Abstract: The traditional "two tickets" management mechanism is unavailable for the safety requirements for onsite operators and the equipment operation and maintenance quality control requirements at the offshore windfarms. Therefore, a mobile "two tickets" management system suitable for offshore windpower operation and maintenance activities has been developed based on internet communication, multimedia and other technologies,which settles the iproblems involving personnel review, process supervision, and technical consultation encountered in the practices of safety production, and improves the modernized management level of offshore wind power enterprises.
