SafeZone Positive Pressure Habitats

We provide companies in the African Oil & Gas Industry with both ATEX and IECEX certified positive pressure habitats for use in hazardous areas. OGL supplies Pressurized Habitats and Hot Work Safe Enclosures, capable of maintaining a positive pressure environment and extracting the airborne hazards while greatly reducing the risk of fire and oil or gas explosions and allowing hot works to be performed safely.

Industrial Applications

Oil & Gas Welding Application (Onshore / Offshore)

The Bureau of Safety and Environmental Enforcement (BSEE) has a current regulation for offshore operators that prohibits welding within 10 feet of pressurized process equipment or the perimeter of the well bay unless the platform is shut-in. BSEE will allow a waiver of this regulation if a PWE is used, given the appropriate notifications to the agency are made. Once approval is granted a PWE can be constructed and hot work is allowed in classified areas without having to shut down production operations.

Chemical Plants, Refineries, and other Onshore Locations

PWE’s are used in chemical plants, refineries, and other onshore locations to keep the facility running during hot work operations. They can be used for any emergency repair that needs to be made in between turnarounds or sensitive areas where additional safety barriers are needed. Enclosures are custom built to size and can be very large in order to encapsulate huge vessels if needed. PWE’s can also be used when welding within 100’ of a loading dock, where otherwise hot work is restricted to specific days. Approvals need to be granted by the Coast Guard and a hot work permit addendum would be issued.

Encapsulate and Isolate Hydrocarbon

An enclosure can be installed to encapsulate and isolate hydrocarbon areas such as well heads, valves, and flanges where the potential for hydrocarbon release exists. The PWE process is reversed to create a negative pressure around the known hazard, and hot work operations can continue in the nearby vicinity of an existing or potential leak.

Global Experts and Operational Capacity

We partner with the leading experts in the PWE Industry that use a modular system that can create a safe working environment around the most complex areas. Intricate pipework, valves and beams can all be accommodated whilst allowing full access in a completely sealed area.

Our highly trained operatives ensure that the habitats are assembled to the ATEX and IECEX standards, for safe use in hazardous zones (1 and 2). In addition, we can provide many of the services that you might require within the habitat itself.

Our sophisticated system delivers everything you need to set up a safe environment in one box: no additional modules, units or add-ons. It is portable, light and cost effective to transport, as well as reducing set up time.

We can provide you with an all-encompassing service solutions within the habitat including welding, plating, pipe fitting, corrosion management, reducing the cost and time spent performing time critical integrity activities. Our multi-discipline teams will perform all the work helping you to cut spending with no compromise to safety.
