Ocean waves simulation during 2001to 2010was constructed to explore the ocean waves energy in Shandong offshore by using the third-generation wave model SWAN.The validation results show the model is accurate and robust comparing with the observations.The average wave energy flux densities in Shandong offshore are almost below 2 000W/m,which are lower than the European countries and the southern coast of China.12points around Shandong offshore were analyzed from variations of wave energy flux density and other objective wave energy related factors,which show that the wave energy flux density appears an obvious rising trend due to climate change.From the comprehensive view,three areas are recommended as the priority area for the development of ocean wave energy,which are the eastern offshore of Shandong,the central area of the Bohai and the outer ocean near Penglai islands.In Chengshan eastern sea,the wave energy resource is abundant.The wave energy flux density in the winter is up to 5 000W/m.For this,the development and utilization of small and medium-sized power supply equipment or facilities are in line with reality.
