The problem of interest in this work is the numerical simulation of a ship maneuvering in a seaway. A key challenge of this problem is the time-scale disparity between the high-frequency seakeeping response and the slowly varying maneuvering motion, both of which are coupled with the interaction of the hull, propeller, and rudder. The time-scale disparity becomes extreme when the rotation of the propeller is resolved in a time-accurate manner, requiring small time-step increments relative to the seakeeping and, in particular, the maneuvering time scales. Our novel approach to the maneuvering-in-waves problem is a hybrid simulation method that combines a fast-running computational fluid dynamics solver, a semi-empirical propulsion model, and a higher-order boundary element method. The hybrid simulation method is compared to a new numerical benchmark for the Duisburg Test Case Hull turning in waves.
