Customs' group manager maritime Stephen Waugh says the process will carry very low public health risk.
"The crew will be transported at a time that will minimise the risk of coming into contact with members of the public," he says.
"Customs will maintain presence at the port throughout the operation, with the support of additional security personnel, and the Police Maritime Unit maintaining watch over the water."
Perimeter fencing will cordon off the area where the Viking Bay will dock to remove public access, with the authorities stepping up security at the wharf and on-water patrols.
All Government and CentrePort staff that interact with the vessel or crew are vaccinated, and will work in line with health and safety protocols including IPC and PPE requirements.
