LR: reducing risk from hydrocarbon leaks

Lloyd’s Register Consulting has introduced its first phase of its latest JIP aimed at resolving a long-term industry issue that could save the industry billions of dollars in costly downtime, possible injury claims and damage to the environment.
“Ignition of hydrocarbon leaks in gas turbines is a critical issue for oil and gas operators,” says Ingar Fossan from the Consulting business of Lloyd’s Register. “Findings from this JIP will lead to safer design of new installations, reduction in risk of future incidents on existing infrastructure, leading to tangible cost reduction.”
The turbine enclosures and generator rooms used in the oil and gas industry are high risk areas because of the combination of very high temperatures, moving parts, fuel, and lubricants.
Flammable gas included in the intake air of a gas turbine is a widely-known and potential source of ignition. However, the residual risk is still not adequately understood, and more detailed understanding of the potential ignition mechanism is necessary to find the best possible way to design the ignition control parameters for gas turbine equipment. It is based on the main conclusion from the MISOF report (Modelling of Ignition Sources on Offshore oil and gas Facilities) issued by Lloyd’s Register on behalf of the Norwegian Oil and Gas Association.
Fossan added: “The JIP brings together technical and operational expertise on gas turbines to collaborate on data gathering and advanced modelling of potential accidental scenarios. Considering the complexity of the various operating scenarios and differences in how gas turbine machinery are designed and manufactured, the JIP starts with an initial assessment and agreement with JIP partners on the primary issues and areas of investigation.”
Follow on phases of the JIP will study these issues through advanced modelling and experimental work. The JIP will run in phases with the initial phase being finalised in February 2016. The next phase will be launched in 2Q16.
