19.5 CONSTRUCTION/CERTIFICATION REQUIREMENTS TO MAINTAIN MASS
EQUIVALENCE
19.5.1 Scuppers and Drains:
n The scupper and drainage arrangements are to be directed overboard with no connections to internal spaces.
19.5.2 Electrical Equipment:
n Electrical equipment installed in the cargo area should be of the certified safe type for the cargo being carried
or be capable of being securely isolated during the carriage of packaged dangerous goods.
19.5.3 Structural Fire Protection:
n Bulkheads forming boundaries containing fuel tanks, engine spaces and [in the event of partial manned
operations] accommodation spaces are to be insulated to A-60 standard unless the dangerous goods are
stowed three metres from such bulkheads and boundaries.
19.5.4 Vessel Certification. Prior to carrying dangerous goods, the vessel should be surveyed, and a dangerous goods
Document of Compliance issued. A risk based assessment should be undertaken in consideration of the size
categorisation (Paragraph 4.7) and level of autonomy (Table 1-4).
19.5.5 Operators are recommended to undertake their own safety assessment before applying for a Document of
Compliance for the Carriage of Dangerous Goods; this assessment procedure should be discussed with the
Administration. This may consider specific requirements for the vessel including the carriage of additional safety
equipment, (i.e. in MASS operations for remote sensing and reporting), additional emphasis on structural fire
protection, automated fire suppression, separation between dangerous goods and control spaces. It may be
necessary for the operator to submit a safety case.
19.5.6 This survey may only be undertaken by a RO and will be valid for a determined period or specific operation. Upon
successful completion of a survey, a Document of Compliance for the Carriage of Dangerous Goods will be issued
to the vessel indicating the Class of goods that can be carried with a list of equipment fitted.
19.6 OPERATIONAL CONSIDERATIONS
19.6.1 Operator Training as prescribed in MASS certification (See Chapter 2 of this Code)
n The MASS operating authority should undergo training in the carriage of dangerous goods and the IMDG
Code, commensurate with their responsibilities, and records kept of the training undertaken.
19.6.2 Stowage and Segregation requirements [in meeting MASS equivalency]:
n Dangerous goods are only to be carried on deck or in internal MASS certified stowages;
n They should be secured to the vessels to prevent movement during the voyage;
n The stowage and segregation requirements of the IMDG Code should apply;
n Packaging (including portable tank and IRCC) should be commensurate with the intended MASS operations
and take due cognizance of eventual ‘manned’ interface;
n Dangerous goods should be packed in accordance with the IMDG Code.
