Abstract

The invention discloses a self-contained mooring posture monitoring device and method; according to the invention, through the adoption of an independently storing self-contained sensor data collecting device supplied with power by a battery, water depth and inclination angle of one point on an anchor chain can be measured and stored; and the self-contained mooring posture monitoring device disclosed by the invention has the advantages of low power consumption, long monitoring lasting time, large data storage capacity and long sampling time, can freely set a sampling time, the sampling duration, a sleep time and a sampling frequency; and as a cylindrical housing is arranged, the self-contained mooring posture monitoring device disclosed by the invention has the advantages of small volume and convenience for underwater mounting; and as a metal sealed housing is arranged, waterproof and pressure resistant characteristics are achieved. The self-contained mooring posture monitoring device disclosed by the invention provides data basis to indirectly measure mooring stress through a mooring posture. Compared with the traditional monitoring scheme of directly measuring stress at the top end of the anchor chain, the monitoring scheme of indirectly measuring the mooring stress through the mooring posture has the advantages that errors caused by friction, wave frequency motion and the like are avoided and the mooring stress situation can be more truly reflected.

Description

technical field [0001] The invention relates to the field of monitoring the mooring attitude of an ocean floating platform, in particular to a self-contained mooring attitude monitoring device and method. Background technique [0002] The catenary mooring positioning system plays a very important role in the positioning of marine floating platforms. Under the comprehensive action of environmental external forces such as waves, ocean currents, and typhoons, the mooring anchor chain provides horizontal restoring force to maintain the positioning of the floating body. According to the change law of the tension in the mooring chain line and the dynamic response of the mooring system, the mutual influence relationship between the mooring system and the upper floating body can be obtained, so as to verify whether the design of the mooring chain is reasonable, and play a guiding role in the design of the mooring system in the future . It can be seen that it is very important to m...
