Qatargas Operating Company Limited was formed in July 2005 for the purpose of constructions of Qatargas 2, Qatargas 3, Qatargas 4, Laffan Refinery and other assets on behalf of the shareholders.[1] Qatargas also announced a moratorium on further development of the North Field in 2005, and ordered further studies and a review of the field, which were expected to end in 2010. The moratorium was initially expected to remain in place until 2013 or 2014 but was lifted in 2017.[13][14] In 2006 the construction for QG3 and QG4 started and RasGas' Train 5 was erected. The train was inaugurated in 2007 as well as the first 0-Max LNG carrier "Al Dafna" floated out of its dry dock (delivered in 2009) and the first 0-Flex ship delivered to Qatargas.[15]
