FERC has asked Dominion Cove Point LNG LP (DCP) to provide additional information ahead of a technical review and site inspection scheduled in June by Commission staff of its liquefied natural gas (LNG) export facility.
In a letter Wednesday, the Federal Energy Regulatory Commission asked DCP to identify, within 20 days, any changes to the design or operating conditions since the Commission's last review of the Maryland facility, which is in the last phases of construction. Such changes may have been imposed or recommended by federal, state and local regulators, as well as insurance companies.
FERC requested a current plot plan of the facility, as well as hazard detection and hazard control drawings, and piping and instrumentation diagrams. The Commission also asked DCP to "describe any abnormal operating experiences or behavior at the facility since the last review."
According to FERC, abnormalities might include rollover, geysering, cold spots on storage tanks, storage tank vibrations, leaking/inoperative isolation valves, significant equipment or instrumentation malfunctions/failures, and unscheduled maintenance or repair. It also asked DCP to cite any relative movement of the inner vessel, vapor/liquid releases, negative vacuum pressures within storage tanks, higher-than-predicted boil-off rates, and any LNG shipping problems.
Two weeks ago, DCP asked the Department of Energy (DOE) for permission to begin exporting commissioning cargos from the facility, which is on the coast of Chesapeake Bay in Lusby, MD. The company pledged to DOE that commissioning volumes, when added to volumes exported under DCP's long-term export authorizations, would not exceed 250 Bcf for any consecutive 12-month period.
Last month, DCP reported on its website that the facility is 84% complete and is expected to enter service later this year.
