Island and reef exploration rov water surface deployment recovery system and its recovery method

Abstract

The invention relates to an island reef exploration ROV water surface distribution and recovery system and a recovery method thereof. The system includes a mother ship. A transport bench for transporting ROV is installed at the front end of the deck of the mother ship, A floating ball platform and a cable guide are adjacent to each other on the deck beside the transport platform, A crane and a winch are sequentially arranged on the deck behind the cable guide, An umbilical cord cable and a cable clamp are arrange behind that winch, and the crane lifts the ROV into the deep sea. At this time, the end of the umbilical cord cable is fixed by the cable clamp, and the rear end part is connected to the control room of the mother ship, and the other end of the umbilical cord cable bypass the winch and is connected with the ROV through the cable guide and the automatic dismounting floating ball platform. Through the use of winch, cable guide, crane and other equipment to achieve the placementand recovery of ROV, and the use of winch to achieve the placement of umbilical cord cable, recovery, the use of cable guide to reduce the friction between umbilical cord cable and the ship side, theuse of crane to achieve the hoisting and placement of ROV.

Description

technical field [0001] The invention relates to the technical field of water surface deployment and recovery systems, in particular to a water surface deployment and recovery system and a recovery method thereof for island and reef exploration ROVs. Background technique [0002] The seabed topography near islands and reefs is complex. When carrying out construction operations in islands and reefs, ROVs are generally used to conduct detailed exploration of the seabed topography. When using ROV for underwater exploration, if an engineering vessel equipped with an A-frame is used for the operation, the cost is high; if a general vessel is used for lifting with a ship-mounted crane, and the crew cooperates to retract and release the umbilical cable, the safety and efficiency are low. high. [0003] In order to reduce the cable diameter, the umbilical cables of conventional ROVs often sink into the seabed in a state of negative buoyancy in the water, and cable entanglement event...

Problems solved by technology

When using ROV for underwater exploration, if an engineering vessel equipped with an A-frame is used for the operation, the cost is high; if a general vessel is used for lifting with a ship-mounted crane, and the crew cooperates to retract and release the umbilical cable, the safety and efficiency are low. high

[0003] In order to reduce the cable diameter, the umbilical cables of conventional ROVs often sink into the seabed in a state of negative buoyancy in the water, and cable entanglement events are very prone to occur when navigating in island and reef areas
