In May 2009, the Hong Kong International Convention for the Safe and Environmentally Sound Recycling of Ships (Ship Recycling Convention) was formally adopted at a Diplomatic Conference in Hong Kong. The purpose of the Ship Recycling Convention is to prevent, reduce, minimise and, to the extent practicable, eliminate accidents, injuries and other adverse effects on human health and environment caused by ship recycling, and to enhance ship safety, protection of human health and the environment throughout a ship’s operating life (Article 1). Specific regulations for safe and environmentally sound recycling of ships are annexed to the new Convention. In order to allow for the effective implementation of the Convention, IMO has been focusing its effort in developing a set of guidelines covering aspects such as the development of the inventory of hazardous materials, development of ship recycling plan, authorisation of ship recycling facilities, and safe and environmentally sound ship recycling.

Central to the implementation scheme of the Convention is the development and maintenance of a document referred to as the Inventory of Hazardous Materials (IHM), which was previously known as the “Green Passport” (GP) in IMO Resolution A.962(23) now amended by the Ship Recycling Convention and the IHM development guidelines contained in IMO Resolution MEPC.269(68). The Inventory is ship-specific and covers the whole life of the ship, from construction, throughout the ship’s operating life to preparation for scrapping at the end of the ship’s useful life. The main differences between IHM and Green Passport are that IHM requires more detailed and reasonably accurate account of the listed hazard substances in the inventory booklet and sampling to be carried out for existing ships.

IHM Considerations: When, How and Why


The best time to develop the IHM is during the planning and construction phase of the project where there is virtually unrestricted access to supplier and technical information. During this phase, there is a tight focus on the project scope which results in the efficient production of the IHM.

The IHM can be developed for existing vessels however there are a few more issues to consider. If you are managing a fleet and most (if not all) of your vessels require IHM, there will be a significant impact on vessel availability and the necessary resources required to address IHM production. Each vessel will require an individual survey, likely a docking survey, to address the IHM requirements. Postponing the production of your IHM will likely result in increased risk, time and cost due to:
  • Collection of necessary data.
  • Assessment of collected data and correction of any exceptions.
  • Preparation of the required visual and sampling plan.
  • Onboard visual survey and collection of samples.
  • Final preparation of Part 1 of the Inventory.
  • Preparing test methods.
  • Producing the location diagram of hazardous materials onboard of the ship.
Recalling that an IHM is ship-specific, the requirements apply to each ship regardless of its lineage.

Even if your present project does not require an IHM, the best time to address IHM is now. The rush to comply with the requirement will certainly have a drain not only on classification but on local industry and your fleet personnel.

Information is plentiful and free. Please contact Marine Plant Systems and speak to one of our crew about your project. Let us give you the benefit of our experience so that you can make an informed decision regarding your IHM.
