SINGAPORE, Dec 7 (Reuters) - Asian gasoil prices remained weak as adequate

supply weighed on the market amid weak demand and due to a limited impact on

prices after an earthquake in Japan.

The January gasoil crack slipped 19 cents to $20.37 a barrel above Dubai

crude, Reuters data showed.

A strong quake centred off northeastern Japan shook buildings as far away as

Tokyo on Friday and triggered a one-metre tsunami in an area devastated by last

year's Fukushima disaster, but there were no immediate reports of deaths or

serious damage.

But no irregularities were reported at any of the nuclear plants or oil

refineries after the area was hit by the 7.3 magnitude earthquake, companies and

a nuclear regulator said.

Traders appeared to have also already priced in an impending planned

maintenance in Malaysia.

Malaysia's national oil firm Petronas is likely to shut a

100,000-barrels-per-day (bpd) crude distillation unit at the Melaka-2 facility,

on Malaysia's west coast, for about 2-1/2 weeks in January, an industry source

said.

'But there should be minimal impact in terms of imports during the time,' the

source added.

This coincides with planned maintenance by Reliance Industries at its newer

refinery in Jamnagar. But the impact on prices is limited as demand is still

weak within Asia, traders said.

Also adding to supply, India's Mangalore Refinery and Petrochemicals Ltd

(MRPL) and Taiwan's CPC Corp have issued tenders to sell gasoil in January.

Swiss trader Trafigura has provisionally booked the Bright Grace to load

230,000 tonnes of gasoil from South Korea on Dec. 19, industry sources said. The

cargo is likely headed to West Africa, one of them said.

It is not clear if the vessel is being chartered for floating storage, but

Trafigura has bought at least about 1 million barrels (or about 135,000 tonnes)

of high sulphur gasoil to be loaded from Singapore in December, Reuters data

showed.

The company is a regular supplier of the fuel into Africa and often charters

floating vessels to store gasoil in that region, an industry source said.

* TENDERS: MRPL has offered 40,000 tonnes of jet fuel for Jan. 18-20 loading

and 40,000 tonnes of 0.5 percent sulphur gasoil for Jan. 9-11 loading. Both

tenders close on Dec. 12 and are valid until Dec. 13.

- CPC has offered 250,000 to 300,000 barrels of 500 ppm sulphur diesel and

60,000 barrels of one percent sulphur gasoil for loading in January. The tender

closes on Dec. 10 and is valid until Dec. 12.

* SINGAPORE CASH DEALS: One jet deal, two gasoil trades.

- Hin Leong sold 245,000 barrels of jet fuel for Dec. 23-27 loading to China

Aviation Oil at a premium of 10 cents a barrel to the average of Dec. 24-31

Singapore quotes.

- Shell bought 150,000 barrels of 500 ppm sulphur gasoil for Dec. 22-26

loading from Trafigura at a premium of 30 cents a barrel to the average of

January quotes.

- Hin Leong sold 250,000 barrels of 0.5 percent sulphur gasoil for Jan. 2-6

loading at a discount of $1.10 a barrel to the average of January quotes.
