IMO informed that its Sub-Committee on Carriage of Cargoes and Containers, being held from 11 to 15 September, will consider the latest research results on the potential instability of bauxite when carried as a ship’s cargo, that may lead to changes in industry rules about how such cargoes should be handled.

The UK MCA has issued a Marine Guidance Note in order to advise the industry of the circular issued by the International Maritime Organization (IMO) Sub-Committee on Carriage of Cargoes and Containers, CCC.1/Circ.2, on safe carriage of bauxite and raise awareness of the possible dangers of liquefaction associated with carriage of bauxite.

The Standard P&I Club informs that Malaysian authorities have temporarily suspended bauxite mining for a period of three months from mid-January 2016. This follows a period of significant mining activities for bauxite, especially in the Malaysian east coast state of Pahang, over recent years.

New Mars Report by The Nautical Institute refers to an incident involving bauxite liquefaction and cautions always to have the cargo tested for moisture content and to not transport it if moisture is above the transportable moisture limit.

Rio Tinto will expand output from one of the world’s premier bauxite deposits following approval of the $1.9 billion Amrun project. Amrun involves the construction of a bauxite mine and associated processing and port facilities on the Cape York Peninsula in north Queensland.

IMSBC Code Group A - Nickel Ore - Iron Ore Fines - Bauxite Cargo liquefaction may result in cargo shift and loss of stability; this has been the cause of a number of serious casualties during the last years and now liquefaction is being considered as a major hazard for bulk carriers.Liquefaction occurs when a cargo (which may not appear visibly wet) has a level of moisture in between particles. During a voyage, the ship movement may cause the cargo to liquefy and become viscous and fluid, which can lead to cargo flowing with the roll of the ship and potentially causing a dangerous list and sudden capsize of the vessel. Special consideration and precautions should be taken when loading a cargo which may liquefy.DNV GL has recenlty published an informative guideline for the design and operation of vessels with bulk cargo that may liquefy. The main risk for a vessel carrying cargo that may liquefy is shifting of the cargo.The following cargoes are subject to liquefaction:1. IMSBC Code Group AIn the IMSBC Code, the cargoes have been divided into three groups. Group A consists of cargoes that may liquefy. Group B are cargoes with a chemical hazard. Group C ...

CCC.1/Circ.2 IMO has issued a circular approved by IMOs Sub-Committee on Carriage of Containers and Cargoes (CCC) meeting (14 to 18 September 2015) to advise masters when to accept cargo of bauxite.The cargo of bauxite was declared as a Group C cargo under the International Maritime Solid Bulk Cargoes (IMSBC) Code. However, the Sub-Committee noted the information in the Bahamas document CCC 2/5/16 that loss of the vessel may have been caused by liquefaction of the cargo.The Sub-Committee also considered proposals made by Australia and co-sponsors with respect to the properties of bauxite and the need for the cargoes material properties to be further examined in order to ensure that the cargo can be carried safely.The Sub-Committee concluded that:there is a need to raise awareness, despite the efforts to date made by the Member clubs of the International Group of P&I Clubs, of the possible dangers of liquefaction associated with carriage of bauxitethe potential for bauxite to liquefy is not specifically addressed in the IMSBC Code, since it is only classified as Group C cargo;if a Group A cargo is shipped with moisture content in excess of its transportable moisture limit (TML) there is a risk of cargo shift, which ...
