Subsea Asset Maintenance on the NCS: On the Trends, Future Innovation, and Fitness of Life-of-Field

摘要

This paper studies the future subsea asset maintenance on the Norwegian Continental Shelf and evaluates the fitness of life-of-field. The future subsea asset maintenance is studied by analysing 15 subsea asset installation projects awarded on the Norwegian Continental Shelf in the last 10 years. The data were gathered from various reliable sources, including "FACTS 2013 - The Norwegian Petroleum Sector" published by the Ministry of Petroleum and Energy and the Norwegian Petroleum Directorate. The sources also include websites of oil and gas companies and subsea contractors, and related publications. Life-of-field refers to services offered by subsea contractors to oil and gas companies once a field has started its production. This paper uses Subsea 7's installations as a case study. The fitness of life-of-field was assessed by comparison to future subsea asset maintenance on the Norwegian Continental Shelf. The success criteria and the fitness of life-of-field services can be used by oil and gas companies and subsea contractors to better enable subsea asset maintenance to perform its role effectively in oil and gas field development.
