[post_content] => The International Maritime Organisation’s (IMO) Marine Environment Protection Committee (MEPC) and Maritime Safety Committee (MSC) have recently agreed a series of amendments to the International Code for the Construction and Equipment of Ships Carrying Dangerous Chemicals in Bulk (IBC Code) that are expected to enter into force on 1 January 2021.
The revisions affect Chapters 17 (the summary of minimum requirements), 18 (the list of products to which the Code does not apply), 19 (the index of products carried in bulk) and 21 (the criteria for assigning carriage requirements for products subject to the Code).
These revisions, which followed on from lengthy work by the various sub-committees and the Group of Experts on the Scientific Aspects of Marine Pollution (GESAMP) were formally adopted by MEPC at its 74th session in May and by MSC at its 101st session in early June.
The International Parcel Tankers Association (IPTA) provides this brief summary of the impact of the revisions:
“Chapter 21 of the IBC Code, which sets out the criteria for the assignment of carriage requirements, has been extensively amended to ensure that measures imposed are appropriate for the degree of hazard posed by individual products. Chapters 17 and 18, which list the carriage requirements for products, have been revised to take into account the new criteria, as well as some revised GESAMP Hazard Profiles. While there had initially been some concern that a number of high-volume products could result in Ship Type 1, that has not been the case. The most significant effect of the changes will be a steep increase in the number of products classed as Toxic, with the various requirements that such a classification brings.”
TOXIC IN TRANSPORT
The changes to the IBC Code are, in fact, quite extensive. Milbros Shipping notes that the handling and safety requirements will change for 86 per cent of the 845 products listed in Chapters 17 and 18. While most changes can be considered insignificant, Milbros warns that some cargoes that have been listed on a ship’s certificate of fitness (COF) may no longer be allowed to be carried. Milbros has already updated its online tool to reflect the changes.
In addition, the number of cargoes identified as ‘toxic’ in Chapter 17 will rise from 231 to 429. New additions to the list of toxic products include some commonly carried cargoes such as methanol, methyl isobutyl ketone (MIBK), diethylene glycol, nonyl alcohol, n-propyl alcohol and octanol.
Substances subject to the requirements for toxic production bring with them specifications for the location of exhaust openings, the provision of vapour return lines and pressure/vacuum valves, and stowage restrictions (specifically, not adjacent to fuel tanks). There is concern in the sector that the addition of some high-volume products (most notably methanol) to the list will result in an effective loss of cargo capacity in the fleet.
Other changes have been occasioned by an amendment to Annex II of the International Convention for the Prevention of Pollution from Ships (Marpol), resulting from numerous reports of residues of high viscosity and persistent floating substances washing up on beaches in northern and western Europe.
New paragraphs will be added to Regulations 13 in Annex II to require prewash and discharge of residue/water mixture generated during the prewash to a reception facility, for 44 specific products, in specified areas (north-west Europe, Baltic Sea, western European waters and Norwegian Sea). Those products are certain vegetable oils and paraffin-like cargoes that have a high viscosity and/or a high melting point. They will be indicated in column o of chapter 17 of the IBC Code, referencing a new paragraph 16.2.7 in the Code.
During IPTA’s Chemical and Product Tanker Conference in London in March, delegates were alerted to the fact that IMO is keeping an eye on this topic; if the problem of waxy residues washing up on beaches persists, then another 80 products may be added to the list.
THE OTHER CODES
MSC also adopted a consolidated edition of the International Maritime Solid Bulk Cargoes Code (IMSBC Code), Amendment 05-19. The new edition includes a number of revised schedules, including an important change in the new individual schedule for bauxite fines as a Group A cargo. While these changes too are expected to enter into force on 1 January 2021, governments may apply them in whole or in part from 1 January 2020.
Somewhat further ahead are amendments to parts A and A-1 of the International Code of Safety for Ships using Gases or other Low-flashpoint Fuels (IGF Code), which are expected to enter into force on 1 January 2024. These include regulations on loading limits for liquefied gas fuel tanks, regulations for fuel distribution outside of machinery space, regulations for internal combustion engines of piston type and fire protection for fuel storage hold space, and amendments relating to the protection of the fuel supply for liquefied gas fuel tanks, aimed at preventing explosions.
