X-bow PSV delivered to Ulstein subsidiary

Sunday, 22 January 2012 | 00:00
'Blue Fighter' an Ulstein-built PSV just delivered to Ulstein company Blue Ship Invest Ulstein Verft has delivered the first of two medium-sized platform supply vessels for Blue Ship Invest. The 83.4m long ‘Blue Fighter’ is to Ulstein’s new PX121 design, and features Ulstein’s X-bow hull design.
According to the designer, efficiency and flexibility were the focus in the development of the PX121 design. With optimised tank capacities and flexible and segregated tank arrangements, the multifunctional vessel is designed for suitability for many types of supply contracts. The ship is 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. A diesel electric propulsion system is based on four engines, two of 2,350kW and two of 994kW.
The X-bow is intended for efficiency over a wide draught range, which Ulstein says is important for PSVs as they frequently operate with varying loads, as well as proving beneficial in terms of motion and propulsion efficiency in heavy seas. The hull and choice of propulsion system are said to make the vessel particularly suited for North Sea and North Atlantic conditions. The vessel is equipped with a dynamic positioning system to IMO Class II.
The ship has a length of 83.4m and a beam of 18m. It has a cargo deck of 875m² and a load capacity of 4,200dwt. 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 about 15 knots and accommodation for 24 persons.
The shipyard’s Ulstein Power & Control subsidiary delivered a substantial amount of equipment to the vessel, including switchboards, the Ulstein Com information and communication system, the Ulstein Nav navigation system and the Ulstein IAS integrated automation system.
“The two vessels were ordered based on market trends showing a future increase in demand for this type of PSV. We have entered into an agreement with Remøy Shipping for the management of Blue Fighter and we are negotiating interesting contracts for the ship. In the first instance the vessel will enter the North Sea spot market,” says Gunvor Ulstein, CEO of Ulstein Group and managing director of Ulstein Shipping.
“The delivery of the first PX121 confirms Ulstein Verft’s ability to build prototype vessels. Experienced people, streamlined processes and a well-established project organisation make us a competitive and reliable shipbuilding partner for advanced offshore support vessels,” says Karsten Sævik, managing director of Ulstein Verft.
Ulstein Verft was contracted to build the two vessels for Blue Ship Invest, a shipping company which is part of the Ulstein group, at the end of 2010. Blue Fighter’s sister vessel is scheduled to be delivered from Ulstein Verft in the third quarter of 2012.
