An autonomous underwater vehicle (AUV) is configured to record seismic signals during a marine seismic survey. The AUV includes a body having a base (B) and first and second sides (A, C), the body having a head part and a tail part; a propulsion system for guiding the AUV to a final target on the ocean bottom; a seismic sensor configured to record seismic signals; and an anchoring system configured to rock or twist the base in a given sequence so that the base (B) penetrates into the ocean bottom.

A deployable marine system for anchoring a vessel in a body of water and to enable a user to ingress into the vessel from the body of water or egress out of the vessel and into the body of water, the deployable marine system includes an anchor-ladder device and a deployment device. The anchor-ladder device includes a first member and one or more steps, the first member including a first end and a second end. The second end is opposite the first end and is associated with an anchoring component that may anchor the vessel. One or more steps may be attached to the first member. The deployment device may be attached to the vessel, connected to the first member in proximity to the first end, and may deploy the anchor-ladder device into, or retract the anchor-ladder device from, the body of water.

A towing anchor capable of extending wing plate and an installation method therefor are provided. The towing anchor includes a main anchor plate and two wing plates which can slide outwards relative to the main anchor plate and will not be detached from the main anchor plate. The main anchor plate is anchored with a mooring steel cable connected to a towing vessel. The main anchor plate is further provided with a limit cable-receiving groove, in which first, second and third fixed pulleys are respectively provided correspondingly to each of the two wing plates. One end of a tensioning steel cable is fixed to an inner edge of the wing plate, and the other end of the tensioning steel cable sequentially surrounds the third, second, and first fixed pulleys and then passes through an opening formed at middle position of the groove to be connected to the towing vessel.
