DETERMINATION OF OPERATING RANGES OF THE LASER-OPTICAL SYSTEM OF REFERENCE POSITIONING OF FANBEAM UNDER DIFFERENT CONDITIONS OF SEA CONDITIONS

Abstract

When carrying out cargo or other operations near offshore facilities, the ship-suppliers must occupy positions that are best suited for these operations. Often during the operations, the position must be changed and approach the object at the least possible distance, which greatly increases the risk of collision with the object. This is especially important during bad weather when there is a hovering effect. Therefore, determining and maintaining the position of the vessel with the highest accuracy is an edge necessary.

The paper proposes the principles of determining the operating ranges when using the laser-optical reference positioning system Fanbeam under different conditions of sea waves.

Currently, dynamic positioning systems operate on different physical principles, but the question of the accuracy of their measurement of the position of the vessel, the determination of the errors of these measurements under the influence of excitement remain relevant.

The paper describes the main types of rolling vessel, as well as the definition of the structure of the laser-optical reference positioning system Fanbeam, which provides automatic control and hold the position of the vessel.

If there are different types of rolling (board, pitching and vertical, and their combinations) behavior of vessel is different and it also must be taken into account in the study of laser-optical reference positioning system Fanbeam. This has been taken into account when conducting research on board a vessel.
