Turkish-owned Azov Concorde sunk by drones off Bulgaria

Two merchant ships were hit by drones in Bulgaria's exclusive economic zone overnight on 13 October. The Turkish-owned Azov Concorde sank 17 nautical miles off Krapets; five seafarers were rescued and 11 are missing.

Location: OFF KRAPETS

According to the Sofia Globe, the St Vincent and the Grenadines-flagged Azov Concorde sank, while all 15 crew of the Malta-flagged Chelsea 3 were rescued. Chelsea 3 had sailed from Türkiye; its crew said they saw three drones. UNN reports that the governor of Dobrich said 11 seafarers were missing; an interior ministry official could not firmly confirm the sinking. This is the second wave of attacks in Bulgaria's economic zone since 6 October.

Bulgarian Prime Minister Radev said he had no conclusive proof, but that it made no sense for Ukraine to strike its own ships, and he met Russian Ambassador Mitrofanova. The Sofia Globe says Bulgaria's defence minister discussed Black Sea security the same day with his Turkish counterpart Yaşar Güler and the Romanian minister. Euronews cites İMEAK data showing 226 ships affected since February 2022, 163 of them in the first eight months of 2026.

Talay assessment

Bottom line

The attack came after two days in which Kyiv had paused refinery strikes; ship attacks in the Black Sea are not decoupled from the energy bargain. The Turkish-owned fleet has lost three ships in nine days, and Ankara's moratorium text remains unsigned. The likeliest path is that attacks in the economic zones continue and the cost falls on Turkish shipowners.

Likely effects

  • Freight and insuranceNegativeWeeks

    Every voyage outside territorial waters carries a war-risk premium; a premium of $2.5 million per voyage pushes the ageing Turkish-owned dry-bulk fleet out of the basin.

  • TürkiyeNegative1–6 months

    Exempt 12-mile territorial-water routes funnel traffic towards the Turkish coast and the approaches to the Bosphorus.

  • NATO flankUncertain1–6 months

    Bulgaria is taking satellite-monitoring and naval-mission proposals to the 15–16 October EU summit; the Montreux debate could reopen.

Possibilities, ranked

    Attacks continue55%

    Sporadic but regular attacks continue in the economic zones, and the moratorium goes unsigned.

    If the refinery–grid ceasefire is firmed up, a pause in ship attacks enters the package.

    The EU sets up a monitoring mission on Bulgaria's proposal, and Türkiye's role comes up for debate.
