The UK subsidiary of ConocoPhillips explores for oil and natural gas. It produces and transports crude oil, natural gas and bitumen. It is the largest company of its kind in the world and had been operating in the United Kingdom for around 40 years.
The company solely operated and part owned the Lincolnshire Offshore Gas Gathering System (LOGGS) installation in the North Sea. The complex collects gas from its own well and from satellite platforms and subsea centres. Its main function is to compress the gas from the subsea wells so that it can be transported by pipeline to its terminal on the Lincolnshire coast.
Starting at the end of November 2012, there were three gas release incidents on the LOGGS platform during maintenance work to a defective pressure control valve on the fuel gas supply to a turbine.
Most of the gas from the first two releases and all of the gas from the third release vented safely. However, 603 kilograms of gas (out the approximately nine tonnes vented during the first pair of releases) spilled uncontrolled into the turbine hall at a dangerous proximity to the 66 people working on the platform at the time.
At a hearing in December 2015, ConocoPhillips (UK) Ltd pleaded guilty to three offences involving contraventions of requirements imposed under regulations to which the Health and Safety at Work etc Act 1974 applies. The judge imposed a fine of £1 million on each of the three breaches and ordered the defendant to pay over £159,000 towards the costs of the prosecution.
At the appeal hearing, Lord Justice Treacy dismissed the appeal made by ConocoPhillips (UK) Ltd.
He told that court that ConocoPhillips (UK) Ltd had fallen short of appropriate standards and the case was one of high culpability.
He outlined a serious and systemic failure to address risks to health and safety, both in the permit to work process and in the vital systems that had persisted over a period of time.
Dismissing the appeal, Lord Justice Treacy said, “The risk involved was foreseeable and significant. If the gas had ignited the risk to personnel of death or serious injury was extremely high. At least seven personnel had been put at extreme risk with a further five at particularly high risk. However, all 66 occupants of the platform had been put at significant risk. The failures represented by counts two and three amplified and perpetuated the failure to provide a safe system of work reflected in count one. The applicant fell markedly short of a reasonably practicable standard for a safe system of work. There had been multiple failures and omissions in the permit to work system and these failures had extended over some months.”
