Subsea Controls Obsolescence

Samphire Subsea Case Study

A Northern North Sea asset has a Control System of early 90’s design. The asset end of field life had extended significantly and the control system was now obsolete.

The OEM could no longer guarantee support to the system and although the client had spares for some of the key components there was a real business risk from failure.

Samphire was engaged to support the review of the system risks and assess the alternative service support options from suppliers focused on the mature asset market.

The options were quite limited for the topsides MCS apart from replacing the complete top end control system. Given the nature of the alternative suppliers an assessment was undertaken to highlight all key issues associated with the change and eventually a smaller dynamic contractor focused on the mature asset market was selected for the replacement top end control system.

Relevant mitigations were progressed to ensure the alternative solution was robust and did not expose the business to further risks. Ultimately this represented a good solution for the asset, the provision of a functional system at significantly less cost.
