Total said on Friday it had suspended operations at some units of the 230,000 barrel-per-day Leuna refinery in Germany for technical checks following the prolonged situation of contaminated Russian crude supply.

Industry monitor Genscape said earlier on Friday that the 112,000 bpd vacuum distillation unit at the refinery was one of the units that was halted.

"German refiners will need to import roughly 400,000 barrels per day in the second half of the month in order to return to normal rates," FGE said in a note on the fallout of the Druzhba pipeline outage.

BP has brought forward a planned turnaround on the 200,000 barrel per day crude unit (CDU3) at its Rotterdam, Netherlands, oil refinery to May, traders said.

Fuel oil stocks in independent storage in the Amsterdam-Rotterdam-Antwerp (ARA) refining and storage hub rose by 34.4 percent in the week to Thursday, data from Dutch consultancy Insights Global, previously PJK International, showed.

Gasoil stocks were slightly higher on rising imports from the United States and as demand up the Rhine river decreased slightly, Insights Global's Lars van Wageningen said.

US distillate stockpiles, which include diesel and heating oil, rose last week by 84,000 barrels, versus expectations for a 1 million-barrel drop, EIA data showed.
