Ship history

Flag: Nassau, Bahamas.
 

The ship was delivered from Ulstein Verft on 29 March 2012. The entire vessel is ice-reinforced with thicker ribs and skin plates. She has de-icing and ice-preventing systems at critical tanks and pipelines, and propellers, gears and thrusters are dimensioned for withstanding operations in ice. Escape corridors and rescue equipment are also protected against icing during arctic operations. Although 3D seismic acquisition will only take place in ice-free, or possibly bergy water conditions, the arctic qualities of the vessel enables it to move through ice on her way to and from the survey area, or remain in icy areas waiting for the ice to clear, increasing the operational window of the vessel. The seismic operation room is located midship over two decks in close vicinity to the seismic winches in the work area.

The vessel's double hull and its advanced bilge water cleaning system and ballast water treatment system reduce emissions to water down to a minimum. The vessel runs on marine gas oil (MGO) with low sulphur content and has high specification exhaust catalysts, which clean the exhaust before it is emitted to air. Polarcus Amani is also equipped with a diesel electric propulsion system. The vessel's X-BOW® hull line design is another of its many green features, in that it reduces fuel consumption and therefore emissions to air.

Milestones

Feedback on the vessel's performance was gained after three months in operation: "Polarcus Amani" has operated safely, efficiently and ahead of schedule since her delivery in March. We, and our clients, are very happy with her performance to date, says Duncan Eley, Senior VP Marine Acquisition Polarcus.

21 April 2017: Entered into a 5 1/2 year bareboat charter for Sovcomflot, the second Polarcus vessel on bareboat charter for this shipowner. Changed name to Ivan Gubkin.
 

2021: In April 2021, Shearwater GeoServices acquired all the six Polarcus vessels. The vessel changed name to 'SW Bly'.
