SAINT MAURICE, France -- MODEC Offshore Production Systems has awarded VWS Westgarth a multi-million dollar contract for the PSVM FPSO project on the PSVM (Plutão, Saturno, Vênus, and Marte) field development in block 31 Angola.

The award is for the supply of a water treatment package comprising pre-treatment and seawater sulphate removal (SRP) systems with a capacity of 31,800 cu m/d (200,000 b/d of water. Also included within the scope is an integrated seawater reverse osmosis (SWRO) system for process wash water sized at 20,000 b/d of water.

The SRP is designed to remove sulphates and other divalent ions from injection water to enhance oil recovery using Dow/Filmtec SR90 membranes. The removal of these ions reduces the tendency of barium sulphate and strontium sulphate scale to form in the reservoir. The wash water is used in the crude oil desalting process.
