9 Subsea chemical storage and injection
There are several reasons why it is of interest to store and inject chemicals subsea. As the complexity of a field increases, the umbilical will become larger, more complex, and more expensive to manufacture and deploy.
The Subsea Chemical Storage and Injection would allow to enhance and/or enable oil and gas field developments, in particular for long subsea tie-backs to surface facilities located more than tens of kilometres away, where the economics could prove to be challenging with conventional electro-hydraulic umbilical.
9.1 Subsea Chemical Storage and Injection (SCS&I) by TOTAL and Technip FMC
TOTAL and TechnipFMC have agreed to work together on the development of the SCS&I Station as part of a collaborative project. Chemicals include corrosion inhibitor, demulsifier, scale inhibitor, biocide, LDHI, methanol.
The SCSI station includes storage tanks, control system, injection pumps, flow control devices and monitoring, valves.
