Polarcus Adira (SW Baret)
New name: SW Baret. A 3D 12-14 streamer seismic research vessel, ice-reinforced with thicker ribs and skin plates, with de-icing and ice-preventing systems at critical tanks and pipelines. Propellers, gears and thrusters dimensioned for operations in ice. Escape corridors and rescue equipment protected against icing.

Ship history
The Polarcus Adira (first name) was delivered from Ulstein Verft on 21 June 2012. The vessel is based on the ULSTEIN SX134 design.
The vessel can operate in first-year ice of up to 1 metre thickness without the assistance of icebreakers. A number of environmental initiatives were implemented in the design and building of the vessel. Her double hull, along with her advanced bilge water cleaning and ballast water treatment systems, reduces emissions to water to a minimum. The vessel runs on marine gas oil (MGO) with low sulphur content and has high-specification exhaust catalysts that clean the exhaust before it is emitted into the air. She is also equipped with a diesel-electric propulsion system. The vessel's X-BOW® hull line design reduces fuel consumption and therefore emissions to the air. The vessel carries the Clean Design notation from DNV.
'ULSTEIN set the standard with the punctual delivery of Polarcus Amani in March this year, and with the delivery of Polarcus Adira, they have once again lived up to their reputation as a reliable partner with the ability to deliver quality vessels on time,' said CEO of Polarcus, Rolf Rønningen.
Polarcus Adira commenced her first seismic acquisition charter for TGS-NOPEC Geophysical Company (TGS) offshore Norway shortly after delivery.
