Ulstein Verft has recently delivered the ‘Blue Thunder’, the fourth of six medium-sized platform supply vessels of the PX121 design to Blue Ship Invest.

Owned by Blue Ship Invest, a wholly-owned company in the Ulstein Group, the platform supply vessel (PSV) is commercially and technically under the management of Atlantic Offshore.

‘Blue Thunder’ will enter a four-month contract with Statoil with four monthly options.

“We have received good feedback from the operators on her three sister vessels, and we are very pleased that this ship also enters into a contract for work in the North Sea,” says Gunvor Ulstein, CEO of Ulstein Group and managing director of Ulstein Shipping, adding that the remaining two vessels will be delivered later this year and all six vessels are for sale.

  In the North Sea, PSVs of the PX121 designs are considered medium-sized. The vessels with 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 competitive cost.

‘Blue Thunder’ has a length of 83.4 metres and a beam of 18 metres, and keeps a maximum speed of approximately 16 knots. She has a load capacity of 4,200DWT and the 850 square metre 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 Thunder’ has modern accommodation for 23 persons, she is equipped with a dynamic positioning system IMO class II and meets the requirements of DNV’s Clean Design notation.
