Koedood Marine Group

What Koedood Marine Group does

Koedood Marine Group is a Netherlands-based marine propulsion and power solutions provider founded in 1961 and headquartered in Hendrik-Ido-Ambacht. Operating as a subsidiary of Germany's STORM-Group since 2021, the company supplies and services marine diesel and gas engines — Mitsubishi since 1978 and Bergen Engines since 2025 — alongside in-house developed aftertreatment systems. Its primary customers are European inland waterway operators, seagoing vessel owners, shipyards, and offshore platform operators across Benelux, Germany, France, Austria, and Switzerland. Koedood sells complete propulsion packages including engines, reverse gearboxes, generator sets, aftertreatment, and control systems, and operates Europe's largest Mitsubishi spare parts warehouse.

The company's proprietary KEES (Koedood Engine Emission System) aftertreatment platform, with more than 150 units in operation and 135+ Stage V engines sold, addresses EU Stage V and IMO Tier III emissions mandates. KEES Next Gen, integrating DPF and SCR into a single housing (40% more compact), is targeted for summer 2026 release. Koedood also runs active R&D programs in hydrogen internal combustion engines (H₂ICE) with Mitsubishi Engine and TNO, and in dual-fuel methanol retrofit kits with MTEE. The company maintains 18 dedicated service engineers providing 24/7 worldwide field service and overhaul, plus in-house R&D, engineering, and a metaalbewerkers/own-quay workshop enabling single-site project execution.

Revenue is generated through a mix of one-time equipment sales (new engines, KEES systems, spare parts) and recurring professional services (24/7 maintenance, repair, overhaul, re-engining projects). Distribution runs through direct field sales (Sales Manager Menno Bijnagte and named account managers) and exclusive OEM dealer relationships. The company is part of the STORM-Group distribution and service network, which includes affiliated brands ScanDiesel, Wulf Johannsen, and August Storm. Subsidiaries Hybrid Ship Propulsion (electric motors) and former subsidiary Emigreen (aftertreatment) extend the offering into hybrid and IMO Tier III seagoing solutions.
