由于深水半潜式起重铺管船上2×8000 t浮式起重机在起重量和回转起重力矩等各方面技术参数已远超现有起重机，且作业海况与ABS设计标准中规定的重型起重机无法完全吻合，为保证浮式起重机的安全性，对其数字化样机在船体运动及自身机构动作下进行运动分析，并结合API标准对其起升动载系数进行校核，以确定其最大起重量时的适宜海况。

Since the lifting weight, rotation load moment and other technical parameters of 2 ×8 000 t floating crane on the deep-water semi-submersible hoisting pipe-laying ship are larger than existing cranes, and the sea conditions during its operation are different from those for the heavy crane specified in ABS design standards.To guarantee safety of the float-ing crane, motion analysis is performed on the digital prototype during the action of the ship motion and self-motion, and the lifting dynamic coefficient is verified based on API standards to determine the proper sea conditions for the maximum lifting weight.
