Angola's new liquefied natural gas (LNG) export project aims to charter out its entire tanker fleet for at least a couple of months after a major rupture on a flare line crippled output at the $10 billion plant last month. The project partners led by U.S. oil major Chevron have approached shipbrokers to charter out all seven LNG carriers dedicated to Angola's liquefaction facility, three sources said. One of the tankers has already been chartered to a shipper and is due to load a cargo in Nigeria soon. "The other ships are currently being discussed ... some of the charters being discussed are at least until July or August," one of the sources said. Another source said Angola LNG had expressed interest in locking in any charters that become available. "But they have been very vague about how long they can charter out the ships," that source said. Last month's rupture of a flare line at Angola LNG was the latest in a string of production setbacks since the plant started production in June 2013.
