This one is aimed to provide readers with the clear technical explanation of how to monitor coal cargoes coming from Indonesia; it is relatively small booklet containing the checklist prepared with the intention to provide required assistance in reduction of the risks commonly associated with the self-heating of such cargoes.

Subject incidents have been quite frequent in the recent decades and this frequency continues to be constantly rising today. This problem of shipping is considered to be primarily relating to the nature of the coal cargoes and in fact may easily get exacerbated by the ways these cargoes are being handled prior to and in the course of the loading. The recommendations related to the safe coal transportation are outlined in the IMSBC Appendix I mandatory since 2011. The present checklist is mainly intended as the guidance for the ship owners, marine surveyors, shippers and charterers, crew members and all other parties engaged in the loading/discharge of subject cargoes.

Note that it shall not be considered a substitution to the Code recommendations...
