The objective of this article is to summarize the main requirements of the permit, identify changes from the previous permit, and call out edits between the draft and final issue of the permit as these pertain to the discharge of produced waters and other treated waters from offshore production and water injection facilities.

These work effectively on dispersed, O&G; however, these systems do not effectively remove water soluble organics (WSOs). Where WSOs exist in concentrations greater than 29 mg/l, conventional produced water treating systems cannot achieve GoM overboard discharge limits.

Methanol (MeOH) is widely used in multiple applications in the offshore oil and gas industry.

This GATEKEEPER discusses various options available for ballast water tank treatment in these circumstances.

Induced Gas Flotation (IGF) has been used for Produced Water (PW) treatment for decades. The roots of flotation technology are in mining, where it has been used to enrich metal ores since the late 1800’s.
