Publication number: 20190257969Abstract: Ocean-bottom node deployment is provided. An example system includes a pulley system which includes a pulley, a traction wheel on a marine vessel and a transport line looped around the pulley and the traction wheel. A plurality of release units are coupled to the transport line at spaced intervals and are configured to selectively secure and release a plurality of ocean-bottom nodes connected respectively thereto. A deflector connects to the pulley system and is configured to position the pulley system relative to the marine vessel. A central control unit is communicatively coupled to the plurality of release units and to the deflector and the traction wheel and includes a central processor. The central processor controls positioning of the pulley system with the deflector and commands each of the plurality of release units to release each of the plurality of ocean-bottom nodes at a predefined position.Type: ApplicationFiled: January 25, 2019Publication date: August 22, 2019Applicant: PGS Geophysical ASInventor: Einar Nielsen

Patent number: 10126464Abstract: Techniques are disclosed relating to marine geophysical prospecting. According to some embodiments, a survey vessel may tow a streamer through a body of water. If the streamer needs to be maintained (e.g., cleaned, repaired, or serviced), a second vessel may lift the streamer out of the water for this purpose. Techniques are disclosed that are relevant to the handling of protruding members (such as streamer steering devices) on the streamer.Type: GrantFiled: March 31, 2016Date of Patent: November 13, 2018Assignee: PGS Geophysical ASInventors: Einar Nielsen, Karl Petter Elvestad

Patent number: 8960117Abstract: Techniques are disclosed relating to using a remote operated vehicle (ROV) to facilitate cleaning of a submerged geophysical equipment (e.g., a streamer) being towed behind a tow vessel. The ROV may, in one embodiment, attach a streamer cleaning unit (SCU) to the streamer, where the SCU is configured to clean the streamer. In another embodiment, the ROV may facilitate cleaning by cleaning the streamer itself using a cleaning attachment coupled to the ROV.Type: GrantFiled: September 7, 2012Date of Patent: February 24, 2015Assignee: PGS Geophysical ASInventors: Einar Nielsen, Kenneth Karlsen, Rune Tønnessen, Erling Vageskar, Jan Terje Rodseth, Arnt M.
