ENVIROUNIT Offshore Slop Water Treatment System

Overview Library

Portable ENVIROUNIT units for treating drilling wastes offshore

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

The ENVIROUNIT offshore slop water treatment system provides a rig-based, modular solution for treating and recycling slop water. The proprietary and compact four-step treatment process reduces overall waste volume by more than 90% while simplifying logistics and saving significant time and costs compared with conventional methods.

ENVIROUNIT system benefits

  • Reduces offshore drilling waste stream by up to 90%
  • Minimizes transportation requirements
  • Recycles and enables reuse of oil- and synthetic-base drilling fluids
  • Lowers landfill disposal requirements and liabilities
  • Minimizes personnel requirements
  • Allows complete waste-stream traceability
  • Reduces supply-boat downtime for tank cleaning after slop water transport and eliminates waste production from cleaning
