ENERGY TRANSITION OUTLOOK 2021

CASE STUDY: SHELL

Taking action today to reduce the carbon footprint of assets

The Gannet platform has been processing oil and gas via subsea tie- backs in the Central North Sea since 1993. Processing equipment on the platform, such as compressors and pumps, were designed for the initial operating conditions. Over time, as production has declined, the capacity of some equipment has become too big for current requirements. By re-wheeling machinery, Shell has been able to re- size equipment to ensure that only the energy that is required for today’s operating conditions is used. There are added benefits in that surrounding equipment and piping can be retained, thus saving costs and downtime. During the 2021 turnaround on Gannet two new compressor bundles were installed to great effect; reducing the power demand on their motor drives and in turn lowering the load requirement on the platform power generation packages. This reduces total platform CO 2 emissions by 25% - with potential to go further, and give significant savings through reduced fuel gas usage.
