The Safehouse pressurised habitat system has been used successfully by the Upstream and Downstream Oil & Gas Industry for many years, the safe deployment has allowed naked flame and other hot work to be carried out without the need for a Production Shutdown.

The principal components are Modular Panels fabricated from high specification flame retardant and fire proof fabric, the panels are zipped together to create the required size and shape of the habitat, the internal seams are lined with Velcro strips to minimise pressure loss.

Features

ATEX 95



The panel design allows for construction materials and equipment for example pipe spools or steelwork to be brought in and out of the habitat without need to completely dismantle it; one side can be simply unzipped or the roof panel can be rolled back to allow the crane to drop pipe spools in situ.

The package of modular panels is completed by 2 different types of penetration panels, firstly there is the standard penetration panel which is designed to accept single spools or pieces or equipment up to a diameter of 42 inches, these panels are particularly suited for applications like riser connections or large bore hydrocarbon lines, all of the panels are interchangeable allowing them to be used on the floor or the roof or through the side walls.
