Sable Offshore Energy Project to Reduce Output Due to Maintenance

Sable Offshore Energy Project to Reduce Output due to Maintenance

Sable Offshore Energy Project (Sable) offshore Canada will undergo a planned reduction in operation beginning October 25, 2013, Maritimes & Northeast Pipeline, L.L.C. has informed.

Sable anticipates it will return to full operation beginning November 25, 2013. During this reduction in operation, Sable anticipates only 125,000 Dth /d (125 million cubic feet) will be available from Sable to flow on the Maritimes U.S. (MNUS) pipeline system.

“Shippers should contact Sable with any further information in regards to this outage. M&N recommends shippers contact their gas suppliers to confirm alternate supply arrangements if necessary,” M&N said.

The Chronicle Herald, the largest newspaper company in Nova Scotia, quoted the ExxonMobil spokesman Merle MacIsaac who explained that the work, at the Venture offshore field, involves replacing a small portion of the flow line that connects Venture and South Venture to the central Thebaud processing platform.

“The section of line that needs to be replaced is less than 50 metres long”, MacIsaac told The Chronicle Herald.

The Sable Offshore Energy Project (SOEP) involves the development of five natural gas fields near Sable Island which is located approximately 225 km off the east coast of Nova Scotia. The six fields are: Venture, South Venture, Thebaud, North Triumph, Glenelg and Alma. Together, these fields contain an estimated 85 billion cubic metres (3 TCF) of recoverable gas reserves and 11.9 million cubic metres (74.8 MMbbl) of condensate.

The project is divided into two ‘tiers’ of offshore development. The first tier was completed in December 1999 and involved the development of the Thebaud, North Triumph, and Venture fields, as well as the construction of three offshore platforms, an onshore gas plant and an onshore fractionation plant. Gas production begun on December 31, 1999. Alma, the first Tier II platform came on stream in late 2003 while production from South Venture, the second field, started late in 2004. In 2006, the compression platform was set up at the Thebaud complex.

SOEP is managed by ExxonMobil Canada Ltd. with its partners Shell Canada Limited, Imperial Oil Resources Limited, Pengrowth Corporation, and Mosbacher Operating Ltd.
