IHM Maintenance

Completing and verifying an initial IHM, is only the beginning of being compliant. IHM is a living document. Maintaining it up-to-date throughout vessel’s life-cycle is a key according to both the Hong Kong International Convention for the Safe and Environmentally Sound Recycling of Ships and the EU SRR. Maintaining compliance for the entire service life of a vessel requires action. Any change on board must be identified and assessed and an update to IHM is required every time something changes. Also, HSQE issues onboard, related to IHM, requires active and constant monitoring. A maintained Inventory of Hazardous Materials (IHM) is indispensable for minimizing health risks to a vessel’s crew and to meeting mooring requirements.
An IHM covers the entire life cycle of the vessel, from construction, throughout its active service life, until dismantling. Our IHM Maintenance service simplifies the update process. Utilizing data from PMS (Planned Maintenance System) and Purchasing (Stores, Spares, Consumables etc.) modules, IHM-sensitive items are identified, related data is collected and assessed, periodical reports are created and IHM is efficiently maintained. Once the IHM report is created, it’s logged to our database where it is being updated.
