Due to the complexity of ocean environmental conditions and non-linear structural responses, there are many uncertainties in establishing design of deep-water floating platforms. Traditional hydrodynamic analysis and model test, till now, still can’t provide the long-term safety and reliability for floating structure in harsh environments. Prototype test, as a full-scale experimental method, is carried out on in-service platforms to obtain the real response without simplification and hypothesis. The obtained data can be used not only to reduce uncertainties, but also to verify and further improve design specifications.

In this paper, the full-scale measurement technique for floating platforms is discussed. Four monitoring subsystems are built up related to different characteristics of data collection in-service platform. Individual Remote Monitoring System (IRMS) is established to perform the remote communication between platform and land. The full monitoring system is carried out on a FPS in South China Sea, which supported by a joint industry project (JIP). Some useful monitoring results are presented at last to demonstrate the reliability of the whole monitoring systems.
