Pressurized Welding Enclosures - Welding habitats - Pressurized Habitats - SafeHouse Habitats

SafeHouse habitats pressurized welding enclosures provide an excellent engineering solution in managing and controlling the risks associated with carrying out hot work in areas classified as hazardous. The pressurized habitat means the positive pressure inside the welding habitat prevents and air or gas from outside getting into the welding enclosure.

Pressurized Welding Enclosure Benefits

The principal benefit that SafeHouse Habitats will deliver to any project is the speed of installation, whether it be a small standard cube shape or a larger habitat. 1 engineer can install a small habitat. If the project scope includes a requirement for a number of different habitats to cover different work faces the habitats can be dismantled and re-erected as the work progresses.
This feature delivers significant benefits to the project schedule while minimising the manpower allocation and the offshore accommodation requirement.

Typically 2 or 3 pressurized habitats are supplied to be recycled around 9 or 10 different applications, this highlights the versatility of the habitat that is a consequence of the modular panel arrangement.
The package is very light, the weight if a 2m2 package is only 92 kgs.all of the component parts can be easily lifted and carried by one man reducing the risk of manual handling injuries, there is also the possibility of transporting the habitat by helicopter should the requirement merit this type of arrangement in the event of a failure of critical equipment or a similar unplanned event.

Pressurized Habitat for Hot Work - Welding Enclosure Applications

The Safe House Habitat is made from fire retardant panels that easily fit together to provide a pressurized environment that can prevent the need to shutdown production. It is a stand-alone system not requiring tie-in to vessel gas detection or control systems. It is flexible to suit all applications, pipe/structural repairs, inspections and intrusive investigations. It is designed to provide a safe module in which hot work can be safely executed while the platform or plant is live and designed in such a way to be sealed around pipe work and equipment.

The SafeHouse pressurised habitat has been used for a number of different applications where there is a requirement to eliminate or reduce risk to a manageable level for the performance of all types of hot work.
The habitats are used for the complete range of offshore works, for example:

• Installation of new pipe work for Brownfield developments.

• Installation of new structural supports for platform upgrades.

• Repair of plant equipment, crane booms or damaged pipe work.

Positive Pressure Welding Enclosure Features

Among the unique features contained within the package you will find the following:

The principal components are Modular Panels fabricated from high specification flame retardant fabric, the panels are zipped together to create the required size and shape of habitat, the internal seams are lined with Velcro strips to minimise pressure loss. The inflated habitat can form most shapes, this is particularly important where the work area is within a confined space or where there are restrictions preventing the installation of a standard cube or box shape.

A habitat structure of different sizes can be created by zipping together different panels if the application requires a 6m long x 4m wide x 2m high habitat, the only limitation on the size of the habitat is the availability of sufficient air to inflate and maintain positive pressure.
Other dimensioned or special panels can be manufactured if it is the case that the standard panels are unsuitable for the application.
The habitat is largely self supporting when inflated however it is advised to anchor the roof and wall panels to scaffolding or steelwork, this is achieved by fastenings secured to the cleats on the panels. When the habitat is deflated it will not collapse and fall to the deck.

Welding Enclosure Operation

The habitat is inflated by means of compressed air supplied from a compressor or from the platform’s plant air utilities system; the requirement is less than 1 bar.
The air delivered into the habitat environment is of breathing quality; there is also an exhaust facility to remove welding or other harmful fumes.
