Seismic survey vessel owners Polarcus and Shearwater GeoServices have won charters for four vessels from Oslo-listed TGS-NOPEC.

The ships will work in Europe during 2017 and 2018.

Middle East owner Polarcus said the charterer will use two of its units to acquire 30,000 square kilometres of 3D multi-client data.

Two-thirds of the work will take place this year, starting from the second quarter.The
