UPDATE 1-Sri Lanka to shut refinery after exhausting crude supply

* Refinery to get its next crude shipment on Nov 8-9 from

Dubai

* Ceypetco struggles to buy Iranian oil due to western

sanctions

* Refinery configured to run on Iranian crude

(Adds details)

SINGAPORE/COLOMBO, Oct 25 (Reuters) - Ceylon Petroleum Corp

(Ceypetco) will shut Sri Lanka's sole 50,000 barrels-per-day oil

(bpd) refinery for two weeks on Friday after exhausting its

supply of mainly Iranian crude oil, a company official said.

The company has enough crude to last until Friday and will

receive its next crude oil shipment from Dubai on Nov. 8 or Nov.

9 when the refinery will restart, Ceypetco general manager

Susantha Silva told Reuters.

The refinery will also undergo maintenance during the

shutdown, he added.

The refinery is configured to run on Iranian crude and has

been scrambling to fill a shortfall after it was unable to bring

in Iranian crude because of Western sanctions.

"This does not mean we are going to close down the refinery

permanently. This will be a temporary closure," said Silva.

"We are getting one crude parcel from Dubai on Nov. 8 or 9

and one from Saudi Arabia on Nov. 13. Another one scheduled

(from Abu Dhabi) in December. So we have lined up crude for

refining."

Exports from Iran, which is grappling with tough Western

sanctions targeting its energy and petrochemical sectors, have

fallen sharply as consumers struggle both to pay for the oil and

to secure insurance cover for tankers to ship the crude.

Ceypetco has been having problems running the refinery at

full capacity as alternative crudes like Arabian light are not

able to give the refinery the proper yield, Silva said earlier.

Sri Lanka, which is dependent on Iranian crude oil, has

reduced its Iranian crude imports by 20 percent this year, but

disagrees with Western sanctions that are punishing countries

that depend on its oil, Foreign Minister G.L. Peiris said

earlier this week.

The country is now in talks with Iran to find suitable

payment method for its crude, as banks dealing with Iran have

also been targeted by western sanctions. Iran has not offered

any discounts on its crude, Peiris said.

U.S. Secretary of State Hillary Clinton said in June the U.S.

would exempt Sri Lanka, among other nations, from financial

sanctions because they have significantly cut purchases of

Iranian oil.

Ceypetco's Sapugaskanda refinery, on the outskirts of the

capital, Colombo, was last shut early in September after damage

to a floating pipeline at the Colombo port.

The sanctions have so far defeated three attempts by Sri

Lanka to obtain Iranian crude as the company struggles with

getting shipping insurance and payment on the Iranian oil, Silva

has said.
