The Background.

Booth Welsh has worked together with VWS Westgarth on Seawater Treatment and Desalination Plants, over many years, developing and supporting standardised control solutions for their processes. These have typically been deployed on offshore production platforms and Floating, Production, Storage & Offloading (FPSO) vessels off-shore in the UK, Denmark, South America and Africa. We have additionally provided DCS systems for the automation of large scale desalination plants in the Middle East
