Russia's Gazprom said it would ship 42.7 million cubic meters (mcm) of natural gas to Europe through Ukraine on Saturday, hours after it announced that flows through the Nord Stream 1 pipeline to Germany would not resume due to malfunctions at a compressor unit.

Flows via the Sudzha entry point were up slightly compared to the 41.3 mcm Gazprom sent on Friday, but not enough to compensate for missing gas that was expected to be pumped through Nord Stream 1 on Saturday.

In a statement on Saturday, Gazprom said Siemens Energy, which normally services Nord Stream 1 turbines, was taking part in repair work in accordance with an existing contract between the two companies and was ready to fix faults which Gazprom said had forced it to halt gas supply to Germany through the pipeline.

"Siemens is taking part in repair work in accordance with the current contract, is detecting malfunctions ... and is ready to fix the oil leaks. Only there is nowhere to do the repair," Gazprom said in a statement on its Telegram channel.

On Friday evening Gazprom said it had detected an oil leak in a turbine and would not resume gas supply to Germany via Nord Stream 1 until it had been fixed, adding that the repairs can only be carried out at a specially fitted workshop. Earlier that day, the Group of Seven countries agreed to impose a price cap on Russian oil.
