Switzerland-based Atlanship, owner of six specialised, refrigerated orange-juice tankers, has given notice that it is appealing a US federal court decision ordering it to pay some $13.3m over a collision that wrecked a US-flag dredger and put it out of service for 218 days.

Earlier this month, the Southern District of New York (SDNY) federal court awarded the owner of the 1,485-gt backhoe dredger New York (built 1999) and its bareboat charterer, Great Lakes Dredge & Dock Corp, a principal claim of $11.7m
