ProTek® Fire & Blast Walls and Cladding
ProTek® Fire & Blast Wall and Cladding products are certified by Det Norske Veritas (DNV) and are commonly used on offshore platforms and FPSO’s where space is always a constraint and there is a need to separate high risk process areas from lower risk accommodation areas.
Flat or moulded ProTek® composite panels which are designed to be bolted to a secondary steel structure, are used to protect steel beams and columns, this forms a sealed fire / blast wall that resists fire and blast loadings. ProTek® composite panels are also gas and water tight from the effects of hydrocarbon jet fire.

Solent Composite Systems deliver an engineered lightweight cladding system that is rapid to assemble, permits inspection and maintenance access and avoids the use of hazardous materials or hot work during the installation.
The design details rely upon a bolted connection because the ProTek® is manufactured from high strength composite materials that cannot be welded. It is therefore common for steel supports to be welded in place for fixing the panels, which are bolted to the steel supports to transfer the blast loads to the main platform structure.

The ProTek® panels are designed to deflect elastically under the blast load so that they are not deformed and are able to resist a hydrocarbon jet or pool fire if it occurs after the blast. The blast load is absorbed by the panels and transferred to the bolted ends where the panel fixings resist the bending and shear loading and transfer the load into the main platform structure. The fixings are also designed to restrain the panels immediately after the blast overpressure. Following the explosion the resultant air movement generates a smaller negative suction load that pulls the panels away from the wall putting the bolts into tension.
The connection details are calculated for every application and form part of any engineering or certification report that is produced for a ProTek® fire and blast wall.
Fixings are either galvanised high strength steel or 316 stainless steel.
