FRANKFURT, July 25 (Reuters) – Siemens Energy (ENR1n.DE) said on Monday that a turbine that Moscow says limits the capacity of the Nord Stream 1 gas pipeline was ready for delivery, but Russia’s Gazprom (GAZP.MM ) had to provide customs documentation for the transfer to take place.

“The transport of the turbine could start immediately. The German authorities provided Siemens Energy with all the necessary documents for the export of the turbine to Russia at the beginning of last week,” the company said.

“Gazprom is aware of this. What is missing, however, are the customs documents for importing into Russia. Gazprom, as a customer, is obliged to provide them,” the company added.

Gazprom did not immediately respond to a request for comment.

Siemens Energy serviced the turbine in Canada and is responsible for bringing it back to Russia, a process that has proven difficult as Moscow requires specific documents that show the transfer does not violate sanctions.

The German company‘s comments come shortly after Gazprom, which owns the majority of Nord Stream 1, announced it would be shutting down another turbine and that would reduce the pipeline’s capacity to 20% from July 27, against 40% now.

“Maintenance of our turbines is and remains a routine procedure. Over the past 10 years of maintenance, there have been no significant complications,” Siemens Energy said.

“Any future maintenance work can be facilitated: the Canadian government has already agreed that the wind turbines, which are maintained by Siemens Energy in Montreal, can be transported from Canada to Germany. At this time, therefore, we see no connection between the wind turbine and the gas cuts that have been put in place or announced.”
