P&I CLUB GUIDANCE ON PROPER COAL CARGO CARRIAGE
According to the Britannia Club P&I Club, due to its origins as a carbonaceous sedimentary rock formed by geological processes applying pressure to the remains of plant material over time, coal comes in many different forms and the term covers a relatively wide range of cargoes. Therefore, its properties and the associated hazards also vary significantly depending on the specific form of coal being carried as cargo. However, all coal cargoes require certain precautions upon loading, and monitoring during voyage.
Coal regulation As a potentially hazardous bulk cargo, Britannia says it is essential that coal is always loaded, carried and discharged in accordance with the requirements of the International Maritime Solid Bulk Cargoes (IMSBC) Code. These requirements should be closely followed by both ship and shore management.
Liquefaction With the exception of coal cargoes classed as Group B only, the cargo declaration should be accompanied by documentation relevant to the moisture content (MC) of cargo and its TML, issued by an entity that is recognised by the competent authority of the port of loading.
The IMSBC Code stipulates that if a Group A cargo has been exposed to significant rain or snow between the time of testing and the date of completion of loading, the shipper is responsible to ensure that the MC of the cargo is still less than its TML, and that evidence of this is provided to the ship’s Master as soon as practicable. If the cargo is loaded onto the ship from barges, the shipper should include procedures to protect the cargo on the barges from any precipitation and water ingress.
Cargo declaration The shipper’s cargo declaration must be provided in accordance with the requirements of the IMSBC Code, in particular with regard to the cargo properties and the associated hazards. The declaration must include a section clearly stating whether the cargo of coal is liable to emit methane, or self-heat. In such cases, the Special Precautions in the IMSBC Code for “coals emitting methane” and “self-heating coals,” respectively, must be taken.
