Ulstein delivers Blue Guardian supply vessel for the North Sea

STAVANGER -- The platform supply vessel Blue Guardian has delivered from shipbuilder Ulstein to Blue Ship Invest. The vessel is contracted to work in the North Sea.

Blue Guardian is the fifth in a series of six platform supply vessels (PSV) of the PX121 design from Ulstein Verft, and the vessel is under the management of RemØy Shipping. From mid-July, the ship has been contracted by Det Norske Oljeselskap ASA and Repsol Exploration respectively, to support the jackup rig Maersk Giant in its work on two subsea wells on the Norwegian continental shelf in the North Sea.

Blue Guardian has a length of 83.4 m and a beam of 18 m, and keeps a maximum speed of approximately 16 knots. She has a load capacity of 4,200 tonnes (dwt), and the 850 sq me cargo deck can carry a deck load of 2,200 tonnes. In addition to tanks for oil, water and drilling fluids, the vessel has four stainless steel tanks for flammable liquids. Blue Guardian has accommodation for 23 persons, is equipped with a dynamic positioning system IMO class II and meets the requirements of DNV’s Clean Design notation.

The latest vessels in the series have been adapted to requirements for work in the Norwegian sector. That includes more power in order to keep position in foul weather at rig, and NOx reduction for the exhaust emissions. In addition, the latest vessels carry the light ice class (ICE-C), to be prepared for work further north.

In the North Sea, PSVs of the PX121 design are considered medium-sized. The vessels of this design have an optimal combination of fuel-efficiency and deadweight. They have the capacities and performance close to the segment for larger PSVs, but at a cost that provides excellent value-for-money.

The vessels’ X-BOW hull line design 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, beneficial qualities in terms of motion and propulsion efficiency in heavy seas. Both the hull and choice of propulsion system make the vessels particularly suited for North Sea and North Atlantic conditions.

The first ship in this series was delivered in 2012, and all four of the previously delivered vessels to Blue Ship Invest have entered into firm contracts.
