Great Ship - Geco-Eagle

December 7, 1999

Signifying the best of an outstanding new crop of seismic vessels, the Norwegian-built wedge-shaped Geco Eagle sports a 121 ft. (37m) wide back deck to store and deploy more recording equipment than any other vessel afloat, but the unique shipshape does not lead to a trade-off in capacity. The ability to survey more territory in a time and cost efficient manner has directly led to the tremendous push for deeper water resources exploration. Geco-Prakla routinely deploys 6 km streamers and the slim Nessie-4 streamers and large streamer reels will enable Geco Eagle to easily deploy streamers over 8km. Geco Eagle is equipped with the Monowing* II deflector system, which coupled with lightweight towing leads, has already been proven to deliver 1,400 meter wide spreads without the help of other vessels. The highest capacity vessels previous to Geco Eagle in the Schlumberger (SLB) fleet were already deploying footprints up to 8 sq. km. Geco Eagle — if you can excuse the expression — effectively knocks all existing records out of the water with its massive footprint up to 11 sq. km. With 20 tow points, Geco Eagle is able to shoot very high-resolution 3-D. It is not only the vessel’s capacity, but also its flexibility that sets Geco Eagle apart. Geco Eagle has a specially designed 36-ft. (10.9 m) workboat that is easy to deploy, is completely self-contained — with enclosed cabin and navigation system and is very fast moving. It can pick up, exchange and store 100 m streamer sections, has underwater cameras and a unique streamer cleaning system. Geco-Prakla vessels have already kept streamers deployed for well over a year and have encountered barnacles and other growths of amazing proportions. With its five-year docking interval, Geco Eagle streamers are likely to spend a very long time continuously deployed in the water.
