Abstract

The paper describes the ongoing work, overall approach and process used to develop a deepwater subsea well intervention control system using structured risk and reliability principles and hardware based upon remotely operated vehicle (ROV) control technology. It discusses the selection of IEC61508 and IEC61511 as the governing standards for development of the controls architecture and certification of this deepwater well control system. It also presents the challenges that have to be addressed when using ROV hardware for well control and describes the methods implemented to overcome system deficiencies. The methods used are currently being vigorously applied throughout the control system’s development stage to insure the entire control system and not just its components, will be highly reliable, manufactured, tested and certified in accordance with the principles of IEC60508/61511 to a Safety Integrity Level of 2 (SIL 2).
