Annex Amendments to the International Code for the Construction and Equipment of Ships Carrying Dangerous Chemicals in Bulk (IBC Code)

 These amendments have been consolidated into IBC Code

Chapter 1 General

  1 New paragraphs 1.3.37 and 1.3.38 are added as follows:

  • "1.3.37 Purging means the introduction of inert gas into a tank which is already in an inert condition with the object of further reducing the oxygen content; and/or reducing the existing hydrocarbon or other flammable vapours content to a level below which combustion cannot be supported if air is subsequently introduced into the tank.

  • 1.3.38 Gas-freeing means the process where a portable or fixed ventilation system is used to introduce fresh air into a tank in order to reduce the concentration of hazardous gases or vapours to a level safe for tank entry."

Chapter 2 Ship Survival Capability and Location of Cargo Tanks

  2.2 Freeboard and intact stability

  2 The title of section 2.2 is amended to read:

  • "Freeboard and stability"

  3 A new subparagraph 2.2.6 is added as follows:

  • "2.2.6 All ships, subject to the Code, shall be fitted with a stability instrument, capable of verifying compliance with intact and damage stability requirements, approved by the Administration having regard to the performance standards recommended by the Organizationfootnote:

  • .1 ships constructed before 1 January 2016 shall comply with this requirement at the first scheduled renewal survey of the ship on or after 1 January 2016 but not later than 1 January 2021;

  • .2 notwithstanding the requirements of 2.2.6.1, a stability instrument fitted on a ship constructed before 1 January 2016 need not be replaced provided it is capable of verifying compliance with intact and damage stability, to the satisfaction of the Administration; and

  • .3 for the purposes of control under regulation 16 of MARPOL Annex II, the Administration shall issue a document of approval for the stability instrument.

  4 A new subparagraph 2.2.7 is added as follows:

  • "2.2.7 The Administration may waive the requirements of paragraph 2.2.6 for the following ships provided the procedures employed for intact and damage stability verification maintain the same degree of safety, as being loaded in accordance with the approved conditionsfootnote. Any such waiver shall be duly noted on the International Certificate of Fitness referred to in paragraph 1.5.4:

  • .1 ships which are on a dedicated service, with a limited number of permutations of loading such that all anticipated conditions have been approved in the stability information provided to the master in accordance with the requirements of paragraph 2.2.5;

  • .2 ships where stability verification is made remotely by a means approved by the Administration;

  • .3 ships which are loaded within an approved range of loading conditions; or

  • .4 ships constructed before 1 January 2016 provided with approved limiting KG/GM curves covering all applicable intact and damage stability requirements.

Chapter 8 Cargo Tank Venting and Gas-Freeing Arrangements

  5 In paragraph 8.1.5, the references to "SOLAS regulations II-2/4.5.3 and 4.5.6" are replaced by references to "SOLAS regulations II-2/4.5.3, 4.5.6 and 16.3.2".

  6 A new paragraph 8.5 is inserted as follows:

  • "8.5 Cargo tank purging

  • When the application of inert gas is required by 11.1.1, before gas-freeing, the cargo tanks shall be purged with inert gas through outlet pipes with cross-sectional area such that an exit velocity of at least 20 m/s can be maintained when any three tanks are being simultaneously supplied with inert gas. The outlets shall extend not less than 2 m above the deck level. Purging shall continue until the concentration of hydrocarbon or other flammable vapours in the cargo tanks has been reduced to less than 2% by volume."

  7 The existing paragraph 8.5 and subparagraphs 8.5.1, 8.5.2 and 8.5.3 are renumbered as paragraph 8.6 and subparagraphs 8.6.1, 8.6.2 and 8.6.3, respectively, and, in the renumbered paragraphs 8.6.2 and 8.6.3 the referenced paragraph numbers "8.5.1", "8.5.1.2" and "8.5.1.3" are replaced with "8.6.1", "8.6.1.2" and "8.6.1.3", respectively.

Chapter 9 Environmental Control

  8 The chapeau of paragraph 9.1.3 is replaced by the following:

  • "9.1.3 Where inerting or padding of cargo tanks is required by this Code in column "h" of chapter 17:"

Chapter 11 Fire Protection and Fire Extinction footnote

  9 Subparagraph 11.1.1.1 is replaced by the following:

  • "11.1.1.1 Regulations 10.8 and 10.9 shall not apply;"

Chapter 15 Special Requirements

  10 The following footnote is added at the end of paragraph 15.13.3.2:
  • "* Refer to MSC-MEPC.2/Circ.14 on Products requiring oxygen-dependent inhibitors."

  11 Paragraph 15.13.5 is replaced by the following:

  • "15.13.5 When a product containing an oxygen-dependent inhibitor is to be carried:

  • .1 in a ship for which inerting is required under SOLAS regulation II-2/4.5.5, as amended, the application of inert gas shall not take place before loading or during the voyage, but shall be applied before commencement of unloadingfootnote;

  • .2 in a ship to which SOLAS regulation II-2/4.5.5, as amended, does not apply, the product may be carried without inertion (in tanks of a size not greater than 3,000 m3). If inertion is to be applied on such a ship, then the application of inert gas shall not take place before loading or during the voyage, but shall be applied before commencement of unloadingfootnote.

Chapter 17 Summary of Minimum Requirements

  12 The explanatory notes for "Tank environment control (column h)" are replaced by the following:

  • "Tank environmental (column h)

    • Inert: inerting (9.1.2.1)
    • Pad: liquid or gas padding (9.1.2.2)
    • Dry: drying (9.1.2.3)
    • Vent: natural or forced ventilation (9.1.2.4)

    • (iii) * in accordance with a loading condition which lies within an approved range of conditions defined in the approved loading manual referred to in (i) above; or

    • (iv) * in accordance with a loading condition verified using approved critical KG/GM data defined in the approved loading manual referred to in (i) above;

  • .3* in accordance with the loading limitations appended to this Certificate.

 Where it is required to load the ship other than in accordance with the above instruction, then the necessary calculations to justify the proposed loading conditions shall be communicated to the certifying Administration who may authorize in writing the adoption of the proposed loading condition.
