LNG Facility Security: Lessons Learned From the Security Breach in Lynn, MA

A recent breach in security at an LNG facility shows the need for preparedness and vigilance. The operator discovered a breach of security at its LNG facility during routine maintenance on a gate at the side of the storage tank. Although there was no damage to the tank, intruders had broken through the gate to gain access to the tank.

Investigation revealed that the intruders had cut through the outer and
inner perimeter fences and through the locked gate and gained access to the storage tank several days before the breach was discovered. A microwave intrusion system documented the intrusions on the computer monitoring system, which should have alerted operator personnel to the intrusions. Operator personnel did not respond. In
the days following, personnel conducted several routine visual inspections of the area without noting the cuts in the fences.

Although there was also video surveillance of the perimeter, personnel did not review the tape until they investigated the breach.
