  • When working in exposed areas such as the rear deck, be sure to obtain the permission of the Captain (or Chief Officer) and take all possible safety measures, such as wearing life jackets.
  • Never go out on the deck alone at night. It is extremely dangerous, especially if you are seasick or have been drinking alcohol.

  • In case of an emergency, please contact the Bridge. If a fire breaks out in your room or laboratory, alert the ship by making an announcement via the nearest telephone.

In addition, JAMSTEC, the operating company, and the crew of the ship will not be liable for any damage or loss of materials and equipment brought in by the researcher after the ship is loaded and during land transportation before and after the cruise. In preparation, we recommend that researchers make all arrangements for required insurance on their own responsibility (travel accident insurance, freight insurance, student insurance, etc.).

7. Communication with Land

  • Each vessel has provisions for marine telephones, Inmarsat telephones, fax machines, and email. For details, please see the detailed guide for each ship.

  • Raw garbage (food scraps, etc) are crushed with a disposer and discharged outboard through a pump, so never put anything into the raw garbage that could be a source of mechanical failure (pin caps, can pull rings, toothpicks, disposable chopsticks, and other solids).
  • It is the responsibility of the researchers who have brought onboard their own medical equipment (syringe, needle, etc.) for proper disposal of such items. The researchers are also responsible for the disposal of any other consumables of the medical equipment used in measurements. This means collection and disposal at their home institution.

10. Baths/Toilets

11. Laundry

  • The washing machine and dryer can be used except late at night and early in the morning. Please note that depending on the research being done, they may be temporarily unavailable. Please follow all instructions from the ship.
  • Never use the “Water Drainage” (水の流しっぱなし と 流しすすぎ) setting while using the washing machine.
  • Once the cycle is finished, please remove your laundry from the washing machine or dryer immediately. Others may be waiting to use the machines, so please be considerate.
