| Abstract: | In this paper, new mathematic expressions for encounter sea wave power spectrum and encounter wave slope spectrum are developed. Three methods of frequency in part, energy in part and rational power spectrum are introduced for establishing random wave model. Simulation and analysis are carried out for the method of energy in part. These can be used further in researching ship furnishment, robots working on the ship, work platform in the sea and the control of ship motion in seaway. |
| Keywords: | Encounter frequency Sea wave model Encounter spectrum Encounter wave slope spectrum Simulation |
