Tankers of Russian oil sailing through the Danish straits will be more likely to crash and spill their cargoes if they transit the shallow treacherous waters without the specialist pilots usually provided to vessels in the channel, Denmark’s maritime authority has warned.
The narrow stretch of water between Denmark and Sweden at the mouth of the Baltic Sea is a key trade route for Russian oil heading by sea to markets around the world.
Under a 165-year-old treaty signed in Copenhagen in 1857 all international vessels have the right to transit the straits but Denmark must make pilots available to help vessels navigate its many islands and sandbanks.
