NGC’s Major Transmission Pipelines
Tobago Pipeline Project
The Tobago pipeline is a 12-inch line which can carry up to 119 mmscf/d from the BHP Billiton offshore field to the Cove Eco-Industrial Business Parkland in Lowlands, Tobago. The first gas was received in November 2012 and the pipeline now supplies natural gas to the T&TEC power generation plant located at Cove. It will also supply natural gas to the prospective light industrial users at the estate. In addition, the pipeline also creates the potential to supply other areas of Tobago, and can facilitate the transportation of natural gas to the Eastern Caribbean.
36-inch North-Eastern Offshore Pipeline (NEO)
The North-Eastern Offshore Pipeline (NEO) was commissioned in 2011. It runs from the BHP Billiton Gas Export Platform (GEP) in the Angostura field, located off the north-east coast of Trinidad, to Mayaro Bay. The line continues on land to NGC’s new accumulator station at its Beachfield facility.
- First gas delivered in May 2011
- 94 km, 36-inch-diameter pipeline runs southwards from the BHP Billiton Gas Export Platform located in the Angostura Offshore field to Mayaro Bay. The line continues on land to NGC’s Beachfield facility.
- NEO delivers 220 MMscf/d
Union Pipeline supplies natural gas to present and future customers located on the Union and La Brea Industrial Estates. The Project facilitates the flow of 220 MMscf/d of natural gas and was commissioned in April 2011.
Beachfield Upstream Development (BUD) Pipeline
The 36-inch-diameter BUD marine line was constructed in 2004. It served as the catalyst for NGC to deepen and expand its operations at Beachfield. The capacity of NGC’s pipeline system increased from 1.4 Bcf to 2 Bcf in anticipation of higher demands by new gas-based customers.
In 2005, NGC established a new department, Beachfield Operations within the Pipeline Operations Division to manage and maintain its expanded and upgraded facilities in the Beachfield area (including the older facilities at Abyssinia, Mayaro and Galeota). This department will also provide emergency response assistance to emergency situations occurring on the lines and facilities within the immediate areas of Mayaro, Galeota, Guayaguayare and Beachfield.
56-inch Cross-Island Pipeline
The 56–inch diameter Cross-Island pipeline was commissioned in 2005. It transports natural gas on behalf of LNG shippers, including bpTT, BGTT and NGC for the Atlantic LNG Train IV in Point Fortin and also supplies industrial estates at Union and La Brea in southwest Trinidad.
The pipeline is 76.5 kilometres long with a design capacity of 2.4 BCF and an inlet pressure of 950 psi; with compression, its capacity can increase to 3 BCF. At the time of its completion, it was the largest diameter natural gas pipeline in the western hemisphere and its first use on November 25th 2005 heralded the successful commissioning of the US$260 million pipeline project on schedule and within budget.
36-inch Pipeline from Beachfield to Point Lisas – “Project 2000”
This 36 -inch line from Beachfield to Point Lisas via Picton, known as “Project 2000”, was commissioned in 1999. It is 97.3km long and supplies gas to customers in Point Lisas.
36-inch-diameter pipeline from Beachfield to Point Fortin
This 36-inch-diameter line runs from Beachfield to the Atlantic LNG facility at Point Fortin via Picton.
30-inch Pipeline from Beachfield to Point Lisas
30-inch-diameter pipeline was commissioned in 1982, running from Beachfield to Point Lisas via Rio Claro and Tabaquite.
24/20-inch Offshore/Onshore Pipeline
The 24/20-inch offshore/onshore pipeline was built in 1978 to transport gas from the Teak and Poui fields to Point Lisas. Today, it also collects gas from the Osprey field.
16-inch Penal to Port of Spain Pipeline
This line was built over 50 years ago by T&TEC to transport natural gas from the Penal gas fields to the Port of Spain power plant. It is the oldest existing natural gas transmission line in the country and is still in use today.
NGC’s Distribution Network
NGC has an extensive distribution network which ranges from 2-inch to 14-inch diameter pipelines. The network delivers gas to petrochemical and heavy industrial plants at Point Lisas; the light industrial/manufacturing sector; the commercial sector and various gas stations which are equipped for the sale of CNG.
This network is constantly being upgraded and extended. At present, a 6-inch diameter carbon steel pipeline system to e-Teck Park at Diamond Vale is being built.
