A cable-direction-adaptive ROV winch applied to non-DP-equipped motherships, includes a non-DP-equipped mothership, an A-shaped support and a winch cable-drawing roller provided on the non-DP-equipped mothership, and an underwater vehicle. A pulley is rotatably connected to the A-shaped support, the underwater vehicle is connected to an umbilical cable, the umbilical cable passes around the pulley to be connected to the winch cable-drawing roller, and a locating unit for guiding the umbilical cable is provided on the non-DP-equipped mothership. The A-shaped support is provided with a rod. The pulley includes a sliding section and a rotating section, and the sliding section is annular and slides on the rod along a direction of the rod. The rod has a groove, and a bulge portion is formed on the sliding section. The rotating section is rotatably connected to an outer circle of the sliding section via a shaft bearing.

When on-water control means 20 having moving means and capable of moving near a water surface controls a multiple underwater vehicles 30 which cruise in water, the moving means 23 controls movement of the on-water control means 20 such that the multiple underwater vehicles 30 are located in a control region X where the on-water control means 20 can position the multiple underwater vehicles 30 utilizing acoustic positioning means 24 provided in the on-water control means 20. According to this, it is possible to deploy and operate the multiple underwater vehicles in water and safely and efficiently carry out survey operation and the like such as water bottom exploration.

A system for the recovery of a surface marine craft by a carrier ship includes a lifting device with which the carrier ship is intended to be equipped and which includes a lifting unit of the davit type, equipped with a lifting cable including, at one end, a connection interface, a pole bearing a guide cable, an anchor connected to one end of the guide cable, the connection interface for the lifting cable being coupled removably to the anchor, and a hauling cable. The system also includes a receiving device with which the marine craft is intended to be equipped, the receiving device including a forward module.

A field configurable autonomous vehicle includes modular elements and attachable components. The vehicle can be assembled from these modular elements and components to meet desired mission and performance characteristics without the need to purchase specially designed vehicles for each mission. The main body of the vehicle is a spherical body.

The invention relates to a system (1, 2) (1, 4) for handling marine (3) or underwater (5) drones, the system (1, 2) (1, 4) comprising a drone interface module (2, 4) and a floating pontoon (1) with two hulls (11) and an arch (10), the pontoon (1) is catamaran-shaped and delimits a downflooded reception space (17), the arch (10) comprises at least one device (12) for attachment to a winch cable, the pontoon (1) comprises devices (13) for detachable attachment to a drone interface module (2, 4) detachably and interchangeably installed in the receiving space (17), the drone interface modules (2, 4) forming an at least partially flooded docking area (23, 42) for the drone (3, 5), the drone interface modules (2, 4) have a lower portion (22, 43) configured to rest stably on a flat surface after the drone interface module (2, 4) has been removed from the pontoon (1).

A field configurable autonomous vehicle includes modular elements and attachable components. The vehicle can be assembled from these modular elements and components to meet desired mission and performance characteristics without the need to purchase specially designed vehicles for each mission. The vehicle can include a mechanisms that magnetically attaches to a ferry vehicle for transport to the location of use.

An apparatus and method transports, launches, and recovers an unmanned undersea vehicle (UUV) on a boat. A pair of support rails secures the UUV to the boat during the transport across a body of water on the boat. The support rails support the UUV in sliding movement along the support rails during the launch from the boat into the body of water and during the recovery from the body of water onto the boat. A ramp is deployed that extends the support rails into the body of water through a stern of the boat. The ramp includes a pair of alignment rails for aligning the UUV with the support rails during the recovery. A winch pulls the UUV out of the body of water during the recovery, with the winch pulling the UUV into the alignment rails and then onto the support rails in the boat.

A submersible node and a method and system for using the node to acquire data, including seismic data is disclosed. The node incorporates a buoyancy system to provide propulsion for the node between respective landed locations by varying the buoyancy between positive and negative. A first acoustic positioning system is used to facilitate positioning of a node when landing and a second acoustic positioning system is used to facilitate a node transiting between respective target landed locations.

A remote-controlled, semi-autonomous or autonomous recovery apparatus includes a drive as well as a unit for launch and recovery of an autonomous underwater vehicle. The drive is dimensioned such that a large range, such as more than 5 nautical miles, is obtained.

This document describes a system for the deployment, towing and recovery of marine equipment from a waterborne carrier, which carrier comprises a hoisting arrangement for lifting the marine equipment into the water. The system cooperates with the hoisting arrangement, and comprises a lateral deployment-recovery assembly for deployment and recovery on a lateral side of the carrier, and includes: a tow winch and an aft lateral outrigger connected to the carrier. The assembly also comprises a tow line guide and a guider winch including a guide line attachable to the tow line guide. The aft outrigger comprises a seat for the tow line guide and a sheave for the guide line to enable guiding of the tow line guide to the seat. The document also describes a method.
