Abstract
The Intelligent Well Interface Standard (IWIS) panel published Recommended Practice IWIS RP-AI in October 2007 after 10 years of work and meetings, and IWIS is now closed. This paper will address FMC experience of implementing IWIS in Subsea Control Systems. The practical use of the Recommended Practice, the specific requirements, the constraints and the gaps are illustrated with examples of actual system configurations and field experience. Subsea Instrument Interface Standardization (SIIS) activities have been running in parallel with IWIS and complementing IWIS. Some of the IWIS gaps will be closed as part of SIIS and are presented with description of proposed recommendations. Practical use of SIIS and current gaps are illustrated with examples of actual system configurations and field experience. Subsea Fiber Optical Monitoring (SEAFOM) is also running in parallel with SIIS and FMC has actively participated in IWIS, SIIS and SEAFOM since the beginning. Some of the benefits of participation together with some lessons learned are presented.
