rov deep sea cable laying system for manned submersible

Abstract

The invention relates to an ROV deep-sea cable laying operating system for a manned submersible. The system comprises a rendering winch and an ROV cable laying operation box which are arranged on themanned submersible, wherein one end of an umbilical cable winds a reel of the rendering winch and is electrically connected with the ROV cable laying operation box, and the other end of the umbilicalcable is connected with a remotely operated vehicle with a cable laying winch and a hydraulic source, so that signals among the remotely operated vehicle, the cable laying winch and the manned submersible are transmitted and controlled in time. The ROV deep-sea cable laying operating system for the manned submersible has the advantages that the structure is simple, and the use is convenient; the influence of sea weaves can be effectively avoided, the stealthiness is good, the security of submarine information network is ensured; a buoyancy adjusting mechanism can ensure the zero-buoyancy stateof the cable laying vehicle in water during cable laying, the consumption of ROV energy is reduced, and the laying precision of deep-sea submarine cables is greatly increased.

Description

Technical field [0001] The invention relates to the field of submersible design, in particular to an ROV deep-sea cable laying operation system used for manned submersibles. Background technique [0002] At present, underwater observation network extension cables and underwater communication optical cables are laid by surface vessels or ROVs deployed by surface vessels. During the operation, they are extremely susceptible to sea weather and wind and waves, which reduces the efficiency of cable laying. [0003] Traditional ROV (Unmanned Submersible Vehicle) cable laying, due to the large negative buoyancy of the cable laying winch, the ROV needs to turn on the vertical propeller at all times to offset the negative buoyancy of the cable laying winch, which requires a lot of energy.

AI Technical Summary

Problems solved by technology

[0002] At present, the underwater observation network extension cable and underwater communication optical cable are laid by surface ships or ROVs deployed by surface ships. During the operation, they are easily affected by sea weather and wind and waves, which reduces the efficiency of cable laying.

[0003] For traditional ROV (Unmanned Submersible Vehicle) cable laying, because the cable laying winch itself has a large negative buoyancy, the ROV needs to turn on the vertical thruster at all times to offset the negative buoyancy of the cable laying winch, which consumes a lot of energy

At the same time, with the needs of marine security construction, it is essential to build a large-scale submarine monitoring network system, and concealed operations have become a necessary condition for the construction of such systems. Traditional surface ship cable laying or ROV cable laying cannot meet the needs of concealed operations.
