Stril Barents PSV: Cooperation Unlimited
VARD delivered the Stril Barents Platform Supply Vessel (PSV) to its owner Simon Mokster Shipping, a Norwegian shipping company. The naming ceremony was held at Skagenkaien in Stavanger, Norway in February 2015

Simon Mokster is on a ten year service contract with ENI Norge to employ the Stril Barents for supply and standby services to the Goliat offshore oil and gas field located in the Barents Sea. The contract started in February 2015.

Combining platform supply and emergency response abilities, this unique vessel is custom built for the rough Arctic conditions in the Barents Sea and is a result of close cooperation between Simon Mokster Shipping, VARD, and ENI Norge.

Stril Barents replaces Esvagt Aurora as the standby vessel at the Goliat fields that starts production from mid-2015. The vessel will also render oil spill cleaning duties as well as search and rescue operations.

ENI Norge signed the contract with Simon Mokster in April 2013. Simon Mokster signed a letter of intent with VARD Design in the same month to design and build a PSV. The VARD Braila Shipyard in Romania developed the vessel’s environment friendly hull while the VARD Aukra Shipyard in Norway built the ship.

Design & Technical Details
Based on VARD 1 06 LNG environment friendly design, the Stril Barents is capable of operating even in extreme Arctic conditions while maintaining excellent seakeeping, great nautical station keeping, and low fuel consumption. It is tailor designed and equipped for platform supply operations across the world.

Seakeeping is the capability of a vessel to sail safely at sea for long durations of rough, stormy weather. Nautical Station Keeping is the maintenance of a ship’s position relative to other vessels in a fleet. Station keeping also means maintaining fixed position with respect to a fixed object or patrolling a defined area in relation to a fixed object.
