Summary
Site-specific wave-induced hull girder loads must be calculated to enable the ultimate limit state (ULS) engineering of ship-shaped offshore installations (described in Chapters 7 and 15). Unlike trading ships which are associated with sea states of the twnenty-five-year unrestricted service condition in the North Atlantic Ocean, wave-induced hull girder loads of ship-shaped offshore installations are defined in association with survival conditions of most probable extreme waves for a one-hundred-year return period as far as they always remain on site. However, ship-shaped offshore installations with single-point or turret mooring systems can be disconnected if extreme environmental loads are imminent, sailed to sheltered areas and then returned to restart operation when the weather calms (described in Section 9.4). Also, environmental conditions in some regions may be fully benign accommodating spread mooring systems. In this case, their wave-induced hull girder loads may be defined in association with benign conditions which represent similar environments to those of trading ships but reflecting site-specific metocean data.
