Singapore-based shipmanager Synergy Group has warned of a “time bomb” in crewing during the coronavirus pandemic and called for collective crew changes at main trading hubs.

With three billion people under lockdown measures globally in a bid to contain the Covid-19 pandemic, changing crew has become extremely difficult for the shipping industry.

In a press release, Synergy founder and chief executive Rajesh Unni said a potential solution is for shipowners and shipmanagers to work with other stakeholders to change crews at select key ports in standardised procedures.
