When every square inch can be measured in terms of thousands of dollars over the lifetime of a platform, blast and fire protection that simply takes up less space is a huge benefit. In contrast, ContraBlast is a fully-integrated pre-formed fire and blast protection panel that is light in weight and offers excellent performance, in a small footprint.
Advanced Structural Analysis
The ContraBlast panel system offers a very versatile and effective solution in meeting the challenge of the topside environment. ContraBlast offers a blast rating up to 1. Unlike many competitor systems, there is zero degradation of PFP passive fire protection after the blast event. Back face temperatures remain low for a significantly longer period than with more conventional blast wall options, when tested both in extremely aggressive jet fire and in hydrocarbon pool fire situations. This performance earns ContraBlast ratings of up to JF and H, to tick the boxes for specifiers.

A further advantage of ContraBlast is that it is dry fit, eliminating the need for welding, which is obviously a major plus-point in the high-risk environment of an oil platform. The mm x mm panels can be combined using their tongue and groove joints for coverage of larger areas, forming a completely sealed blast and fire resistant wall system. Assessment of gas explosion loads is used as a basis for weight optimisation of topside designs built to reduce gas explosion hazards.

Jacket The jacket is the foundation of a fixed platform and is exposed to a severe corrosive environment including waves, ice, UV radiation, wet and dry cycles.
go to link Topside structure The topside structure is exposed to severe UV radiation, and a topcoat may soon lose gloss and colour to the extent that refurbishment is desired. The answer to this is the super durable topcoat Hardtop Optima - based on the latest polysiloxane technology and with a good HSE profile.
