A13 A DEEP WATER 4C 4D PERMANENT INSTALLATION PILOT Abstract 1 M.C. HODGE C. MASSACAND H. TEIGLAND M. MILLINGTON Multiwave Geophysical Company ASA Damsgårdsveien 125 N-5162 Bergen Norway This presentation outlines some of the challenges faced with the installation of a buried 4C-4D seismic cable over a deep-water oil-producing field in the Gulf of Mexico. A single 6km 4C cable was laid on the seafloor and tied back to recording equipment on the platform. The MARS field utilizes a “Tethered Leg Platform” design because of its location in over 1000 metres of water. The 4C installation design had to take
