Abstract: As an important solution for offshore marginal oil fields,self-elevating wellhead platforms （wesu） have been deployed in the Beibu Gulf. The installation and standing modes of self-elevating wellhead platforms are different from the traditional jacket platform. Although the weather conditions in the Beibu Gulf are fully considered in the design parameters,it is still necessary to monitor the key position parameters of the platform under typhoon condition. This paper expounds the needs for data monitoring and return of a self-elevating wellhead platform in the Beibu Gulf sea area under normal production and typhoon conditions,and puts forward the monitoring and return technologies for platform pile legs,jacket support,platform swing and meteorological data,which can provide reference for typhoon prevention measures of similar to self-elevating platforms.

Key words: self-elevating wellhead platform, typhoon prevention, condition monitoring, Beidou short message, data return
