本发明涉及海洋工程技术领域,尤其涉及一种海上平台就位方法及就位系统。其中就位方法包括:S1,在海域中确定海上平台的就位点;S2,在就位点两侧分别设置固定桩;S3,海上平台通过第一连接绳连接固定桩,海上平台远离固定桩的一侧通过第二连接绳连接有拖轮;S4,固定桩通过第一连接绳对海上平台施加的拉力的合力为F1,拖轮通过第二连接绳对海上平台施加的拉力为F2,F1与F2方向相反,F1>F2,在F1和F2的作用下,固定桩与海上平台之间的第一连接绳的长度逐渐缩短,以使海上平台朝就位点移动;S5,海上平台移动至就位点时,完成就位。本发明中能够降低就位过程中调度及协调的成本和难度,提高就位精度,缩短就位时间。
The invention relates to the technical field of ocean engineering, in particular to an offshore platform in-place method and system. The in-place method comprises the following steps that: S1, an in-place point of an offshore platform is determined in a sea area; S2, fixing piles are arranged on the two sides of the in-place point correspondingly; S3, the offshore platform is connected with a fixed pile through a first connecting rope, and the side, away from the fixed pile, of the offshore platform is connected with a tug through a second connecting rope; S4, the resultant force of the pulling force applied to the offshore platform by the fixing pile through a first connecting rope is F1, the pulling force applied to the offshore platform by the tug through the second connecting rope is F2, F1 and F2 are opposite in direction, F1 is larger than F2, and under the action of F1 and F2, the length of the first connecting rope between the fixing pile and the offshore platform is gradually shortened so that the offshore platform can move towards the in-place point; and S5, when the offshore platform moves to the in-position point, in-position is completed. According to the method, the cost and difficulty of scheduling and coordination in the in-place process can be reduced, the in-place precision is improved, and the in-place time is shortened.
