Qatargas agreed to deliver the LNG to Canaport using both Q-Flex and Q-Max vessels, each holding the equivalent of approximately 5.6 and 4.6 billion cubic feet of natural gas, respectively.[34][35] Further major deliveries were made to Dubai and France and in 2010 further talks with the United Kingdom were initiated and a Heads on Agreement was signed. In June 2011 Qatargas then signed a three-year LNG deal with Centrica (UK), valued at around $3.24 billion at the time. The contract has since then been extended to a four-and-a-half-year contract in June 2014 and the latest contract extending the partnership until December 2023.
