MOSCOW, July 16 (Reuters) - Russian gas exporter Gazprom said on Saturday it expected Siemens to meet its obligations in full when servicing gas turbines needed for the reliable operation of Nord Stream 1 gas pipeline and energy shipments to Europe.

Gazprom said it had asked Siemens to show documentation that would allow a turbine to be brought to a Nord Stream 1 compressor station, despite Western sanctions.

Kremlin-controlled Gazprom said earlier this week it could not guarantee the safe operation of a critical part of the Nord Stream 1 gas pipeline because of doubts over the return of the turbine. (Reporting by Reuters Editing by Mark Potter)
