* Trans Alaska Pipeline boosting flows towards 500,000 b/d
* Technicals show U.S. crude heading below $90
* Coming Up: IEA oil market report for January (Updates prices)

SINGAPORE, Jan 18 (Reuters) - Brent crude futures edged higher on Tuesday after OPEC members signalled the group would maintain production levels even as prices flirt with $100 a barrel, while the resumption of shipments through the Trans-Alaska Pipeline capped price gains.
ICE Brent for March added 32 cents to $97.75 a barrel at 0736 GMT. The front-month Brent contract on Friday touched $99.20, the highest price since October 2008.
With the installation of a bypass completed, operators of the Alaskan line expect to ramp up flows to 500,000 barrels per day (bpd) by Tuesday, more than a week after a leak forced the duct's closure. Shipments are set to reach to 640,000 bpd, or about 12 percent of U.S. output, within days.
"There is no fresh catalyst to boost oil prices further," said Serene Lim, a Singapore-based oil analyst at ANZ. "It seems that $100 is a very huge psychological barrier."
Producers including BP , ConocoPhillips and Exxon Mobil got permission to resume normal output from Alaska's North Slope on Monday afternoon after the pipeline reopened, and will gradually boost volumes over the coming days, a spokeswoman from operator Alyeska said.
The head of the International Energy Agency (IEA), an adviser to 28 industrialised countries, on Monday described the current oil price as "alarming" and warned it could be damaging to the world economy.
Still, the United Arab Emirates' oil minister said he was not concerned by rising prices, echoing comments by Organization of the Petroleum Exporting Countries producers Iran and Venezuela this week. Algeria's oil minister also said the oil market was balanced.
"In their minds, they say that the world oil market remains well supplied, so they might keep production targets intact for the time being until prices spike," Lim from ANZ said.
U.S. crude benchmark prices fell 31 cents to $91.23, but most of that drop came during Monday. The New York Mercantile Exchange (NYMEX) is combining Monday's and Tuesday's trades into one session because of the Martin Luther King holiday and will produce just one settlement after Tuesday's close.
"We view the recent oil price strength as temporary and mainly driven by below normal temperatures in the Northern Hemisphere," said Credit Suisse analysts including Stefan Graber. "As temperatures normalize, we think oil prices may fall in the weeks ahead."
The spread between the ICE and NYMEX front-month futures contracts has narrowed since February Brent expired on Friday. At one point on Friday, the spread between the two February contracts exceeded $8 a barrel, its widest in 23 months.
Weekly U.S. inventory reports from the American Petroleum Institute and the Energy Information Administration are usually delayed by one day to Wednesday and Thursday respectively whenever a holiday falls on a Monday.
In its monthly report on market conditions, OPEC maintained the view that consumers have enough oil, blaming the run-up in prices on the early onset of winter weather and an increase in investment flows into commodities.
OPEC raised its global oil demand growth forecast by 50,000 barrels per day (bpd) to 1.23 million bpd in 2011, and said the world oil market remained well supplied and inventories should build in the first half of the year.
In other markets, the euro was on shaky ground on Tuesday with no imminent decision in sight on how to beef up the euro zone's rescue fund, while Asian tech shares outperformed despite news that Apple Inc CEO Steve Jobs is taking medical leave.
