Maintenance and Engineering Department, Fleet Maintenance and EngineeringGroup (Visitors shall inform the Fleet Maintenance and Engineering Group by threedays before the visit except for emergency cases). Criteria for personnel who visit
the vessels for other purposes (e.g. ship tour) shall be determined separately.

Procedures to be carried out by Visitors
By 14 days before visiting• Number of visiting personnel and days of visit shall be essential minimum.

NoteUpon receiving the report from the visitor, the MarE3 Operations Department will
determine availability of visiting. In case the person has any symptoms, a doctor’s
diagnosis is required (at the visitor’s cost), and the MarE3 Operations Department
will determine based on the diagnosis. In case the person is diagnosed to be “notinfectious”, the visiting will be permitted, in principle. Even if the person is diagnosed
to be “infectious”, the visiting will be permitted without another diagnosis as far as
the recovery period specified in the latest MLHW guideline is over by the day beforevisiting.
High fever, chill or headache WITHOUT any other cold-like symptoms such as
cough, pain in the throat and breathing difficulty within three days after COVID-19
vaccination (the day of vaccination and two days after that) are likely to be sideeffects of vaccination. In such a case, reporting to the Fleet Operations Group is not
required.
The above standards may be changed based on the policies of the administrative
agencies and JAMSTEC in the future. In addition, the above standards will remain
effective until a new revised standard is issued or an instruction to cancel application
is issued. If you have any questions, please contact the appropriate department ofMarE3.
