Hot Tapping on the Norwegian Continental Shelf

摘要

This paper summarises the experiences from the first hot tap on the Norwegian continental shelf and recommendations for future hot tap operations in the Norwegian sector. The work was carried out in accordance with the latest standards, Rules and Regulations issued by Statoil, Det Norske Veritas(DNV) and Norwegian Petroleum directorate(NPD). The "Safety First" policy of Statoil and Stolt Rockwater Joint Venture resulted in the development of new equipment and methods including carrying out parts of the offshore operation diverless. This is an essential issue for further developments to completely diverless hot taps. The hot tap connection solution has high potential for future utilization of pipeline networks, particularly with reference to the favourable impact on the economics and environmental advantages.
