Some shipowners claim retrofitting of exhaust gas scrubbers is on schedule for IMO 2020, but others may not be so lucky — due to poor planning.

The New York-listed Greek owner of 10 capesize bulkers expects China's YiuLian Dockyards to install scrubbers on five ships by 20 December for $16m in total, he said.
