Abstract | Recently, an OSV (Offshore Support Vessel) is being widely used to install an offshore structure such as a subsea equipment which is laid on its deck. The lifting operation which is one of installation operations includes lifting off, lifting in the air, splash zone crossing, deep submerging, and lastly landing of the structure with an OSV crane. There are some major considerations during this operation. Especially, when lifting off the structure, if operating conditions such as ocean environmental loads and hoisting (or lowering) speed are bad, the excess of tension of wire ropes of the crane and the collision between the OSV and the structure can be occurred due to the relative motion between them. To solve this problem, this study performs the lifting simulation while the OSV installs the structure. The simulation includes the calculation of dynamic responses of the OSV and the equipment, including the wire tension and the collision detection. To check the applicability of the simulation, it is applied to some lifting steps by varying operating conditions. As a result, it is confirmed that the conditions affect the operability of those steps. |
