After the recent announcement from Dolphin about mobilisation of what the company described as “world’s largest floating object” by deploying a seismic spread of 12 streamers offshore Myanmar, Subsea World News received a notice from CGG claiming the announcement as “misinformation from Dolphin”.
The Dolphin said in a press release it has mobilised the ‘world’s largest floating object’, 7,050 meters in length with 150 meters streamer separation, where the configuration of equipment has a moving width of 1.850 meters and the seismic spread covers a total area of about 12 square km.
CGG said that “this figure is less than the more impressive 13.44 sq km spread CGG announced in a press release back in April 2013”.
In April 2013, CGG announced that the Geo Caribbean operating in the Gulf of Mexico can claim the title of the largest man-made moving object on the face of the earth, with its record-breaking 13.44 km 2 towing configuration.
In that announcement CGG said: “The challenge was to design a configuration that would enable the client to meet its survey objectives in a cost-effective and efficient manner, while also achieving the survey’s geological objectives. CGG proposed a wide tow of eight streamers with a 160-m separation, 60% wider than a typical survey with a 100-m separation, enabling a greater area of data to be acquired in a single pass and hence greater production efficiency. By deploying a streamer length of 12000m, CGG delivered the long offsets required to achieve the survey’s geological objectives. The end-result is an efficient survey design and the largest single-vessel acquisition footprint in the world.”
Subsea World News has send an email to Dolphin asking for comments on this matter.
