The current deep offshore trend (DOT) presents new oil and gas discovery opportunities with commercial quantities. This has resulted in new architectures and technology developments on subsea hardwares, FPSO or Platform construction and new control systems to meet the challenges associated with these emerging deepwater field developments. The overall impact of revolutionizing subsea technology developments is that legacy system becomes obsolete and proves challenging for ageing fields. This is a significant problem facing offshore Operators as many are discovering that they are unable to execute like-to-like replacement of failed equipment as they are no longer supported in the market. This poses a very serious challenge to system availability during component or equipment failure. Shut-in-time is extended which implies loss of production and in some extreme cases, resulting in complete failure of asset. Therefore, this have necessitated the need for obsolescence solutions to enable the integration of legacy systems with future proof systems in realising value of assets and thus reduce the occurrence of obsolescence or its impact on subsea production facilities. The present paper focuses on the strategy to implement life cycle obsolescence management to bridge the gaps on existing brown field development and future proof green field development in the deep offshore industry.
