Kent performed a concept and pre-FEED study for the Finlaggan tie-back to the Britannia platform. The study was completed in January 2017. Different options were considered including re-use of an existing separator, installing a new separator on a deck extension, adding a new module with all dedicated equipment required for Finlaggan processing.

The study scope included:

Capacity review (using in-house capacity modelling tool MeasCap) of all major topsides equipment and risers for over ten processing options.
Site survey to confirm potential equipment locations, identify potential opportunities for the project and validate expected constraints.
Development of most relevant options, including multi-discipline technical feasibility review, pros and cons analysis, and installed cost estimation to +- 50%.
Recommendation of the preferred riser for Finlaggan tie-back.
Options screening workshop with concepts scored based on a range of factors to allow client to select a single option.

The study progressed into a multi-discipline Pre-FEED study with the selected option. This included further option definition with development of PFDs, P&IDs, H&MB, equipment list, layouts, pipe routings, cost to +- 30% and project schedule estimates for the selected option. HAZID and constructability reviews were also undertaken during pre-FEED.

Added Value

Successfully completed the study in a fast track schedule by using the Kent automation tool for capacity constraints modelling (MeasCap),
Ensure appropriate decisions were made early in the study in agreement with the Client and the third Party by performing several workshops at key milestones in the project,
Generate innovative ideas to maximise asset utilisation, including the option which was eventually selected.
