IMO (International Maritime Organization)

Definition: IMO — International Maritime Organization — the United Nations agency that develops maritime safety, environmental protection and international standards. Headquartered in London. The primary source of global shipping regulation.

Main conventions

  • SOLAS — Safety of Life at Sea (vessel safety)
  • MARPOL — Marine Pollution (prevention)
  • STCW — Standards of Training, Certification and Watchkeeping (crew training)
  • MLC — Maritime Labour Convention (seafarer rights)
  • ISM Code — International Safety Management (operational safety)

IMO number

Every commercial vessel gets a unique 7-digit identifier (e.g. IMO 9876543). It stays the same even if owner, flag or name changes. Used in insurance + contract + registry processes.

IMO environmental targets

  • IMO 2020 — Sulphur limit (0.5% in marine fuel)
  • IMO 2030 — 40% carbon emission reduction
  • IMO 2050 — 70% carbon emission reduction

These targets matter for financing:

  • Older + non-compliant vessels fall into the scrappable category
  • New-technology vessels qualify for green finance
  • Banks look at IMO compliance
