An LPG supplier is making a “necessary upgrade” after a weakness was identified in safety systems at Mossmorran gas plant in Fife.
Avanti Gas Ltd was issued with an improvement notice by the Health and Safety Executive for “failure to demonstrate that all measures necessary have been taken to prevent major accidents and limit their consequences for human health”.
The improvement notice states that the firm, which has a loading terminal at the gas plant, had not demonstrated that instrumented safety systems of undefined safety integrity level, which have been installed to provide risk reduction against major accident hazards associated with bulk LPG storage vessel V201, are being adequately managed.
This was specifically in regard to a bulk LPG storage vessel branded V201.
A spokesman for the company said: “AvantiGas and its predecessor Shell have an exemplary, industry-leading, safety record at Mossmorran and we have operated the site for 25 years without any major accident. This is a direct result of the rigour of our safety procedures and the reliability of our technology.
“In the opinion of the HSE Inspector, a weakness in the management of our low-integrity safety systems was identified.
“This refers to the way in which we qualify and manage sensors, logic solvers and actuators used to automate the plant.
“We will of course be making any necessary upgrade to remedy this as quickly as possible. The upgrade will mainly involve the generation of documentation to support this operation.
“The improvement notice does not mean that the HSE has found anything that could be identified as dangerous practice.”
