4. REGULATION 18: RELIABILITY PERFORMANCE MEASURES
4.1 Estimates, Assumptions and Adjustments
For the Maui pipeline, unplanned interruptions have been counted in four ways:
-
An interruption in the supply of Maui gas into the pipeline, whether or not there was any effect on users. Figures are available up to the end of October 2006. This measure became inadequate as substantial amounts of gas from non-Maui sources became available.
-
A curtailment of a nominated shipment through the pipeline for any reason. This measure has been used since November 2006. The possible reasons for curtailment include matters outside the pipeline operator's control such as failure of a party to supply gas as scheduled, or failure of a party to take gas from the pipeline as scheduled, or force majeure events affecting pipeline delivery or off take. A curtailment may only affect some pipeline customers, with others unaffected.
-
A curtailment or interruption due to the failure of the pipeline or pipeline equipment. There have been no failures of this type in the periods reported on.
-
High pressure incidents considered are those that required curtailment to mitigate an over pressure situation.
Records kept using the different methods are not directly comparable.
