CPC Oil Loadings Falter Amid Safety Issues and Tanker Shortages

Main Developments in CPC Oil Loadings

Operational Suspensions and Safety Concerns

LONDON/MOSCOW, Aug 5 (Reuters) - The Caspian Pipeline Consortium has repeatedly suspended operations this week because of safety concerns and a lack of tankers, numerous trading sources said, as the main export route for Kazakh crude oil struggles to recover from drone attacks.

Loadings from the pipeline, which carries about 1.8% of global oil supply from Kazakhstan to Russia's Black Sea coast, have been disrupted since the middle of last month, adding to the supply outages linked to the U.S.-Israeli war on Iran.

So far this week, the pipeline has been only briefly reopened and was closed on Wednesday, the sources said.

Impact on Shipping and Tanker Availability

Shipowners have become reluctant to take on CPC voyages because of the threat of drone attacks.

Russian group FESCO on Tuesday suspended operations in the region, while one CPC Blend seller told Reuters it took several attempts to find a tanker to load a cargo in recent weeks.

Geopolitical Tensions and Accusations

Russia's Foreign Ministry on Monday accused Ukraine of attacking oil tankers during loading at the Caspian Pipeline Consortium terminal at Novorossiysk, and said that Kyiv was trying to destabilise global oil markets.

Kyiv has not claimed responsibility or made any comment on why it may have extended its campaign against Russia to a pipeline that carries crude produced largely by U.S. and European oil majors.

None of the eight sources Reuters spoke to could be named because they were not authorised to speak publicly.

Response from Kazakhstan and Market Impact

Kazakhstan's Energy Ministry said on Saturday that a complete halt to CPC operations was not under consideration and that the situation was under control. The ministry had yet to respond to a request for comment on Wednesday.

CPC declined to comment. 

Production Cuts and Alternative Export Routes

Landlocked Kazakhstan relies heavily on Russian ports to export crude by sea, meaning that pipeline and loading disruptions can force production cuts. In July, when attacks on tankers intensified, Kazakhstan's oil output fell by 14% from June.

Tengizchevroil plans to export about 100,000 metric tons of oil by rail to Georgia's Black Sea port of Batumi in August, sources said.

Price Effects and Market Differentials

CPC Blend differentials have weakened due to the disruptions. 

August-loading CPC Blend cargoes were offered at nearly $4 a barrel below dated Brent this week, compared with a premium to dated Brent just a few weeks ago, traders said.

Key Takeaways

  • CPC loadings have been intermittently halted this week due to tanker scarcity and elevated safety risks, driven by drone strikes, notably around the Black Sea terminal at Novorossiysk. (euronews.com)
  • These disruptions have deepened production woes—Kazakhstan’s oil output reportedly fell 14% in July—and depressed CPC Blend differentials to nearly $4 below dated Brent. (euronews.com)
  • Kazakh authorities and energy firms are exploring alternate routes such as rail shipments via Georgia and diversifying away from CPC’s vulnerable infrastructure to mitigate future disruptions. (s3-prod.exia.kz)
