Avoiding Rapid Gas Decompression (RGD) Damage

All seals degrade and deform over time depending on the material, operating environment and installation design stresses.

Damage caused by RGD occurs when seals that have been exposed to gases at elevated pressures are suddenly depressurised. Gas, which has migrated into the elastomer matrix, attempts to turn from a liquid to a gas within the small voids inside the seal. This induces high internal stresses that can lead to damage ranging from fatigue cracking and surface blistering to multiple fracturing of the seal resulting in total containment failure.

These guidelines, commissioned by HSE and produced by BHR Group, aim to help design and operations engineers in the oil majors, equipment suppliers, seal manufacturing companies and engineering contractors to identify areas of concern and avoid costly and hazardous failures.

Contract Cutting with Waterjets
Many industries are finding that waterjets can be an ideal solution to a wide range of problems. BHR Group's DIAJET abrasive waterjet cold cutting equipment has been proven for remote cutting of complex materials in highly hazardous zones. These include:

• Offshore in the North Sea
• Offshore in the Indian Ocean
• Decommissioning explosives for the British Army
• Bomb disposal in Cambodia
• Bridge Repairs in NW England
• Fire Fighting across the World

Biodiesel Breakthroughs
BHR Biofuels, a company formed by former BHR Group staff to develop and exploit BHR Group's mixing technology in the manufacture of biodiesel products, has developed ground-breaking technology in cost-effective biodiesel production.
