Vessel-type-specific Inventory of Hazardous Materials guidance for the global container fleet (from feeders to Ultra-Large Container Vessels). Continuous IHM Part I, II & III maintenance aligned with HKC, EU SRR and MEPC.405(83) — powered by Varuna Sentinels’ VSIMS platform.
Below are the regulatory and operational pillars every container ship operator should track in 2026 — alongside the universal HKC and EU SRR baselines.
Container ships above 500 GT are in full HKC scope from 26 June 2025.
Refrigerated cargo (reefer) plug systems use HFC/HFO refrigerants requiring detailed IHM Part I documentation.
Fixed CO2 fire suppression systems and PFAS-containing engine-room foams are priority IHM scope items.
Major container lines (Hapag-Lloyd, Maersk, MSC, CMA CGM) are now publicly aligning fleet IHM with CSRD/ESG reporting.
Container ship retrofits to dual-fuel (LNG, methanol) trigger material IHM Part I updates for fuel system insulation, gaskets and seals.
Container ship IHM Part I has unique scope around reefer plug systems (HFC/HFO refrigerants), fixed CO2/foam fire-suppression in engine rooms, and dual-fuel retrofit fuel-system materials. Hapag-Lloyd is among the major liner companies running fleet-wide IHM maintenance via Varuna Sentinels VSIMS.
Our cloud-based VSIMS platform delivers continuous IHM Part I maintenance, automated MEPC.405(83)-compliant Material Declarations, vessel-type-specific sampling templates, IHM Part II & III preparation for end-of-life events, and audit-ready evidence packs for Port State Control inspections.
