SOLAS – Amendments to the IMSBC Code (Amendment 02-13) – Reminder.

In June 2013 the IMO Maritime Safety Committee adopted Resolution MSC.354(92) specifying amendments to the International Maritime Solid Bulk Cargoes (IMSBC) Code. Contracting governments to the SOLAS Convention have been able to apply the amendments in whole or in part on a voluntary basis since 1 January 2014. Mandatory compliance with the amended IMSBC Code requirements will commence on 1 January 2015.

The IMSBC Code is subject to updates every two years to reflect changes in the nature and variety of solid bulk cargoes presented for shipment and advances in expert understanding regarding the safest ways to carry established solid bulk cargoes. Amendment 02-13 is the second amendment to the IMSBC Code since compliance became mandatory on 1 January 2011. The principal changes are summarised below:

Section 1.7 – Definitions

The definition of a “Competent Authority” now includes a requirement for the Competent Authority to operate independently of the shipper. There have been occasions in the past where the shipper and Competent Authority have been closely related, leading to a possible conflict of interests.

Section 3 – Safety of personnel and ship

Sub-section 3.6 – Cargo under in-transit fumigation; two new paragraphs of precautionary measures have been added to address the hazard of fumigant gases entering occupied spaces during in-transit fumigation.

Section 4 – Assessment of acceptability of consignments for safe shipment

Sub-section 4.3 – Certificates of test; the requirement in paragraph 4.3.2 for the shipper to provide a signed certificate of the Transportable Moisture Limit (TML) and a signed certificate or declaration of the moisture content has been expanded. There is now a requirement for such documentation to be issued by an entity recognised by the Competent Authority at the port of loading.

A new paragraph 4.3.3 has been added stating that when a concentrate or other cargo that may liquefy is carried, the shipper shall have in place procedures for sampling, testing and controlling the moisture content of the cargo to ensure it is below the TML while onboard the vessel. The procedures are to be approved, and their implementation checked, by the Competent Authority at the port of loading. A copy of the approval document issued by the Competent Authority is to be provided to the Master or his representative.

A new paragraph 4.3.4 addressing the problem of uncovered barges with low freeboard transporting Group A cargoes to other vessels has been added; shippers are to include measures to protect cargo on barges from precipitation and water ingress in the procedures required by paragraph 4.3.3.

Sub-section 4.4 – Sampling procedures; there is a new paragraph 4.4.3 requiring shippers to facilitate access to stockpiles by the ship’s nominated representative for the purposes of inspection and sampling for subsequent testing. This provision is particularly welcome and should ease one of the greatest hindrances currently encountered when precautionary P&I surveys of Group A cargoes are arranged.

Section 7 – Cargo which may liquefy

In sub-section 7.2 – Conditions for hazards; the existing paragraph 7.2.2 has been replaced with the sentence “Liquefaction does not occur when the cargo consists of large particles or lumps and water passes through the spaces between the particles and there is no increase in water pressure”.

Section 8 – Test procedures for cargoes which may liquefy

Sub-section 8.4 – Complementary test procedures for determining the possibility of liquefaction; additional guidance has been added to this section which describes how to conduct a “can test”, advising that if a sample remains dry following such a test, the moisture content of the material may still exceed the TML.

Section 9 – Materials possessing chemical hazards

Paragraph 9.2.3 – Materials Hazardous only in Bulk (MHB); an updated definition has been added along with details of the chemical hazards that would cause a material to be classified as a MHB.

Appendix 1 – Individual schedules of solid bulk cargoes

A number of changes have been made to the following existing cargo schedules:

  • Ammonium Nitrate UN 1942
  • Ammonium Nitrate Based Fertilizer UN 2067
  • Ammonium Nitrate Based Fertilizer UN 2071
  • Ammonium Nitrate Based Fertilizer (non-hazardous)
  • Calcium Nitrate UN 1454
  • Calcium Nitrate Fertilizer
  • Charcoal
  • Ferrous Metal Borings, Shavings, Turnings or Cuttings UN 2793
  • Metal Sulphide Concentrates
  • Peat Moss
  • Sand
  • Seed Cake UN1386 (b)
  • Seed Cake (non-hazardous)
  • Silicomanganese (low carbon)
  • Sulphur (formed, solid)

The following new schedules have been added to Appendix 1 of the Code:

  • Alumina Hydrate, classified as a Group A and B cargo, and also a MHB.
  • Aluminium Smelting / Remelting By-Products, Processed, classified as a Group A and B cargo, and also a MHB.
  • Clinker Ash, Wet, classified as a Group A and B cargo, and also a MHB.
  • Coal Tar Pitch, classified as a Group B cargo, and also a MHB.
  • Coarse Iron and Steel Slag and its Mixture, classified as a Group C cargo.
  • Crushed Carbon Anodes, classified as a Group C cargo.
  • Grain Screening Pellets, classified as a Group C cargo.
  • Granulated Nickel Matte (Less Than 2% Moisture Content), classified as a Group B cargo, and also a MHB.
  • Gypsum Granulated, classified as a Group C cargo.
  • Ilmenite (Rock), classified as a Group C cargo.
  • Ilmenite (Upgraded), classified as a Group A cargo.
  • Nickel Ore, classified as a Group A cargo; Members are reminded of the Club’s mandatory notification and survey requirement regarding the loading and carriage of this cargo, as detailed in Notice to Members No.14 2013/2014 – Dangers of Carrying Nickel Ore from Indonesia and the Philippines.
  • Sand, Heavy Mineral, classified as a Group A cargo.
  • Silicon Slag, classified as a Group C cargo.
  • Solidified Fuels Recycled From Paper and Plastics, classified as a Group B cargo, and also a MHB.
  • Wood Torrefied, classified as a Group B cargo, and also a MHB.

Grain Screening Pellets and Wood Torrefied have been added to the list of non-cohesive cargoes detailed in Appendix 3. The Index in Appendix 4 has been updated to include the additional cargoes included in Appendix 1. The material “Spodumene” has also been added to the Index with a reference directing the reader to the schedule for Sand.

The foregoing is a summary of some of the important changes to the IMSBC Code set out in Amendment 02-13. Full details of all amendments can be found in Resolution MSC.354(92) Amendments to the International Maritime Solid Bulk Cargoes (IMSBC) Code.

Members are reminded to ensure their vessels comply with the amended IMSBC Code requirements from 1 January 2015 if they are not already doing so in whole or in part in accordance with flag or port state requirements.
