Sea Robin told shippers Tuesday it must shut in the entire
system for 10-12 hours today and asked them to cut their nomination
levels by 50%. The action resulted from being informed by Texaco,
operator of the Sea Robin Processing Plant, that the plant must
halt operation to repair a leak. The event constitutes a force
majeure, Sea Robin said, and thus it declared an OFO Type 30 for
the shutdown period. The pipeline said it had contacted downstream
delivery point operators and they could not accept gas untreated by
the plant's dehydration facility.
Westcoast said it is starting pipeline integrity work today that
will last about five days and is sensitive to linepack conditions.
"Significant packing" of the system is occurring, particularly at
the McMahon, Fort Nelson and Highway plants, Westcoast said, and if
it continues there will be increased pressures in the gathering
areas. Balancing tolerances of 0% pack and 20% draft are in effect
until further notice. Westcoast noted it is limited in shedding gas
off-system while NOVA has a firm curtailment in place at the
Gordondale delivery point. In addition, Westcoast said extra gas
has been coming onto its system due to NOVA outages, but there was
no corresponding increase in deliveries.
Tennessee does not expect any service restriction during a June
14-15 pigging of the Blue Water System, but said some producers may
experience higher than normal pressures.
