Abstract: Embodiments relate generally to marine geophysical surveying. More particularly, embodiments relate to a wax application system for application of a wax coating to a surface of a streamer. An embodiment may comprise a marine geophysical survey system. The marine geophysical survey system may comprise a streamer and a wax application system operable to receive the streamer on deployment and apply a wax coating to the streamer as the streamer is being deployed from a survey vessel into a body of water.

Abstract: A method for controlling a hybrid vehicle propulsion system that includes an internal combustion engine and an exhaust after treatment device for treating exhaust gases from the engine includes determining during operation of the vehicle a value of a parameter indicative of an efficiency of the exhaust after treatment device, identifying a vehicle operation cycle start event, determining during the operation of the vehicle an engine operation history characteristic for a time interval after the vehicle operation cycle start event, and determining whether or not to control the propulsion system so as to increase the efficiency of the exhaust after treatment device, in dependence on the determined exhaust after treatment device efficiency parameter value and the determined engine operation history characteristic.

Abstract: Embodiments relate to marine streamer cleaning. An embodiment provides a streamer cleaning apparatus comprising: a housing comprising an inlet configured to receive a streamer and an outlet configured to dispatch the streamer; and scraper lamellas coupled to the housing, wherein the scraper lamellas are arranged to form an opening to receive the streamer. Methods of cleaning a streamer and streamer cleaning systems are also provided.
