Abstract
The area offshore North-East-Greenland (NEGS) was selected as target area for the study because NEGS area includes the most attractive frontier basins for petroleum exploration in Greenland and the fact that the severe ice conditions reduces the accessability of the area to about 1 month a year in most of the area. The project is carried out using an icebreaking seismic vessel towing conventional seismic equipment. The actual seismic lines of the regional survey may deviate from the planned lines depending of local ice conditions. Alternative seismic concepts were investigated following the requirements that operations should be possible all year round, a detailed coverage of local areas should be possible and that data quality should match industry standard of conventional seismic operations. The main result is a new seismic concept including a seismic icebreaker with an onboard submarine designed by Thyssen Nordseewerke. The icebreaker may be used for gathering 3-D seismic when the ice conditions allow towing of the seismic array. The submarine can be launched for continuation in difficult ice conditions. Problems regarding towing the streamer from a submarine was studied. Ice conditions were investigated the concept for Sea Ice Information management was prepared. The quality of the seismic
