The UK government has updated guidance for ship masters and operators during the coronavirus (COVID-19) pandemic.
It said all vessels should carry adequate medical supplies, equipment and personal protective equipment (PPE).
Anyone with a new, continuous cough or a high temperature should be denied embarkation.
Once on board, everyone should know to whom they report if they develop symptoms.
Anyone who does develop symptoms should be confined to their cabin.
Three robbers briefly held a crew member hostage after boarding a vessel in Macapa Anchorage, Brazil.
The seafarer was seized as he headed forward to check the activity of a small boat spotted near the anchored vessel’s bow.
When he failed to respond to radio calls from the officer of the watch (OOW) an alarm was raised.
The crew were mustered, prompting the robbers to release the seafarer and flee the vessel. They took with them stolen ship’s stores and the seafarer’s two-way radio.
The anchored vessel, which was unidentified in initial reports, was boarded just before midnight on March 16.
