Ship history

Milestones

'Polarcus Naila' is the second of six seismic vessels constructed for Polarcus at Drydocks World - Dubai. The vessel is hull number 67 and was delivered on 24 February 2010. 
The vessel´s first commission was to work off West Africa.

In 2014, the vessel underwent a conversion in order to be classified as a Special Purpose Ship. Furthermore, the scope of work included Ballast Water Treatment installation.

2021: In April 2021, Shearwater GeoServices acquired all six Polarcus vessels. The Polarcus Naila has changed name to 'SW Mikkelsen'.

2022, 20 October: Shearwater GeoServices and WesternGeco will jointly perform a newly awarded ocean-bottom node (OBN) three-month survey in the US Gulf of Mexico (GoM). Shearwater will deploy the SW Gallien and SW Mikkelsen as source vessels for the project, in combination with ROV node deployment.
