Preliminary Chart of Drill Ship Operability Considering Moon Pool Sloshing Effects

The safety and feasibility of a drill ship operation can be synthesized in a chart of safety zones, which can ease taking fast decisions given a sea state. The authors propose a preliminary chart, based on a collection of parameters, including RAO, structure loads, and internal characteristics as DPS and moon pool specifications. The calculations were made for a Series 60 model modified to attend the geometric characteristics of real drill ships. The influence of moon pool’s sloshing effects and hole’s shape and location are analyzed through potential velocity model with free surface damping, and varying the incident wave’s encounter angle.
