OSLO, NorwayDolphin Group ASA (OSE:DOLP) has taken delivery of the newbuild seismic vessel M/V Sanco Sword, on an initial five-year time-charter agreement with the Norwegian vessel owner Sanco Shipping AS. Dolphin Geophysical reports that the Sanco Sword has mobilized to begin acquisition of two new, prefunded multi-client 3D projects in the Barents Sea.

The Sanco Sword is the sister vessel of the Sanco Swift, also delivered from the Kleven Myklebust yard on the west coast of Norway. Both vessels are 96 m (315 ft) long and are among the most powerful seismic vessels in the world, capable of towing spreads of up to 16 streamers at 100 separation.

In the Barents Sea, the Gohta North and Maud Basin South 3D surveys, totaling almost 6,200 sq km (2,394 sq mi), will be acquired using SHarp Broadband acquisition and processing. The SHarp Broadband technique also allows high-end, fasttrack data volumes to be delivered within four weeks of acquisition. These data volumes will allow early participating companies to screen and technically evaluate the prospectivity of the acreage in the 23rd and APA 2014 Rounds.

The surveys were planned in consultation with local operators and designed with technical input from all early participating clients, who will also be involved throughout the data processing phase.

The Sanco Sword will use as many as 12 streamers with 75-m (246-ft) separation and 7-km (4-mi) offsets due to the varying geological targets within the respective survey areas, ranging from Jurassic to Permian carbonate plays.
