ABSTRACT

In this paper, the static characteristics and optimization of mooring system design are studied through mechanical and mathematical analysis. Firstly, based on the principles of static balance and moment balance, the stability of the mooring system and the stress of each component are analyzed when the sea surface wind speed is 12m/s and 24m/s. The relationship between the vertical projection length and the total length of the anchor chain is deduced by using the calculus method, and the critical wind speed is calculated to be 21.92m/s. Under specific conditions, when the wind speed is 12m/s, the tilt Angle of the steel drum is 2.2 degrees, the tilt Angle of each section of the steel pipe gradually increases, the anchor chain part lies flat on the seabed, the remaining part is in a curve shape, the draft depth of the buoy is 0.6816m, and the swimming area is a circle with a radius of 14.676m centered on the anchor. When the wind speed is 24m/s, the tilt Angle of the steel drum increases to 4.584 degrees, the tilt Angle of the steel pipe increases step by step, the Angle between the tangential line at the bottom of the anchor chain and the seabed is 4.4 degrees, the draft depth of the buoy increases to 0.6957m, and the swimming area is a circle with a radius of 17.7918m. The research results of this paper provide theoretical basis and specific parameter reference for rational design and optimization of mooring system
