Abstract: With the increasing technical requirements for the structural safety of offshore facilities and the rapid development of digital technology, structural health monitoring technology is becoming more widely used in offshore facility structures for monitoring the safety of the structure and ensuring the safety of the facilities. At present, the application of digital twins technology on offshore facilities is emerging, and  the offshore facility structure monitoring system has not formed a mature technical standard so far. This paper studied the standards  of offshore facility structure monitoring system, analyze d the applicability of monitoring system design, manufacturing, installation, commissioning and inspection standards, and provided  technical support for the engineering application of offshore facility structure monitoring systems.

Key words: offshore facilities; monitoring systems, Digital twins, standard applicability
