Inventory of Hazardous Materials


Onboard health and safety is coming under increased scrutiny from national, European and global laws and regulations :

  • Hong Kong Convention, approved by the IMO in 2009

  • IMO RESOLUTION MEPC.269(68) (adopted on 15 May 2015 and as may be revised) combinated to MEPC.222 (64) and MEPC.223 (64).

  • EU Regulations No 1257/2013 & No1013/2006 and Directive 2009/16/EC

The purpose


The IHM is a lifelong inventory of a vessel’s materials to promote safer, provide better hazard management and more environmentally sound recycling of ships.IHM is already seen as a best practice standard. The benefi ts of the inventory are widely acknowledged within the industry worldwide


Identifies all hazardous substances, products or materials on board : asbestos, mercury, chromium-6, polychlorinated biphenyls (PCB’s) or leaded paint.


Provides access to harbours that require this inventory.


Contributes to a safe workplace for your employees and people working on board.


Provides tools to take further actions, promoting the safety on board.


Gives your company or shipowner a strong position in liability issues.


At the end of life, the ship can be dismantled with low risks for people and the environment.

Do I have to carry out an IHM ?

  • IAll EU-fl agged types of vessels of 500 GT and over must have an IHM on board

  • Vessels from non-EU countries will be required to carry an IHM when calling at EU-ports

  • EU-fl agged vessels must be dismantled in an approved ship recycling facility

  • New built EU-fl agged vessels must have an IHM on board with a Statement of Compliance

The responsibility of the IHM lies indirectly with the ship or fleet owner, or directly with the ships technical management.​

The purpose

In practice

In practice

There are different IHM-approaches concerning the life stages of an existing ship :

  • A first desk research and a visual inspection carried out during IHM Part I : It provides a solid foundation for a Part II research

  • After this first step, and preparing a Visual Sampling and Checking Plan, an approved Expert will collect samples of many kinds of materials during an onboard survey in order to make them analyzed in a certified laboratory

  • The report is prepared by the approved expert to be available on board


The IHM should be re-inspected annually to ensure its relevance and a full re-survey of the vessel carried out every five years.

The IHM report will be further expanded, meaning the report eventually covers the entire life cycle of a vessel. You will have opportunity to update when :

When the vessel has reached the end of its economic life, a final investigation is carried out. The final report represents a reliable source of information for the ship recycling plan :

  • Part II : a ship destined to be recycled shall minimize the amount of cargo residues, fuel oil and wastes remaining on board. A research of the wastes listed in part II of the Inventory shall be carried out

  • Part III : the fi nal survey, taking into account each item listed in part III, with quantity and location of the stores. This step gives insight into all regular consumable goods already on board. The ship can then be dismantled safely
