The mooring position system is another system that maintains naval vessels in specified marine waters and limits external forces to change the position of the ship or structure to maintain its position in a predetermined position until the stop due to movement. Reduce too much, like drilling rigs. All positionings are compared with each other, which anchor position compared to dynamic has less investment advantages, easy maintenance and high security. Therefore, the mooring system is widely used in offshore structures and engineering vessels. Mooring is divided into three forms: single-point, two-point mooring system and multi-point mooring system:
- Single-point mooring system (SPM): A widely used anchoring method. In practice, the structure of a ship or ocean can rotate freely around an axis, so that the mooring system with the least resistance to wind, wave and current is a single-point anchorage system.
- Two-point mooring system: An arched anchor system that is completed by a vessel or floating hull through two single anchor vessels. Its biggest feature is that it can eliminate the rotating connection in single-point anchoring, and the whole system can adopt traditional home design and construction components. The disadvantage is that the ship can not turn to maintain a fixed direction.
- Multi-point mooring systems: Often used in situations where space is too large or too small, such as a lift platform.
