meok-imo-marpol-marine-mcp

IMO MARPOL + marine fuel + container ship compliance MCP. MARPOL Annex VI, EU ETS maritime, CII, EEXI, IMDG, bunker fuel, ballast water, Port State Control inspection prep. By MEOK AI Labs.

Why this exists

MEOK started with road haulage. Maritime is the next vertical — short-sea operators (RoRo car carriers, Channel freight), container shipping, and the marine fuel cliff for net-zero. 2026 is the year the bills come due: EU ETS maritime is biting, CII/EEXI ratings are public, and the 2030 GHG step-change is closer than most fleet managers think.

Real cliffs this MCP exists to help operators clear:

MARPOL Annex VI 0.5% sulfur cap (global, Jan 2020) + 0.1% in ECAs (North Sea, Baltic, North America). Fines up to USD 250k + vessel detention by Port State Control.
EU ETS maritime (Jan 2024) — 50% of intra-EU + 100% of intra-EU voyages carbon-priced. 2026 ramp: 70% of allowances surrendered (vs 40% in 2024).
CII annual rating (since Jan 2023) — A/B/C/D/E. Three consecutive D or one E = corrective action plan required.
IMDG Code — Class 9 lithium batteries on container ships (Felicity Ace 2022, Fremantle Highway 2023 — 4,000+ vehicles lost combined).
IMO Ballast Water Management Convention (2017) — D-2 standard rollout completing 2024-2025.
Port State Control detention rates: Paris MoU 3.4% (2024), Tokyo MoU 3.1%. Each detention = 24-72h vessel delay = USD 30-100k.
