AMOG undertook a detailed study of a range of options for upgrades to a SE Asian marine terminal under 10 year and 30 year life extension scenarios. The work was undertaken in two stages with the first identifying a range of different options with the second phase undertaking a detailed concept selection study for the 3 short-listed options. 

The option study considered a range of system parameters including upstream storage, pipeline capacity, infield/offshore storage and enhanced export rates. Detailed uptime estimates of the different options were performed with the uptime model calibrated against existing metocean and offloading data (including demurrage and deferred production). The second phase undertook feasibility level studies of 3 platform/CALM Buoy repair/replacement options and developed lifecycle costs estimates for each over the two life extension scenarios. Additional studies addressing site specific issues arising from the unique conditions at site were also undertaken for both the CALM Buoy and the platform.

AMOG undertook further detailed uptime assessment studies and platform structural assessment studies as part of a Life Extension study programme. The detailed uptime assessment studies included the effects of an additional condensate stream being introduced into the existing offloading system.

AMOG then undertook detailed analysis of competing CALM Buoy mooring system design configurations to verify that the tendered designs would meet the specified performance requirements. Detailed mooring system analyses were performed for various operating and survival conditions, as well as looking at the potential impact of the local environment on system response over the 30 year life.

In addition to the CALM Buoy export system studies, AMOG undertook a programme of platform motion measurement using an accelerometer package fitted on the terminal platform. Detailed analysis of the platform acceleration response and comparison against site metocean conditions was made.
