A shipowner has written to the UK government urging action following a court ruling that appears to bar non-German crews from vessels working on construction projects in Germany's territorial waters.

Germany's Federal Administrative Court has decided that seafarers from third countries require a residence permit for employment on offshore support vessels.

The ruling is the culmination of a long legal fight following the removal by German police of two overseas seafarers from the 81-loa multipurpose support vessel Atlantic Tonjer (built 1983) in 2017.
