Canadian tonnage provider Seaspan Corp has increased its earnings at a time when vessel operators are being hammered by the rate slump.

The owner has 153 ships on long-term charters to lines, with another 42 still on order at shipyards.

The company’s parent Atlas Corp said in a US securities filing that Seaspan’s adjusted Ebitda in the third quarter was $303m, up from $255.2m
