Vessel-type-specific Inventory of Hazardous Materials guidance for the global offshore support fleet (AHTS, PSV, MPSV, OCV, accommodation 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 offshore support vessel operator should track in 2026 — alongside the universal HKC and EU SRR baselines.
OSVs above 500 GT are in full HKC scope from 26 June 2025.
Anchor-handling winches, crane systems and dynamic positioning components are key IHM scope items.
Recent SOLAS amendments tighten requirements on anchor-handling winch braking and emergency-release systems.
Offshore wind support vessels (CTVs, SOVs) face the same HKC threshold and a fast-growing fleet pipeline.
Life Cycle Assessment is increasingly material for offshore wind support tonnage given charterer ESG reporting.
OSV IHM Part I covers anchor-handling winches and braking systems, crane hydraulics, DP system components, deck cargo handling equipment, ROV/subsea launch systems and accommodation modules (for SOVs). New SOLAS developments on anchor-handling winches require updated IHM evidence for retrofit components.
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. We coordinate with your Recognised Organisation, classification society and recycling yard from the first survey to the final IRfRC.
