Service – Seawater Intake & Brine Outfall Systems


EPCM offers design and turnkey services for seawater intake and brine outfall systems. Our team has been involved with some of the most challenging and largest systems on the African coast.

Our team can assist from metocean modelling right through to fabrication and installation/construction of the nearshore infrastructure required.
