At present,China's offshore wind power operation and maintenance vessels are still dominated by traditional steel low-speed crew transfer vessels(CTVs).Influenced by the seakeeping and berthing ability,the annual operation time is short.With the rapid development of offshore wind power from coastal to offshore and far-reaching sea,the offshore distance is getting farther and farther,and the professional requirements for offshore wind power CTVs are getting higher and higher.The hull line design also need to develop towards the direction of high speed,high seakeeping and high comfort.This paper will introduce the main hull line design elements of high speed catamaran offshore wind power CTVs at home and abroad and their comparison,for reference of ship type research and development.
