Shipyard output in 2018 is set to fall to the lowest level in 12 years and half the record figure set in 2011, according to Clarksons Research Services.
Researcher George Warner says 80.7 million dwt of new ships are expected to be delivered to the world fleet this year.
He says this would be only 49% of the capacity arriving in 2011, largely reflecting a 50% decline in the orderbook since that time.
