Method for cargo carrying of semi-submerged ship based on deep and open sea conditions

Abstract

The invention discloses a method for cargo carrying of a semi-submerged ship based on deep and open sea conditions. The semi-submerged ship reaches the cargo loading preparation position and is submerged to the specified draft position and kept stable through a power positioning system of the semi-submerged ship; the semi-submerged ship is moored with a cargo through auxiliary ships, a front traction winch is connected with the front end of the cargo through a front traction rope also serving as a control cable, and a rear traction winch is connected with the rear end of the cargo through a rear traction cable also serving as a control cable; the auxiliary ships and the cargo are towed alongside, the front traction winch and the rear traction winch pull the cargo or control the cargo state through the front and rear traction cables also serving as the control cables, and thus the cargo moves according to a preset trajectory in the traction process and finally reaches the cargo loading position; then the cargo is centralized through a centralizing device; the semi-submerged ship floats upwards, and cup supports are supported between the cargo and the semi-submerged ship in a buffer mode; and after the semi-submerged ship completes upward floating, the centralizing device is moved to clamp the cargo. According to the method, the semi-submerged ship can work in a deep and open sea, in addition, the loading process is simplified, the loading time is shortened, and the loading efficiency is improved.

Description

technical field [0001] The invention relates to the field of water machinery, in particular to a method for carrying cargo on a semi-submersible ship based on deep sea conditions. Background technique [0002] With the vigorous development of the ocean engineering industry and related technical fields, human beings are exploring the ocean more and more deeply due to the development and utilization of the ocean environment and resources. During the voyage of the ship, it is inevitable that there will be various failures. For some ships that have lost power, they are often towed by tugboats to the nearest port for maintenance or transported back to the country by semi-submersible ships. The transportation of today's semi-submersible ships is limited to the port area, requiring a lot of auxiliary equipment to assist the semi-submersible ships to carry out the loading work, which is cumbersome and time-consuming. Moreover, some potential safety hazards often appear during the t...

Problems solved by technology

[0003] In view of the above problems, the present invention proposes a method for carrying cargo on a semi-submersible ship based on deep sea conditions, aiming to solve the problem that the semi-submersible ship cannot be loaded under deep sea conditions, so that the semi-submersible ship can be carried without shore-based assistance. Under this condition, cargo loading can be realized in the deep sea area
