MSC.1-Circ.1440 - Illustrations Of Segregation Of Cargo Transport Units On Board Containerships And Ro-Ro Ships (Secretariat)

MSC.1/Circ.1440 1 June 2012

ILLUSTRATIONS OF SEGREGATION OF CARGO TRANSPORT UNITS ON BOARD CONTAINERSHIPS AND RO-RO SHIPS
1 The Maritime Safety Committee, at its ninetieth session (16 to 25 May 2012), having considered the proposal by the Sub-Committee on Dangerous Goods, Solid Cargoes and Containers, at its sixteenth session, with regard to illustrations of segregation of cargo transport units on board containerships and ro-ro ships, which apply to the carriage of packaged dangerous goods in pursuance of the requirements of SOLAS chapter VII and the relevant provisions of the IMDG Code, approved the illustrations of segregation of cargo transport units on board containerships and ro-ro ships, as set out in the attached annex.
2 Member Governments are invited to bring the illustrations of segregation of cargo transport units on board containerships and ro-ro ships, as set out in the annex, to the attention of competent authorities, seafarers and others concerned, taking into account the voluntary application date of 1 January 2013 of amendment 36-12 of the IMDG Code pending its envisaged mandatory entry-into-force date of 1 January 2014.

ANNEX
ILLUSTRATIONS OF SEGREGATION OF CARGO TRANSPORT UNITS ON BOARD CONTAINERSHIPS AND RO-RO SHIPS
1 Scope
1.1 The segregation requirements applicable to containerships with hatch covers, hatchless containerships and ro-ro ships are provided in 7.4.3 and 7.5.3 of the IMDG Code. To facilitate familiarization with these requirements and to support training of relevant personnel, the following illustrations have been developed. It should be noted that only the relevant tables in the IMDG Code are legally binding. In case of any discrepancy, they shall take precedence over the illustrations in this circular.
1.2 This circular contains illustrations of segregation of:
- containers on board containerships with hatch covers (see section 2 of this circular); - containers on board hatchless containerships (see section 3 of this circular); and - cargo transport units on board ro-ro ships.
2 Illustrations of segregation of containers on board containerships with hatch covers
2.1 The illustrations of this section apply to the segregation of containers which meet the definition of a container within the term of the International Convention for Safe Containers (CSC) 1972, as amended, and are transported on deck and in the cargo holds of containerships or on deck and in the cargo holds of other types of ships provided that these stowage positions are properly fitted to give a permanent stowage of containers during transport1.
2.2 To determine locations in which containers are not permitted to contain dangerous goods that are incompatible with those in a reference container, the following method applies: container spaces (such as one container space, two container spaces) are identified in accordance with the applicable segregation provisions in the direct fore-and-aft and athwartships directions from the reference container. Lines are projected between the outermost corners of the containers occupying these spaces as shown in the figure. Containers located partially or completely between these lines and the reference container shall not contain dangerous goods that are incompatible with those in the reference container.
2.3 The deck/hold layout used for the illustrations is:
- two 20' containers stowed in a 40' container space - distance between two 40' container spaces is 2 ft/60 cm
1 For containerships with partly hatchless container cargo spaces, the illustrations of section 3 apply to such spaces.

Note 1: All bulkheads and decks shall be resistant to fire and liquids. Note 2: When an illustration has more than one reference container, only one should be used when interpreting the illustration. When an illustration contains several reference containers, they have to be considered as different examples.

3 Illustrations of segregation of containers on board hatchless containerships
3.1 The illustrations of this section apply to the segregation of containers which are transported on board hatchless containerships provided that stowage positions are properly fitted to give permanent stowage of the containers during transport2.
3.2 To determine locations in which containers are not permitted to contain dangerous goods that are incompatible with those in a reference container, the following method applies: container spaces (such as one container space, two container spaces) are identified in accordance with the applicable segregation provisions in the direct fore-and-aft and athwartship directions from the reference container. Lines are projected between the outermost corners of the containers occupying these spaces as shown in the figure. Containers located partially or complete completely between these lines and the reference container shall not contain dangerous goods that are incompatible with those in the reference container.
2 For partly hatchless containerships with hatch-covered container cargo spaces, the illustrations of section 2 apply to such spaces.

4 Illustrations of segregation of cargo transport units on board ro-ro ships
4.1 The illustrations of this section apply to the segregation of cargo transport units which are transported on board roll-on/roll-off ships or in roll-on/roll-of cargo spaces3.
4.2 To determine locations in which cargo transport units are not permitted to contain dangerous goods that are incompatible with those in a reference cargo transport unit, the following method applies: locations where incompatible dangerous goods are not permitted with respect to the referenced cargo transport unit are first determined in the direct fore and aft and athwartships directions. The relevant segregation distances to be considered in both directions are defined in metres as shown in the figure. Cargo transport units located partially or completely within these distances from the reference cargo transport unit shall not contain dangerous goods that are incompatible with those in the reference cargo transport unit.
4.3 The standard dimension of a cargo transport unit used for the illustrations is:
- length: 12 m - width: 2.50 m
3 For ro-ro ships which carry containers on decks or in holds, the illustrations of section 2 apply to such spaces.
MSC.1/Circ.1440 Annex, page 39
I:\CIRC\MSC\01\1440.doc
4.4 Explanation of the segregation terms
Note 1: All bulkheads and decks shall be resistant to fire and liquid. Note 2: When an illustration has more than one reference cargo transport units, only one should be used when interpreting the illustration. When an illustration contains several reference cargo transport units, they have to be considered as different examples.
