Annex 1 Draft Individual Schedule for Iron Ore Fines

  IRON ORE FINES

  • .1 10% or more of fine particles less than 1 mm (D10 ≤ 1 mm); and

  • .2 50% or more of particles less than 10 mm (D50 ≤ 10 mm).

 Notwithstanding the above provision, iron ore fines where the total goethite content is 35% or more by mass may be carried in accordance with the individual schedule for "IRON ORE", provided the master receives from the shipper a declaration of the goethite content of the cargo which has been determined according to internationally or nationally accepted standard procedures.

  Description

 Iron ore fines vary in colour from dark grey, rusty red to yellow and contain hematite, goethite and magnetite with varying iron content.

 IRON CONCENTRATE is a different cargo (See individual schedule for "Mineral Concentrates")

  Weather precautions

 When a cargo is carried in a ship other than a specially constructed or fitted cargo ship complying with the requirements in subsection 7.3.2 of this Code, during loading and unloading operations, the following provisions shall be complied with:

  • .1 the moisture content of the cargo shall be kept less than its TML during loading operations and the voyage;

  • .2 unless expressly provided otherwise in this individual schedule, the cargo shall not be handled during precipitation;

  • .3 unless expressly provided otherwise in this individual schedule, during handling of the cargo, all non-working hatches of the cargo spaces into which the cargo is loaded or to be loaded shall be closed;

  • .5 the cargo in a cargo space may be discharged during precipitation provided that the total amount of the cargo in the cargo space is to be discharged in the port.

  Loading

 Trim in accordance with the relevant provisions required under sections 4 and 5 of the Code. As the density of the cargo is high, due consideration shall be given to ensure that tanktop is not overstressed during voyage and during loading by a pile of the cargo.

  Precautions

 Loading rates of this cargo are normally very high. Due consideration shall be given to the ballasting operation in developing the loading plan required by SOLAS regulation VI/7.3. Bilge wells shall be clean, dry and protected as appropriate to prevent ingress of the cargo.

  Ventilation

 No special requirements

  Carriage

 Cargo hold bilges shall be sounded at regular intervals and pumped out, as necessary. The appearance of the surface of this cargo shall be checked regularly during voyage, as far as practicable. If free water above the cargo or fluid state of the cargo is observed during voyage, the master shall take appropriate actions to prevent cargo shifting and potential capsize of the ship, and give consideration to seeking emergency entry into a place of refuge.
