We provide innovation and solutions to minimize operators’ downtime, reduce environmental impacts and help keep you drilling.

Environmental Cleaning - NORM 

Gibson’s CHI, Trussco and Preheat wholly owned subsidiaries are environmental services leaders in the oil and gas industry. Our companies have more than 30 years of successful environmental cleaning project management. We have built an impeccable reputation for reliability and safety. Our expertise helps customers eliminate potential liabilities, ensure regulatory compliance and reduce downtime.

With facilities in all of Louisiana’s Gulf of Mexico ports, we provide a wide breadth of service capability to meet your environmental cleaning needs.

Dockside Cleaning (NORM)

Gibson’s NORM decontamination facility, located in Intracoastal City, Louisiana, provides dedicated oilfield equipment decontamination services for all production, drilling, and drilling mud-contaminated equipment, including piping and vessels. The facility is equipped with two decon slabs, a high-pressure water blasting unit used for lance tubing, a pipe cleaning unit with range III rigid lance rail (40psi and decontamination ID and OD piping from two inch to 20 inch ID and OD), and a closed-loop vacuum system. The facility’s access to road and bulkhead accommodates loading and unloading to and from land or offshore. It is open seven days a week to meet customers’ stringent NORM requirements.

  • Flex lancing
  • Fill line
  • Drain line
  • Suction/discharge line
  • Complete mud system cleaning: shakers, sand traps, ditches and tanks

Dockside Automated Cleaning (ATLANTIS)


Gibson’s Automated Land-Based Technology-Integrated System provides technologically advanced automated cleaning for supply vessels operating in the Shelf and Deepwater Gulf of Mexico. ATLANTIS uses mechanical cleaning devices for high-volume, high-pressure water flow. The ATLANTIS chemical process transforms mud into slurry for easy pumping. The ATLANTIS recycling process separates waste for environmentally efficient disposal. Our ATLANTIS facility sets a new standard in automated cleaning that is safer, more cost efficient, and environmentally sensitive.


Automated Cleaning Service (IMPACT™)

Gibson’s IMPACT system provides a safe, cost efficient, environmentally conscious alternative for tank and vessel cleaning. Our unique process takes solid buildup and removes it mechanically using the vessel’s pressure. This method allows sand and solids to settle to the vessel bottom and prevents suspension into the fluid pad. See how IMPACT works: Introducing IMPACT.

  • Mechanically removes solid build up with assistance of the vessel’s pressure. Keeping sand and solid profile at the vessel bottom prevents solids suspension into the fluid pad.
  • Induction lines introduce polished, produced fluids back into the vessel to remove solids.
  • Generates zero fluid waste.
  • Customers retain 100 percent of vessels’ function.
  • Drastically reduces exposure to Confined Space Entry hazards.
  • Increases customers’ production efficiency.

There are inherent risks associated with confined-space entry. Stringent safety guidelines can help protect employees, but cannot completely eliminate the increased risks of hazardous work environments. The IMPACT cleaning system eliminates confined-space entry exposure.


Facility maintenance can be a significant cost; shutting in production in the Gulf of Mexico can cost tens to hundreds of thousands of dollars per day. The IMPACT system is able to extract solids from all low-pressure applications, including separators, skimmers and heater treaters, without the need to shut in the production facility.

The Environment

Gibson is committed to improving environmental efficiencies and reducing environmental impacts. IMPACT mechanically removes solid waste using the vessel’s operating pressure and existing internal fluid. Induction lines reintroduce polished fluid back into the production stream. This process greatly reduces and may even eliminate fluid waste.

Mobile Cleaning (ATLANTIS-M)

The ATLANTIS-Mobile cleaning package provides technologically advanced automated cleaning for deepwater supply vessels in the Gulf of Mexico. ATLANTIS Mobile technology uses high volume, high pressure water flow to transform mud into slurry for easy pumping and separates waste for environmentally efficient disposal.

  • Level controlled safety systems
  • Cleans two liquid mud tanks and final cleans two additional tanks simultaneously
  • Reduces cleaning duration by up to 60% over conventional cleaning methods
  • Reduces confined space entry time by up to 80%
  • Reduces crew size and fatigue factor
  • Cost and environmentally efficient waste disposal
  • Self contained
  • Small dock footprint
  • Easily deployed to location

Engineered to operate safely, ATLANTIS-Mobile features level-controlled safety systems. The ATLANTIS-Mobile package reduces confined space entry time by up to 80% and reduces crew size and associated fatigue factor.


The self-contained ATLANTIS-Mobile system is able to clean two liquid mud tanks and final clean two additional tanks simultaneously. Automated cleaning reduces cleaning duration by up to 60% over conventional cleaning methods.

The Environment

Environmentally sensitive waste disposal is also cost efficient.

Pressure Washers

Light, medium or heavy duty; we have the right tools for your job.

Light Duty

Sioux cold-water pressure washers are ideal for lighter cleaning jobs such as rinsing off dirt, mud and dust. They are excellent for vehicle and grounds maintenance and cold-water cleaning applications. These units are easy to operate since they require no conventional fuels or exhausting, and very little maintenance.

High Pressure

Sioux high-pressure units are great for demolishing encrusted dirt, mud or heavy films from equipment and plant facilities. Choose from caster, wheelbarrow, skid or stationary mountings. Units are available with electric motor, gasoline engine or diesel engine. Electric cold-pressure washers can be built to explosion-proof specifications for use in hazardous areas. Units feature sealed, cast-aluminum enclosure with galvanized steel conduit. All electrical components are explosion-proof. Explosion-proof cold-pressure washers can be built to Class 1, Group C or D specifications.

Dakota Series

Sioux Dakota Series hot-water pressure washers are certified to UL 1776 and CAN/CSA-B140.M-189. They comply with OSHA 1910.399 regulations, and are third-party certified by NRTL to protect your employees, your company and yourself. Certified equipment helps protect against OSHA fines and possible litigation. The Dakota Series is approved for indoor and outdoor use, which gives you greater flexibility for all your applications. Improved coil designs allow total draining of vertical coil. Tilting coil allows easier burner adjustment and maintenance. Their high efficiency and lower fuel usage will save you money.
