Complete Inventory of Hazardous Materials maintenance and Hong Kong Convention guidance for the third-largest open registry (~5,000 vessels, ~190M GT). Continuous IHM Part I, II & III updates aligned with HKC, EU SRR and MEPC.405(83) — powered by Varuna Sentinels’ VSIMS platform.
Marshall Islands ratified the Hong Kong Convention. Below are the regulatory pillars every Marshall Islands-flagged ship operator should track in 2026.
Third-largest open registry by tonnage; one of the fastest-growing flags.
Hong Kong Convention party — full IHM compliance required from 26 June 2025.
Recent Port State Control detentions of Marshall Islands-flagged vessels have highlighted IHM compliance as a top enforcement priority.
IRI Marine Notice 2-011-50 covers IHM and ship recycling responsibilities.
Continuous IHM maintenance is the documented expectation of the administrator.
IRI publishes formal Marine Notices on IHM development and maintenance obligations. PSC detention case studies (notably 2025 incidents) demonstrate that incomplete or stale IHM Part I is sufficient grounds for vessel detention under HKC.
Our cloud-based VSIMS platform delivers continuous IHM Part I maintenance, automated MEPC.405(83)-compliant Material Declarations, IHM Part II & III preparation for end-of-life events, and audit-ready evidence packs for Port State Control inspections. We coordinate with your Recognised Organisation, classification society and recycling yard from the first survey to the final IRfRC.
