国际海运固体散货规则A类及修订C类分类规则现已强制生效——易液化的铝矾土货物载运

来源:The UK P&I Club @ 2021.02.02

2020年国际海运危险货物规则修订版已于202111日起生效。

20151月超灵便型散货船BULK JUPITER倾覆,该事件造成18位海员死亡,IMO集装箱与货物运输(CCC)分委会于20159月第二次会议上注意到货物液化可能会导致船舶倾覆。会议通函CCC.1/Circ.2《易液化的铝矾土货物载运》于会议期间发布,引发业内对于铝矾土运输过程中水分可能引发风险的关注。尽管铝矾土在《国际海运固体散货规则》中被归为C类货,规则并未对此种货物发生液化的可能性进行特别说明。

全球铝矾土工作组(GBWG)协同主管部门进行后续工作,指出有必要对易液化和不可液化的铝矾土货物进行明确区分。

基于以上工作,《国际海运固体散货规则》经修订,A类货物中新增了“BAUXITE FINES/铝矾土粉”,现有C类铝矾土货物分类表也被修订。这两个分类表分类主要基于粒径分布(PSD),简而言之,与铝矾土相比,尽管铝矾土粉的排水性能也要考虑在内,但是含有更高比例细颗粒的铝矾土粉被允许装载。修订规则于2020年公布,现已生效。

修订规则包括《国际海运固体散货规则》的如下修改:

①铝矾土适运水分极限测试程序;

②铝矾土A类货分类表新增品名“铝矾土粉”;

③铝矾土C类货分类表的修改。

From 1st January 2021 the revised IMDG Code 2020 enters force.


Following the loss of the Supramax bulk carrier BULK JUPITER in January 2015, with the tragic loss of 18 lives, the IMO Sub-Committee on the Carriage of Cargoes and Containers (CCC), at its second session in September 2015 noted that the loss of the ship may have been caused by liquefaction of the cargo. Circular CCC.1/Circ.2 "Carriage of Bauxite which may Liquefy" was issued at that time to raise awareness to the potential risks posed by moisture in the carriage of Bauxite. Although Bauxite is described in the IMSBC Code as a Group C cargo, the potential for this cargo to liquefy was not specifically addressed in the Code.


Subsequent work undertaken by the industry Global Bauxite Working Group (GBWG) in conjunction with competent Authorities indicated that there was a need to draw a distinction between Bauxite cargoes that can liquefy and those that do not.


As a result of the above work the IMSBC Code was amended to include a new Group A cargo ‘BAUXITE FINES’ and the existing schedule for ‘BAUXITE’ classified as Group C was revised. The two schedules are primarily based on a particle size distribution (PSD) criterion, where, in simple terms, bauxite fines are permitted loaded with a larger percentage of fine particles compared to bauxite, although drainage properties also come into consideration. The amended Code was published in 2020 and has now entered force.


The revised code includes amendments to the IMSBC Code as follows:


1. Test procedure for determining the TML for Bauxite;


2. Schedule for Bauxite Group A having the shipping name "BAUXITE FINES";


3. Amendments to the schedule for BAUXITE Group C.
