- Abstract:
- The aim of the work is to describe a practical and functional method to transform a wave energy spectrum from encounter frequency domain to absolute frequency domain. An important topic in the marine engineering field is the evaluation of the directional wave spectrum from the ship’s measured motions, however, when a ship advances in a seaway any spectrum estimation is directly in to the encounter frequency domain. A transformation from the encounter domain to the absolute domain, corresponding to observations from a fixed point in the inertial system, is necessary. Several cases have been examined, for different angles between the route and the prevailing sea state, to validate the presented technique showing accurate results for all the tested cases.
