News: ORG UPDATE 1-Angola LNG returns to global market with first post-shutdown cargo

• Angola LNG's return brings relief amid project delays
• Up to six more cargoes may be offered by Angola-trader

(Adds background and trader comments on market impact)

Angola's recently refurbished liquefied natural gas (LNG) export project launched a tender to sell its first cargo since the plant was unexpectedly shut down in April 2014, trade sources said.

According to tender document details relayed by traders, the cargo was loaded between June 3 and 5 on board the Sonangol Sambizanga tanker and bid submissions are due on the morning of June 13, trade sources said.

The tender is valid until June 15, one source said, while a second trader said that up to six more cargoes could be loaded before the facility goes offline for a final phase of testing.

In the current tender the delivery date of the first cargo varies according to the location of terminals dotted around the globe.

For example, the Chevron-led project CVX.N lists a six-week delivery window for Argentina's Bahia Blanca terminal - between June 28 and August 14, a trader said.

The cargo may be priced based on levels at Britain's gas trading hub, the National Balancing Point, or as a percentage of Brent crude oil, he added.

MARKET IMPACT Resuming supply from Angola may bring a measure of relief to buyers as delays to new projects and supply outages have helped nudge spot LNG prices higher in recent weeks.

The combined impact of delays means there is less supply in the market than traders previously assumed, prompting some to cover short positions they otherwise intended to keep open.

Exports from Chevron's new Gorgon export facility in Australia are not expected to resume until the end of the month, say industry sources, following an unplanned shutdown in April.

Meanwhile, Houston-based Cheniere Energy LNG.A has already said that the completion of its second production line at Sabine Pass would be delayed until August, from June.

And a second line at Origin Energy's (ORG) AP LNG project is also running behind schedule, sliding from the third-quarter into the fourth, according to sources.

Angolan supply, although still slight by global measures, may help allay any residual fears of supply tightness as Asian markets head into peak summer demand season, traders have said.

Chevron CVX.N has a 36.4 percent share in Angola LNG, while Angolan state oil firm Sonangol has 22.8 percent. Other stakeholders include Total TOTF.PA , BP BP.L and ENI ENI.MI .
