AI Technical Summary

Problems solved by technology

[0005] In addition, if the phenomenon of VIM (Vortex Induced Motion) on the MPSO begins to appear, lateral movement will occur, causing the mooring line of the MPSO (or the composite mooring line composed of chains and synthetic fiber cables) to also move, so if at this time The shuttle tanker is very close to the MPSO, and it is possible that the shuttle will occur on the berthing line, and even the shuttle tanker may collide with the MPSO; on the contrary, if the shuttle tanker is far away from the MPSO at this time, there may be a hose danger of oil spill

Embodiment 1

[0045] A method of maintaining the heading and relative position between a buoy and a vessel comprising:

[0046] A plurality of sensors for detecting the surrounding environment data of the floating body are arranged on the floating body, and the state data of the surrounding environment of the floating body are collected in real time;

[0047] Constructing a floating body historical environment database according to the status data of the surrounding environment of the floating body collected in different time periods or seasons throughout the year;

[0048] A plurality of sensors are arranged on the ship to detect the data of the surrounding environment of the ship, and the data of the surrounding environment of the ship are collected in real time;

[0049] Constructing a ship historical environment database according to the status data of the surrounding environment of the ship collected in different time periods or seasons throughout the year;

[0050] Real-time collecti...

Abstract

The invention relates to a method and device for keeping the stem orientation and the relative position between a floating body and a ship. The method includes the steps that multiple sensors for detecting condition data of the peripheral environment of the floating body are arranged on the floating body, and the condition data of the peripheral environment of the floating body is collected in real time; a floating-body historical environment database is established according to condition data, collected in different time periods or seasons all the year, of the peripheral environment of floating bodies.

Description

technical field [0001] The invention relates to a method and device for maintaining the bow orientation of a shuttle tanker and maintaining the relative position between a floating body and the ship. The method and device are especially suitable for a liquid carrier whose navigation target is a fixed platform or a floating platform at sea (such as shuttle tankers). Background technique [0002] In subsea oil production systems, offshore platforms are often used as floating bodies. General floating offshore oil production, storage, and loading equipment include FPSO: In recent years, compared with FPSO, MPSO, which has superior motion performance, has proposed concepts such as single-column floating production systems. MPSOs are specifically cylindrical or polygonal floating bodies that store the oil produced therein. [0003] In order to safely and conveniently transfer the stored liquid to the shuttle carrier, offshore platforms and structures (such as FPSO) with liquid s...
