... the drillship's hoisting equipment. A fully coupled fluid-structure simulation model is used to predict perforating shock loads. Before every perforating job, the operator evaluates the peak transient loads on the tubing string and heave compensator, and decides on the best strategy to prevent gunshock-related...

... that are designed to save time and/or increase efficiency and/or enhance onboard safety. These include the drill tower's dual drawworks eliminating slip-cut procedures, the passive and active heave compensation on the drawworks, and the splittable blocks. The latter allow increasing the block speed for lighter...
