Russia detains Estonia-bound cargo ship Västerbotten in the Gulf of Finland

The Navalis-operated general cargo ship was stopped on the agreed route to Sillamäe and released the next day

Russian border guards detained the Cyprus-flagged general cargo ship Västerbotten in the Gulf of Finland on 1 October as she sailed from Mönsterås in Sweden to the Estonian port of Sillamäe. Estonia's Police and Border Guard Board confirmed the detention.

The ship was stopped after entering Russian territorial waters on a route available under an arrangement between Russia, Estonia and Finland, which lets larger vessels avoid the shallows on the Estonian side of the gulf. She was anchored in Russian waters while she was inspected, and Russia temporarily restricted passage through the area before lifting the restriction. Västerbotten then resumed her voyage and reached Sillamäe by the morning of 2 October.

The Estonian Transport Administration said it had received no explanation from the Russian side. "Every country has the right to exercise control over ships in its territorial sea, and apparently the Russian administration considered it necessary to inspect this ship when it passed through their territorial sea," said Are Piel, head of the administration's vessel traffic management department.

Västerbotten, IMO 9436226, is a 6,800 dwt general cargo ship built in 2008 and measuring 119.3 metres. She is listed in the Baltic fleet of the German operator and broker Navalis Shipping.

It is not the first such case on the Sillamäe approach. In May 2025 Russia detained the Liberian-flagged tanker Green Admire after she left the port using the same agreed route through Russian territorial waters. Estonia's Transport Administration then said that ships travelling to and from Sillamäe would be directed through Estonian territorial waters instead.
