N2 - The necessity of decommissioning aging offshore structures requires heavy lifting activities using floating cranes. Hence, studies related to the dynamic response of floating cranes are essential to better understand this process and enhance safety and security. The study on offshore heavy lifting in this paper is conducted using the Boundary Element Method (BEM) and Finite Element Method (FEM). These methods serve as alternatives to laboratory testing for studying the dynamic response of floating cranes during offshore heavy lifting operations. Five (5) parameters are developed to assess their sensitivity to the dynamic response, namely suspended load, waves, crane swings, vessel draft, and mooring tension. The results demonstrate that all these parameters significantly influence the dynamic response of the floating crane. The dynamic load factor on the crane hook's static load is calculated to be 1.21, a value in accordance with the recommendations provided by classification societies. These findings indicate that the present methods are feasible for determining the Dynamic Factor under specific conditions.
