Apollo won a competitive tender to perform a large life-extension project for an operator based in the North Sea. The project equated to 70,000 people hours over 2 years.
As part of that life-extension case study was an opportunity to look at each section of the FPSO individually in order to extend the life of the asset. Within that required a large controls systems review.
An independent review was completed on 18 control systems across the asset, asking the following questions:
The client was concerned about an ageing asset but still could see reservoir returns and so wanted to extend the current life expectancy of their FPSO.
In order to do so, it is vital that the assets control systems are sufficiently supported, reliable and available in line with reforecast CoP dates.
The solution was to fully review all the systems and make cases for upgrade or retention.
Due to this review, it would mean that the system was expected to operate beyond 2030. It also meant that the operator was able to save significant CAPEX costs.
By conducting an in-depth review it enabled us to advise our client with regards where they should target their investment in support of the extended operation. where they should invest their money. This was done by reviewing each system independently, identifying the system components, performing a reliability review, vulnerability review, highlighting the impact of a failure and providing options for life extension.
And for all you engineers who want more details:
The current supported life of each system needed to be understood, and a proposal for life extension beyond 2030 was to be recommended.
Apollo was able to deliver a reduction in overall CAPEX costs by only recommending system upgrades that were entirely necessary. In addition, Apollo was able to provide a more targeted plan in support of life extension. This provided the client with a better understanding of the offshore implementation and enabled them to make informed strategic decisions to ensure reliable operations beyond 2030
