Marine geophysical research apparatus for e.g. seismic research application, has rigid geophysical equipment including control surfaces for controlling movement of equipment when equipment is towed in water body by project research ship

摘要

The apparatus has a rigid geophysical equipment (105) of a large length having a ratio of the length to a width dimension or a largest height of approximately 1000:1 or more. The equipment includes control surfaces e.g. retractable wings (110a, 110b), for controlling a movement of the equipment when the equipment is towed in water body (15) by a project research ship. A front end connects a rigid marine streamer to the ship. Another marine streamer supports a geophysical sensor or a cable source for towing energy sources. Spacers are placed in an external coating of an equipment section. The geophysical sensor is a pressure sensor. An independent claim is also included for a geophysical research method.
