This invention refers to an innovative, original and convenient Autonomous System for Rescue operations, which works on the vessel, program controlled by a software and hardware platform rescuing people overboard in an autonomous manner. The System starts operating from the moment the person falls off the deck into the water. From the moment the wrist band on the passenger makes contact with the water, it sends out a radio frequency signal with two orders: to activate an alarm and to notify a robot to start rescue operation, and it brings it to the vessel with no intervention from people, i.e., in an intelligent and autonomous manner.

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.
