New guidance for explosion loads launched for oil and gas

Lloyd’s Register’s has released new Guidance Notes for the Calculation of Probabilistic Explosion Loads in oil and gas.

Structures and equipment that could be subjected to blast pressures need to be designed for accidental blast loading, maximising safety in offshore operations. This approach by Lloyd’s Register allows for a detailed examination and assessment through a range of probabilistic risk assessment techniques, which help companies predict possible explosion scenarios.

The new Guidance Notes for the Calculation of Probabilistic Explosion Loads are recommended to be used alongside the Lloyd’s Register’s Rules for Offshore Units. These Rules provide the oil and gas industry with confidence that their assets are designed and constructed to internationally recognised standards.

According to Joar Dalheim, VP Technology at Lloyd’s Register Energy, companies can use the new Guidance Notes with the Rules for Offshore Units to simplify and streamline their design appraisal process.

Companies operating offshore can employ a wide range of measures to prevent, control and mitigate the effects of explosions. While the emphasis should always be on explosion prevention, the possible accumulation and ignition of a flammable hydrocarbon-air mix cannot always be eliminated.

The Lloyd’s Register methodology can be applied to any offshore unit at risk of gas explosion hazards. The Guidance Notes for the Calculation of Probabilistic Explosion Loads also include special guidance on handling leak scenarios involving Liquefied Natural Gas (LNG) plants, which can be caused by flashing of cryogenic liquids into the atmosphere.

The new Guidance Notes for the Calculation of Probabilistic Explosion Loads can be downloaded from the Lloyd’s Register website.
