Abstract

Impact load caused by dropped objects from nearby platform or tankers is one of the latent dangers for subsea equipments which are very vulnerable and difficult to repair. Therefore a protection structure is necessary for the subsea equipment to avoid impact load. This paper investigates the subsea equipment influenced by the dropped object impact loads and addresses the determination of impact load in details. The calculation method for the protection structure design is recommended here.
