Tobago Pipeline

NGC has constructed a sub-sea natural gas pipeline from the BHP Billiton Gas Export Platform (GEP) in the Angostura Field off the north – east coast of Trinidad and south–east of Tobago to Cove Industrial Estate, Tobago. Its related Gas Receiving Facility at Cove Estate has also been recently completed.

About the Pipeline to Tobago:

• First gas was received in Tobago on 2nd November, 2012 at 5:20 pm
• Size: 12”in diameter
• Water depth: 24-92m
• Length: marine segment- 54km / land segment – 800m
• Capacity: 119 million cubic feet per day (mmcfd)
• The pipeline can supply 119 mmcfd of gas per day based on a supply pressure of 850 -900 psi (pounds per square inch) at the BHP Billiton GEP
• Purpose: Initially to supply natural gas to customers of the Cove Industrial Estate, the first being the T &TEC Power Plant. Eventually, a natural gas distribution network will make natural gas available to other areas of Tobago for uses including CNG as a vehicular fuel.

Other Interesting Facts

• It is the first natural gas pipeline to Tobago.
• Construction of the pipeline facility began in May 2009.
• Construction of the Offshore Pipeline began in November 2009.
• The pipeline was commissioned and pressured up to 45psi with nitrogen on 17th August, 2011
• NGC used the Horizontal Directional Drill (HDD) technology in the pipeline’s shore approach to minimize impact on the coral reefs.
