The current Goliat FPSO design is based upon wet gas reinjection (no water removal from the gas).
Client: Eni Norge (now Vår Energi)
Project: Goliat FPSO DGES FEED Study
Date: May 2012 – May 2013
In order to export the gas solution either by CNG (Compressed Natural Gas) vessels (ships) or other gas export concepts it is required to dehydrate the full gas processing capacity of 4 million standard cubic meters of natural gas per day at approximately 45 bars.
In addition the alternative pipeline export solutions to Snøhvit and the impact of different routing of export systems to various riser locations for gas export to be evaluated.
Scope of Work:
- Develop and verify dehydration concept and perform concept optimization.
- Develop EPCI execution plan with schedules and estimates
- Development of strategy for lifting and installation
- Integration and hook up of the new facilities into the existing FPSO design, including gas export line.
- Preparations for procurement of packages.
The study will comprise the following:
- Gas dehydration system (dehydration towers and TEG regeneration unit). Additional weight: 250-300 T
- Gas export system: metering, dry gas export flow line, possibly an additional riser or a subsea split.
Added value: Environmental friendly solutions,
