Under the terms of the agreement, BP will supply the LNG from its equity stakes in Freeport LNG in Houston, US and global portfolio.
The Freeport LNG project’s final investment decision is expected to be made by the end of 2014.
Pavilion Energy and Pavilion Gas chief executive officer Seah Moon Ming said: "We are delighted to collaborate closely with BP. The conclusion of a long-term agreement with BP, which involves LNG supply from the US, is another significant development for Pavilion Gas.
"This deal is part of our continued effort to enhance and diversify our LNG portfolio to deliver sustainable and competitive LNG supply to Asia."
Earlier in 2014, Pavilion signed a 10-year agreement to buy 0.7 million tons of LNG a year from Total starting in 2018.
In addition to managing downstream natural gas operations for both PNG and LNG in Singapore, Pavilion Gas is also responsible for the marketing, trading and distributing of natural gas in Singapore.
