Water Stewardship
Reduces waste stream by up to 95% and enables onsite discharge of clean and fully compliant water.

Portable systems for treating drilling wastes offshore

Conventional slop water treatment methods involve shipping waste to shore for treatment and disposal. This process increases exposure to HSE risks and can still cost thousands of dollars per cubic meter of slop. Shipping to shore also requires thorough cleaning of the vessel tanks after offloading, which adds to costs and the overall volume of waste.

The ENVIROUNIT offshore slop water treatment system provides a rig-based, compact, and modular solution for treating and recycling slop water. The proprietary four-step treatment process reduces overall waste volume by more than 95% while simplifying logistics and saving considerable time and costs over conventional methods.
