“Russia’s rejection of a proposed Black Sea moratorium removes a potential mechanism for reducing attacks against civilian shipping and maritime infrastructure. Ambrey assesses it is a realistic possibility that Ukraine will maintain or increase pressure against Russian maritime and port infrastructure to raise the cost of Russia’s refusal and strengthen its negotiating position. Further attacks against merchant shipping and maritime infrastructure remain highly likely, with the wider Novorossiysk port complex particularly exposed”
EXECUTIVE SUMMARY
- On 14 August 2026, the Russian Ministry of Foreign Affairs rejected proposals for a moratorium on military activity in the Black Sea. Spokesperson Maria Zakharova stated that Moscow saw “no grounds for half-measures that merely grant the Kyiv regime temporary breathing space”.
- The proposal had been advanced by Turkish Foreign Minister Hakan Fidan on 8 August 2026. Ukraine separately transmitted an offer, via a third party, to halt attacks against civilian vessels in the Black Sea.
- Ambrey assesses Russia’s rejection as a detrimental development for the maritime security environment. It removes a potential mechanism for reducing attacks against civilian shipping and maritime infrastructure.
- It is assessed as a realistic possibility that Ukraine will maintain or increase pressure against Russian maritime and port infrastructure in order to raise the cost of Moscow’s refusal.
- On the 17th of August, Ukraine sanctioned, Greek owned crude oil tanker was struck while loading at the CPC terminal.
- On 12 August 2026, Ukrainian UAVs, missile and unmanned surface vessel (USV) strikes against Novorossiysk killed three people, wounded at least 24, and put two grain terminals out of action. Ukrainian officials reported strikes against naval vessels, piers and seaport infrastructure.
- The Sheskharis crude export terminal at Novorossiysk has been struck repeatedly during 2026, including on 2 March and 6 April, when six of seven loading arms were reported damaged on each occasion, temporarily halting loadings.
- Ambrey assessed that the Caspian Pipeline Consortium (CPC) Terminal remains comparatively less exposed following a reported understanding between Kyiv and Washington in early August 2026, under which Ukraine agreed to refrain from striking non-Russian, non-sanctioned tankers and CPC infrastructure. This should not be interpreted as a security guarantee.

Spokesperson Maria Zakharova stated that Russia saw “no signs of improvement in the situation” and therefore “no grounds for half-measures”, while asserting that no formal proposal had been received…
