The Office of Pipeline Safety (OPS) is issuing this advisory to gas distribution pipeline system operators. Operators should examine the shut-off valves controlling gas service to permanently moored vessels (PMV) and ensure that gas service can be quickly shut down, if necessary, even during high-water conditions. In addition, operators should review their operations and maintenance manual and their emergency response manual to ensure that procedures are in place to successfully shut down the flow of gas to PMVs when necessary, including during high-water conditions.
