Purpose

Reduce ballast water in the gathering system, unload pipelines and the central oil treatment plant, and condition water for further treatment or injection.

Process arrangement

Simplified process diagram

The diagram identifies the principal process duties, equipment connections and product handover points. Final scope, redundancy and battery limits are established from project data.
