Hazardous materials specialist Lucion has issued a stern warning to the global maritime community: the Inventory of Hazardous Materials (IHM) is not a 'one-time' compliance milestone. This alert follows a series of recent vessel detentions that have exposed significant gaps in how technical managers maintain their hazardous material documentation, particularly for ships calling at UK and EU ports.
In recent weeks, Port State Control inspectors have detained two Marshall Islands-flagged vessels after identifying that their IHM Statements of Compliance were either expired or fundamentally inaccurate. The Republic of the Marshall Islands Maritime Administrator has since issued Marine Safety Advisory No. 04-26, mandating that operators urgently verify the integrity of their documentation. Under the EU Ship Recycling Regulation (EU SRR 1257/2013), any vessel calling at EU or UK ports—regardless of its flag—must maintain a valid, up-to-date IHM record.
The core of the problem lies in a widespread misconception that IHM compliance ends once the initial certificate is issued. Kevan O’Neill, Principal Consultant at Lucion, emphasizes that the inventory is a 'live document.' Routine activities, such as structural modifications, retrofits, or even minor equipment replacements, require an immediate update to the IHM. Failure to document these changes leads to a disconnect between the official paperwork and the actual physical state of the vessel, which inspectors are now rigorously auditing.
During current inspections, authorities are moving beyond checking for the mere existence of a certificate. They are cross-referencing IHM documents with shipyard invoices, equipment purchase orders, and recent refit records. Discrepancies found during these deep dives are resulting in immediate detentions, which carry heavy financial penalties and severe operational disruptions for shipowners relying on tight, just-in-time schedules.
Beyond the operational risk, the reputational impact on owners and charterers is significant. Insurers and commercial partners are increasingly factoring regulatory reliability into their decision-making processes. Lucion warns that as inspections continue to tighten, the 'reactive correction' approach—attempting to fix documentation only when a port inspection is imminent—will no longer be a viable strategy.
For operators, the path forward is proactive maintenance. This involves embedding IHM reviews into the daily technical management lifecycle of every ship. By ensuring that hazardous material data remains accurate throughout the vessel's entire operational life, owners can mitigate the risk of detention and demonstrate a commitment to both environmental safety and regulatory excellence.
