The IMO adopted the Hong Kong International Convention for the Safe and Environmentally Sound Recycling of Ships in 2009. Its purpose is to ensure that ships, when being recycled after reaching the end of their operational lives, do not pose any unnecessary risk to the environment or human health and safety. In addition, the convention seeks to clinch the proper management of hazardous materials on board ships.
The convention addresses all the issues surrounding ship recycling, including the fact that ships sold for scrap may contain environmentally hazardous substances such as asbestos, heavy metals, hydrocarbons, ozone depleting materials and others. It also addresses concerns about working conditions in many of the world's ship recycling facilities.
Regulations in the new convention covers: the design, construction, operation and preparation of ships to facilitate a safe and environmentally sound recycling process, without compromising operational efficiency and safety of the ships built, the operation of ship recycling facilities in a safe and environmentally sound manner, and the establishment of an appropriate enforcement mechanism for ship recycling incorporating certification and reporting requirements.
Ships to be sent for recycling will be required to carry an inventory of hazardous materials, which will be specific to each ship. An appendix to the convention provides a list of hazardous materials, the installation or use of which is prohibited in shipyards, ship repair yards, and ships of parties to the convention. Ships will be required to have an initial survey to verify the inventory of hazardous materials, renewal surveys during the lifespan of the ship, and a final survey prior to the recycling process.
Hazardous materials can impair our life and the environment without proper management. They must be identified, managed and recycled over the entire span of the ship’s lifecycle. While the convention still relies on the concept of a ‘Green Passport’, which remains central to most, if not all, operations, the term itself is no longer used. The “Green Passport” is now known as the ‘Inventory of Hazardous Materials’ (IHM), though its purpose remains identical. The IHM still covers the entire lifespan of the ship, from the construction and operation to the preparation for scrapping at the end of the ship’s lifetime.
CTI, as an international leader in IHM surveys, can reliably check the ship’s compliance with the convention, and can guide shipyards in meeting the requirements for class issuing, the endorsement of an international certificate regarding the IHM, and the issuance of an International Ready for Recycling certificate.
The objective of the IHM is to provide information on the hazardous materials present on-board the ship in order to protect the health and safety of the workers and to prevent any potential environmental pollution at ship recycling facilities. This information will be used by the ship recycling facilities to decide how to manage the materials identified in the IHM.
For new ships, Part I (Table A &Table B) of the IHM should be developed at the design and construction stage.
Since 31 Dec. 2018, all ships flying the flag of a Member State have been subjected to a survey regime and have had to carry on-board a ship-specific ‘Inventory Certificate’ issued by the administration or a RO authorised by it and supplemented by Part I of the IHM, which has been attached below for your reference:
|A2||Polychlorinated biphenyls (PCBs)||50mg/kg|
|A3||Ozone Depleting Substances||no threshold level|
|A4||Anti-fouling systems containing organizing compounds as a biocide||2500mg total tin/kg|
|A5||Perfluorooctane sulfonic acid ( PFOS)||10mg/kg|
|B1||Cadmium and Cadmium Compounds||100mg/kg|
|B2||Hexavalent Chromium and Hexavalent Chromium Compounds||1000mg/kg|
|B3||Lead and Lead Compounds||1000mg/kg|
|B4||Mercury and Mercury Compounds||1000mg/kg|
|B5||Polybrominated Biphenyl ( PBBs)||50mg/kg|
|B6||Polybrominated Diphenyl Ethers ( PBDEs)||1000mg/kg|
|B7||Polychlorinated Naphthalenes ( more than 3 chlorine atoms )||50mg/kg|
|B8||Radioactive Substances||No threshold value|
|B9||Certain Shortchain Chlorinated Paraffins ( Alkanes, C10 – C13 , chloro)||1%|
|B10||Brominated Flame Retardant ( HBCDD)||100mg/kg|
CTI, as the international leader for IHM surveys, can provide the IHM survey to ensure that ships comply with the Convention, and guide shipyards to meet the requirements for Class issuing and endorsing an International Certificate on IHM and issuing an International Ready for Recycling Certificate.
