Greek-run oil tanker struck in Black Sea while awaiting Kazakh crude cargo

A Greek-flagged suezmax tanker was struck by a suspected drone or missile in the Black Sea on March 14, positioning approximately 14 nautical miles off Novorossiysk, Russia. The vessel, the Maran Homer, sustained minor deck damage but remained seaworthy, and all 24 crew members, including 10 Greek nationals, escaped injury.

The attack occurred at roughly 04:35 local time while the tanker was sitting in ballast, waiting to load Kazakh crude at the Caspian Pipeline Consortium terminal. The Maran Homer hadn’t even taken on cargo yet when it was hit.

A pattern that keeps repeating

No group has claimed responsibility for the strike, though the incident fits a now-familiar pattern of suspected Ukrainian sea drone attacks against commercial vessels operating near Russian Black Sea ports. Similar strikes targeted other Greek-operated tankers in July 2026, and those incidents also resulted in no environmental pollution or crew casualties.

Following the pattern of strikes, Greece’s shipping ministry issued heightened security advisories urging tankers to bolster protective measures when transiting the region.

The Maran Homer is operated by Maran Tankers Management and had been chartered by Chevron, connecting one of the world’s largest oil majors to the incident.

Why the CPC terminal matters

The Caspian Pipeline Consortium terminal at Novorossiysk carries crude from Kazakhstan’s Tengiz and Kashagan fields to the Black Sea coast, where tankers pick it up for delivery to global markets. Kazakhstan exported roughly 1.3 million barrels per day through the CPC system in recent years, making it one of the world’s most significant single-terminal export points.

Insurance, freight, and the cost of risk

War-risk insurance premiums for vessels entering Black Sea waters have climbed significantly since Russia’s full-scale invasion of Ukraine in 2022, and each new incident gives underwriters fresh justification to keep rates elevated or push them higher. Higher insurance costs flow directly into freight rates, which means the cost of moving crude from the CPC terminal rises and the delivered price of Kazakh oil to refineries in Europe and the Mediterranean increases accordingly.
