out inside the dockhall.

Efficiency and flexibility has been the focus in the development of the PX121 design. With optimised tank capacities and flexible and segregated tank arrangements, the multifunctional vessel is suitable for many types of supply contracts. The ship is optimised for certain types of operations and adapted to the requirements for longer and deeper boreholes and activities further from shore. In addition to tanks for oil, water and drilling fluids, the vessel has four stainless steel tanks for flammable liquids.

The vessel is built with the X-BOW® hull line design, which is particularly well-suited for this type of vessel. The X-BOW offers efficiency over a wide draught range, which is important for PSVs as they frequently operate with varying loads. Moreover, the X-BOW has unique, advantageous qualities in terms of motion and propulsion efficiency in heavy seas. Both the hull and choice of propulsion system make the vessel particularly suited for North Sea and North Atlantic conditions. The vessel is equipped with a dynamic positioning system IMO Class II.

The ship has a length of 83.4 metres and a beam of 18 metres. It has a cargo deck of 875 square metres and a load capacity of 4200 tonnes (dwt). The ship meets the requirements of DNV’s Clean Design notation and is prepared for fire-fighting class Fi-Fi II. It has a maximum speed of circa 15 knots and modern accommodation for 24 persons.

The vessel is due for delivery in August this year.
