CGG Mistral Now Working Offshore Morocco

After completion of a six-month conversion at a shipyard in Germany on 15 July, the CGG Mistral is now operating a 3D survey in Morocco.

This rebuild was a major undertaking involving a tripling of the vessel's propulsion power and a complete overhaul of her stern which increased in width by 40% with a total reconfiguration of the seismic decks. The data recording room has been completely refitted and the bridge has been moved up a level. The vessel now offers a seismic capacity of ten streamers instead of the previous six.

During its first crossing, the vessel's geophysical equipment (operating with eight streamers) has been successfully deployed and tested. She has since then started commercial seismic operations offshore Morocco. The centrepiece of the new seismic equipment is the Solid Seal. Designed and manufactured by Sercel, a CGG subsidiary, the Solid Seal is the most advanced marine seismic system available today. Based on the 408 seismic technology, which has proven its exceptional reliability, the Solid Seal is the first reduced-diameter solid cable with distributed electronics. This system architecture allows single-digitised sensor recording. Featuring a totally oil-free cable, the Solid Seal is the only marine acquisition system currently available eliminating all pollution risks. This extremely robust streamer with its advanced features generates among other benefits an improved seismic vessel productivity. Finally, the new Mistral is also the first seismic vessel in the world to sail with the latest IBM server, the Regatta, enabling her to increase significantly on-board data processing capability.

CGG is now back sailing with a complete seismic fleet of six vessels, offering a new total capacity of 52 streamers. The entire fleet is fully booked throughout 2002 with some work extending into the early part of 2003.
