One of the world's biggest energy companies has been handed a six-figure fine after corroding pipework at its former site in Fife resulted in several gas leaks of highly flammable hydrocarbons.
Our inspectors carried out a routine visit to the natural gas processing plant being operated by ExxonMobil Chemical Limited at Mossmorran.
They found the company’s arrangements for the inspection of insulated pipework were not adequate and resulted in five known leaks of extremely flammable hydrocarbons.
After sentencing, HSE inspector Lindsey Stein said:
“At a site run by one of the biggest energy companies in the world, subject to the strictest controls, and processing high volumes of hazardous material, what our inspectors found beggars belief.
“The failure of ExxonMobil to properly inspect insulated pipework led to five separate leaks of highly flammable hydrocarbons, and while none of these leaks resulted in a catastrophic event, this was down to good fortune rather than good management.
"The arrangements in place to detect and prevent corrosion were woefully inadequate, and the consequences could have been far more serious."
