| Seakeeping |
 FutureShip uses state-of-the-art seakeeping tools to simulate the seakeeping behavior of your vessel to predict the added resistance in waves, which is an important criterion for many vessels operating in seaways.
Based on the wave spectrum, heading and vessel speed the response amplitude operators (RAOs), relative and absolute motions, velocities and accelerations are calculated in the frequency domain and describe the behavior of your vessel. These results can be utilized for structural considerations and provide important information about likely motion sickness incident levels. The added mass is also derived and the added resistance in waves can be approximated from the analysis. In more advanced time domain simulations the steerability and maneuverability of a vessel in a seaway can be assessed which provides a helpful insight into the best operation of your vessel in heavy seas. Detailed input for structural calculations can be obtained from the simulation including dynamic loads due to pressure forces on the hull. Advanced seakeeping simulations are particularly relevant for the design of high speed marine craft where significant slamming occurs and high decelerations cause significant peak stresses. The main types of seakeeping simulations conducted by FutureShip are: frequency domain motion prediction of vessels in seaways (motion sickness incident level prediction, input for structural considerations, added mass prediction, added resistance in waves approximation) and time domain steerability and maneuverability assessment of vessels in seaways (operational criteria in heavy seas, detailed input for structural calculations, slamming and associated peak stresses, realistic added resistance in waves prediction). |
