IHM maintenance service hero banner — OSM Thome Inventory of Hazardous Materials compliance

IHM Maintenance Service

With the EU Regulative SRR 1257/2013 implemented on January 1, 2021, all vessels calling a port in the EU must have an IHM certificate onboard (Inventory of Hazardous Materials).
In addition to the above, IMO Guidelines MEPC. 269 (68) also state that the shipowner is responsible for maintaining the IHM inventory list during the vessels’ lifetime.

Ship owners must implement specific measures to ensure conformity with Part I of the inventory (MEPC 5.2). For this reason, most shipowners and management companies have decided to outsource this function to recognize hazardous materials companies.
OSM Thome has in-house competence in IHM maintenance and, hence can offer the same level of service as a third-party company to all customers (existing under our technical management or not) for their vessels.

IHM MAINTENANCE SERVICE

What shipowners must do to ensure IHM maintenance compliance

Ship-owners must implement the following measures to ensure conformity of part I of the inventory (MEPC 5.2):

  • Designate a person as responsible for maintaining and updating the inventory
  • The designated person should establish and supervise a system to ensure
    necessary updating of the inventory in the event of a new installation onboard
  • Maintain the inventory including dates of changes or new deleted entries
  • Provide related documents as required for the survey or the sale of the ship
