Singapore's shipyards will remain open during the country's one-month lockdown period that goes into effect at midnight on Tuesday.

Shipyards have been given in principle notice from the Ministry of Trade that they may continue their shipbuilding and repair activities as marine and offshore engineering have been assessed as being an essential service.

The notice ends the uncertainty shipyards and their shipowner clients have faced since last Friday, when Prime Minister of Singapore Lee Hsien Loong announced restrictive measures in the country's fight against the virus.
