According to Police Commissioner Samsu Wirman, chief of local police, the vessel, with ~1600 tourists on board, was located 1.5 nautical miles away from the port. He revealed that the Semarang city regional police commander had ordered them "to communicate with the port authority to not allow this cruise ship to dock."
Head of the Semarang city health agency Mochamad Abdul Hakam said that a team of the health office of Tanjung Emas Port had been deployed "to conduct medical checkups of all passengers."
In case the team finds a condition with the people under observation, all guests would be kept on the cruise ship. As an emergency measure, the agency had prepared a medical team at the cruise port that is ready to take such actions in the event of travellers disembarking and requiring immediate treatment.
