Embodiment Construction

[0044] The cabins, floating bodies, and optoelectronic composite umbilicals in the large water depth and current-resistant mooring system based on photoelectric composite umbilicals are subjected to complex dynamic loads in the marine environment, and are the weakest parts in the application of marine mooring systems. The profile design, structural design, buoyancy ratio and parameter design of marine accessories in the mooring system are the keys to the static and dynamic analysis of hydrodynamics, which directly affect the function realization, service life and construction cost of the mooring system. Therefore, it is necessary to design and analyze the mooring system according to factors such as environmental conditions, equipment functions, parameters, project requirements and domestic R&D capabilities of umbilicals.

[0045] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying ...

Abstract

The invention relates to an ocean anchoring system, in particular to a large-water-depth anti-flow type anchoring system based on a photoelectric composite umbilical cable. Wherein the photoelectric composite umbilical cable (16) between the umbilical buoy (18) and the underwater electronic equipment is arranged to be a catenary, and provides lateral tension and torque for a main cabin body (25) of the main mooring anchor system (2) and the umbilical buoy (18), so that the photoelectric composite umbilical cable (16) between the main mooring anchor system (2) and the umbilical buoy (18) and the umbilical mooring anchor block (14) is in a line type required by design; the main cabin body (25) is subjected to vertical tension provided by the main mooring anchor system (2) and lateral tension provided by the photoelectric composite umbilical cable (16), so that the posture is kept stable.

Description

technical field [0001] The invention relates to an ocean mooring system, in particular to a large water depth and anti-current mooring system based on a photoelectric composite umbilical cable. Background technique [0002] The ocean is the cradle of life and an endless treasure. Knowing the ocean world and cultivating the blue land is the only way for my country to become a maritime power. The mooring system has a wide range of applications in marine seabed geological survey, hydrological resource survey, detection, and development of various oil and gas resources. Since the deep-sea mooring system works in a complex and harsh marine environment with large water depths, the mooring system with energy supply and information transmission functions is subjected to various flow loads and disturbances, which will adversely affect the equipment carried by the mooring system. Stability design methods put forward higher requirements. [0003] In the prior art, the single-point mo...
