Sunken ship salvage umbilical cable

Abstract

The invention discloses a sunken ship salvage umbilical cable which is suitable for salvage of seaborne large sunken ships and sunken objects. The sunken ship salvage umbilical cable comprises a cable core which is formed by twisting two stainless steel seamless pipes with extruded thermoplastic elastomer protection layers and a digital communication paired cable, and a stainless steel wire braid layer which wraps the exterior of the cable core, wherein the digital communication paired cable comprises a paired cable core, and a digital communication paired cable sheath and another stainless steel wire braid layer which sequentially wrap the exterior of the paired cable core from inside to outside and are used to seal water. The sunken ship salvage umbilical cable is used cooperatively with a deepwater and underwater guiding mud penetrator, and can be practically used for achieving the purpose of salvaging the seaborne large sunken ships and the seaborne large sunken objects.

Description

technical field [0001] The invention relates to a sunken ship salvage umbilical cable suitable for salvaging large sunken ships and sunken objects at sea. Background technique [0002] As the pace of world economic globalization continues to accelerate, the volume of global trade is also growing rapidly, and the water transportation of goods is facing new opportunities and challenges. Various large container ships, liquefied gas ships, oil tankers, and bulk carriers around the world are on the way. Developing in the direction of large-scale, the load capacity of ore carriers has reached 400,000 tons. However, large-scale shipwreck accidents also occur from time to time, blocking the main sea channel and seriously affecting the development of marine transportation. The salvage of large sunken ships has become a major problem to be solved urgently in the world now and in the future. [0003] The Ministry of Transport of the People's Republic of China attaches great importanc...

Problems solved by technology

In 2012, the Institute of Underwater Engineering of Shanghai Jiao Tong University successfully developed the world's first "Deep Eel I" deep-sea underwater guided dredger, which is the most advanced in the world for salvage of large-scale shipwrecks and sunken objects at sea. The technical problems have not been well resolved, and the equipment cannot be put into actual normal use.
