The three year old 'Polarcus Naila' will visit Shipdock Amsterdam for a full propulsion upgrade

Shipdock Amsterdam, part of Damen Shipyards Group, has received a contract to upgrade the propulsion of the Polarcus owned 3D seismic vessel ‘Polarcus Naila’.

Polarcus Naila will arrive at Shipdock in February 2014 for the six week week conversion. Damen said that the refit is necessary after only three years so that the vessel can be newly classified as a special purpose ship.

Flip van der Waal, general manager, Shipdock, told The Motorship: “The reason behind the conversion is to improve vessel’s bollard pull and fuel efficiency. Increase in bollard pull allows for an upgrade to a full 12 streamer capability which improves efficiency during seismic survey activities.”

He added that the refit will also result in an increase in fuel efficiency which is in line with Polarcus’ aim to to demonstrate leadership in environmental responsibility.

The electrical repairs and modifications have been subcontracted out to marine electrical engineering expert, Alewijnse Marine Systems. The main element of its work will be the delivery, pulling, installation and connection of four kilometres of power cables for the new propulsion rooms; but also new lighting, breakers davits and winches.

Work will also include the installation of a ballast water treatment system, a new workboat and davits, relocation of the MOB and the five year special survey.

Pre-fabrication work on the two gondolas has already started at Niron Staal, a specialised steel construction and machining company located on the Shipdock premises, which also part of Damen Shipyards Group.

Polarcus Naila is a 12-streamer 3D/4D Seismic Vessel. Delivered in 2010, the vessel is built to the Ulstein SX124 design and incorporates the Ulstein X-Bow hull.
