OSLO, NorwayDolphin claims to have mobilized the “world’s largest floating object” off the coast of Myanmar.

The contractor deployed a seismic spread of 12 streamers, each 7,050 m (23,130 ft) long with 150 m (492 ft) streamer separation for Ophir Energy.

This equipment configuration has a moving width of 1,850 m (6,069 ft) and the seismic spread covers a total area of around 12 sq km (4.6 sq mi).

Bjarne Stavenes, vice president technical, said: “Ophir Energy challenged the industry to provide a cost efficient solution to acquire their large 10,000-sq km [3,861-sq mi] survey in Myanmar. Dolphin responded by offering this ultra-wide towing solution.

“After a swift mobilization, Dolphin’s Sanco Sword is now in steady production with acquisition of about 150 sq km [58 sq mi] in a single day. This is believed to be a world record for our industry.”

In addition, Dolphin is supplying a fasttrack on-board processing system powered by its proprietary OpenCPS software. The company’s processing office in Singapore will deliver the resultant pre-stack time migrated SHarp Broadband dataset.
