Introduction  In recent years, China has put into operation a large number of offshore booster stations and accumulated rich experience in the construction and operation of offshore booster stations. Based on these experiences, it is found that the current design of offshore booster stations has certain problems, such as relatively simple analysis of operation mode, general load of air conditioning power supply in important equipment rooms, the "unattended" design concept of offshore booster stations does not conform to reality, and inadequate consideration of environmental protection requirements. The design of offshore booster station still has new optimization space.

  Method  The experience feedback of several offshore wind farms in the construction and operation stage in recent years were analyzed and the relevant of standards at home and abroad was studied.

  Result  Design optimization suggestions are put forward for the operation mode, HVAC load classification of important equipment rooms, personnel duty form of offshore booster station.

  Conclusion  The design optimization suggestions of offshore booster station summarized in this paper can be used as a reference for subsequent design of new offshore booster station.
