Ultra-Deepwater Subsea Separation and Processing and Disposal of Produced Water at Seabed - RPSEA

Abstract

Although discharging produced water to the ambient seawater from topside is standard practice in the industry and with proven technology, several obstacles must be overcome to do this subsea at the seabed. Today’s topside technologies are meeting discharge criteria set forth by the toughest regulators around the world and studies show that the marine life is not adversely affected by these practices.

No known subsea production system has ever used any form of the typical produced water treatment technologies on topside offshore facilities, anywhere, throughout the world.

However, after a long review of the top processes and technologies being used in the industry today, subsea processing of produce water and discharge to the seabed should be achievable with development and qualification of technology in the next 3-5 years.
