The imposition of further sanctions from Western nations against Russia, affecting its oil and gas industry, will cause the dark fleet to remain in operation for the purposes of circumnavigating those sanctions. Most of this dark fleet have substandard maintenance with no insurance, posing a major risk for the environment in case of an oil spillage and a lack of recourse to other vessels following collision incidents. The main risks will come from the highly dangerous and environmentally perilous ship-to-ship transfers on the high seas with no proper oversight. With no realistic end in sight for the Russia-Ukraine conflict, the risks posed by the dark fleet regrettably appear here to stay in the short-medium term and the insurance industry will need to consider the level of capacity it can and will allocate to this area.
