Ulstein Verft has delivered »Blue Thunder«, the fourth of six medium-sized[ds_preview] platform supply vessels (PSV) of the PX121 design to Blue Ship Invest. Owned by Blue Ship Invest, a wholly-owned company in Ulstein Group, the PSV is commercially and technically under the management of Atlantic Offshore. The vessel will enter a four-month contract with Statoil, with four monthly options.
The vessels’ x-bow hull line design offers efficiency over a wide draught range. It has 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 »Blue Thunder« has a length of 83.40 m, a beam of 18 m and keeps a maximum speed of approximately 16 kn. She has a load capacity of 4,200 dwt, and the 850 m2 cargo deck can carry a deck load of 2,200 t. In addition to the storage tanks for oil, water and drilling fluids, the vessel has four stainless steel tanks for flammable liquids. The PSV offers accommodation for 23 persons, is equipped with a dynamic positioning system (IMO class II) and meets the requirements of DNV’s Clean Design notation.
Ulstein Power & Control has delivered the electrical systems, including power distribution and electrical propulsion system, the information and communication system Ulstein COM, modular consoles and integrated navigation systems and the integrated automation system Ulstein IAS. The remaining two vessels will be delivered later this year and all six vessels are for sale.
