ISTANBUL — The Turkish research vessel at the heart of an energy dispute between Turkey and Greece is back at port.
In a tweet Monday, Turkey’s energy ministry said the Oruc Reis had returned to port in Antalya after completing two-dimensional seismic research in the Demre field. Ship tracker MarineTraffic showed the survey ship had docked.
Tensions between the two neighbors and nominal NATO allies escalated over the summer with a military build-up after Turkey sent the survey ship, escorted by navy frigates, into disputed waters in the eastern Mediterranean.
The move prompted Greece to also send its warships, and both countries conducted military exercises to assert their claims. NATO intervened, organizing technical talks between the two countries’ militaries to prevent a potential armed conflict.
Ankara says the Greek and Greek Cypriot governments are impinging on the energy rights of Turkey and breakaway northern Cyprus by setting maritime boundaries according to their own interests and attempting to exclude Turkey from potential oil and gas reserves.
Turkey says maritime boundaries for hydrocarbon resources should be calculated from the mainland but Greece says the continental shelves of its islands dotting the Mediterranean should be included within its energy zone.
The competing claims have led to a diplomatic crisis and aggressive rhetoric. European Union members Greece and Cyprus, along with France, have called for sanctions on Turkey
The Oruc Reis was pulled back to port in September for maintenance and resupply. Turkish officials said it was withdrawn from Greek-claimed waters to give diplomacy a chance. It was redeployed in October after Turkish President Recep Tayyip Erdogan accused Athens of failing to fulfill promises.
EU leaders are meeting for a summit on Dec. 10-11 and are expected to discuss the dispute and possible sanctions.
