Work worth in excess of 45M$ has been awarded by several international oil companies for the large capacity 3D vessel Geowave Master, the 2D vessel Malene Ostervold and the 3D vessel Akademic Nemchinov which is currently on a short term charter. The work includes various 3D and 2D projects in both the UK and Norwegian sectors to be acquired between May and September 2007.
