9.1.1 International certificates

  9.1.1.1 The following international certificates may be relevant:

  • .1 International Oil Pollution Prevention Certificate (IOPP Certificate);

  • .2 International Pollution Prevention Certificate for the Carriage of Noxious Liquid Substances in Bulk (NLS Certificate);

  • .3 International Certificate of Fitness for the Carriage of Liquefied Gases in Bulk, or the Certificate of Fitness for the Carriage of Liquefied Gases in Bulk, whichever is appropriate;

  • .4 International Certificate of Fitness for the Carriage of Dangerous Chemicals in Bulk, or the Certificate of Fitness for the Carriage of Dangerous Chemicals in Bulk, whichever is appropriate; and

  • .5 Certificate of Fitness issued under the Provisions of the Guidelines for the Transport and Handling of Limited Amounts of Hazardous and Noxious Liquid Substances in Bulk on Offshore Support Vessels (LHNS Certificate).

  9.1.1.2 The port authority should, in accordance with the legal requirements of the regulatory authority , be able to prohibit:

  • .1 the entry into the port area of a ship carrying bulk oil, unless the master is in possession of a valid IOPP Certificate, supplemented with form B – Record of Construction and Equipment for Oil Tankers;

  • .2 the entry into the port area of a ship carrying liquid bulk dangerous cargoes to which the Codes for the Construction and Equipment of Ships Carrying Dangerous Chemicals or Liquefied Gases in Bulk are applicable, unless the master is in possession of a valid Certificate of Fitness ;

  • .3 the entry into the port area of a ship carrying liquid bulk dangerous cargoes to which the Codes for the Construction and Equipment of Ships Carrying Dangerous Chemicals or Liquefied Gases in Bulk are not applicable, unless the master is in possession of a valid NLS Certificate; and

  • .4 the loading and unloading of liquid bulk dangerous cargoes into or from ships referred to in 9.1.1.2.1 to 9.1.1.2.3 unless the master is in possession of a valid IOPP Certificate, Certificate of Fitness or NLS Certificate, as appropriate, for the ship and those dangerous cargoes .

  9.1.1.3 The regulatory authority should establish appropriate arrangements for the inspection of a ship , to ensure that it complies with any certificate, referred to in 9.1.1.1, where there is reason to believe that the ship may not comply.

9.1.2 Vapour emission control

  9.1.2.1 Subject to the requirements of the regulatory authority , the port authority may require that whenever certain liquid bulk dangerous cargoes are handled, suitable and safe measures are taken to prevent or control the emission of vapour into the atmosphere. Attention is drawn to IMO Circular MSC/Circ.585 on Standards for Vapour Emission Control Systems.

9.1.2 This is a complex matter and under continuous development by experts. Local environmental conditions and legal requirements should be taken into account in deciding whether to require any vapour-return line or vapour-disposal system. If such a system should be required, due attention should be given to avoiding additional hazards.

9.1.3 Information for operational and emergency purposes

  9.1.3.1 The master of a ship and the berth operator , within their respective areas of responsibility, should have immediately available the following information with respect to each dangerous cargo transported or handled :

  • .1 the product name of the cargo, the UN number (where available) and a description of the relevant physical and chemical properties (including reactivity) necessary for the safe containment and handling of the cargo;

  • .2 procedures for the cargo transfer, slop transfer, gas-freeing, inerting, ballasting, de-ballasting and tank cleaning;

  • .3 special equipment needed for the safe handling of a particular cargo; and

  • .4 appropriate emergency response procedures, including the:

    – action to be taken in the event of a spillage or leak;

    – counter-measures against accidental contact; and

    – fire-fighting procedures and the suitable fire-fighting media.
