Project Profile

Value: US$10,000 billion
Location: Block 17 and Block 2, to Soyo (plant), Zaire Province, Angola
Area: unknown
Capacity: 5.2 million tonne/year  
Start-up Year: 2012


The plant, located in Angola on the Congo River delta, will have the capacity to produce 5.2 million metric tons per year of LNG—natural gas cooled to minus 160 degrees Celsius. At that temperature, natural gas becomes a liquid that occupies one six-hundredth the volume of gas, so it can be transported safely and economically by sea. The LNG from Angola will be exported primarily to a regasification terminal in Mississipi.

The plant will feature technology developed by ConocoPhillips. The US$8 billion gas program includes floating production storage and operations vessels, pipelines to the LNG plant, and LNG tankers. In addition to LNG, the project will produce liquefied petroleum gas such as propane and butane; condensate; and domestic pipeline gas. Angola, the second-largest oil producer in sub-Saharan Africa after Nigeria, is one of the world’s fastest-growing economies due to an ongoing boom that led to the nation’s decision to join OPEC in 2007. With expansion of the liquefied natural gas industry, a second energy-driven boom has begun.

Contractors:

Flow-Cal: Delivered software enabling tracking and management of Angola LNG’s gas delivery on its pipeline network of over 500km from offshore oil fields to the processing and liquefaction plant in Soyo. Flow-Cal’s software has also been selected for the construction phase of the Soyo LNG plant. With the plant now in full operation Flow-Cal has completed the site acceptance testing, onsite consulting services and application training for the measurement team. (Dec, 2016)

Boskalis: Contract for dredging activities related to maintaining the access channel and turning basins of the Soyo LNG port. The project will be executed in joint venture and involves the removal of approximately 11 million cubic metres of sand and silt by medium-sized trailing suction hopper dredgers. Work is set to commence in the third quarter of 2015 and will be completed by the end of 2017. Boskalis also executed the initial capital dredging and reclamation works for this LNG port on behalf of Angola LNG Ltd. from early 2007 until mid-2009.
