Action 13:
5.7.2 Performance
The FSA reviewed the performance of the SIS over the 18 months that it has been in the
ownership of Local Fuel, the following were considered:
Actual Activations: (Demand on System)
No activations have occurred.
Spurious Trips:
No spurious trips have occurred.
Random Hardware Failure:
No hardware failures have occurred.
Systematic Capability and Systematic Failures:
No systematic failures have been identified.
Operating Difficulties:
Local Fuel plc have taken over the operation of the Terminal and the SIS with no handover
from Valero. They have now operated the system for 18 months and have had no difficulty or
problems with the system.
Interface with BPCS:
The import valve is opened and closed via the HMI system. However, the BPCS can not
interfere with the operation of the SIS system as this is performed on the dedicated hardwired
input to the valve.
