In 2013, EU has introduced EU Ship Recycling Regulation (SRR) 1257/2013, according to which:
All EU-ships heading sent for recycling since December 2016 are obliged to have a verified IHM with competent Certificate onboard as well while they have to be recycled in an EU-approved Ship Recycling Facility.
According to SRR, shipowners are responsible for compilation & maintenance of Part I of the IHM during the lifetime of the ship. Part I of the IHM should belong to the ship and the continuity and conformity of the information it contains should be confirmed, especially if the flag, owner or operator of the ship changes.
Practically, after December 31st 2020, this means that:
In general, by the end of 2020, all ships weighing over 500GT entering EU ports will be required to carry an IHM.
