LONDON, Jan 17 (Reuters) - Gasoline barge prices in northwest Europe climbed further on Monday to fresh 28-month highs on unseasonal refinery maintenance in France.
Traders said maintenance at France Exxon's Fos-sur-Mer refinery, expected to continue for five weeks after starting on Friday, had contributed to the upturn. The plant normally produces 115,000 barrels a day [REF/E].
The Fos-sur-Mer outage was "definitely" helping, one trader said, while maintenance to come in the Mediterranean in February had also supported prices, he added.
Barge trade into Germany, France and Switzerland along the river Rhine remained closed for a fifth day by a capsized tanker loaded with sulphuric acid and German navigation authorities said the route could be blocked until the weekend [ID:nLDE70G1EY].
