The main purpose of the study is to ensure whether safety systems of an offshore drilling platform maintain their integrity and perform their duty under credible accident scenarios. This assurance can be completed via reliability and availability analysis of the systems, verifying the design outcomes and recommending design and operational changes. It is envisaged that only critical safety systems will be analyzed in this study. The scope is limited to determining the reliability and availability for continuous systems, and only the reliability, often represented probability of failure on demand (PFD), for stand-by systems. Qualitative analysis is to be carried out to identify each failure mode and the sequence of events associated with it for the seven critical safety systems within the scope. Based on the result of qualitative analysis, failure scenarios are logically constructed to comprise of basic events and failure effects through fault tree analysis (FTA). The failure data will be taken from generic references such as the offshore reliability data handbook (OREDA). |
