AEGIR-Marine

What AEGIR-Marine does

AEGIR-Marine BV is a Netherlands-based, privately held maritime services company founded in 2000 by Ruud Muis and Hans Dekker that operates as an OEM-independent specialist in stern tube seals and ship propulsion systems. The company provides overhauls, retrofits, seal-bonding repairs, underwater repairs, thruster and propeller servicing, stabilizer maintenance, and propulsion-control support to commercial vessel owners, ship managers, shipyards, and operators across more than 70 countries. Its proprietary PRIME product line, manufactured in-house since 2004 using a unique Viton compound, covers stern tube seals (155-1180mm), propulsion spare parts, retrofit systems, and protection systems including the AEGIR Protection System (APS). All PRIME spares are kept in stock and can be shipped within the hour, with manufacturing exclusively in Western Europe.

The business combines a professional services model, with field service engineers dispatched from 13 global offices (Netherlands, Singapore, Dubai, USA, China, Panama, Namibia, Greece, Türkiye, Estonia, Brazil, Australia), with hardware sales of PRIME parts under standard terms (net 30 days, 1.5% monthly interest on overdue accounts, Ex Works delivery, 12-18 month warranty). Specialized capabilities include an in-house R&D laboratory for stern-tube-seal lifespan prediction, 3D scanning reverse engineering at 0.025mm accuracy for obsolete parts, the Sealdock underwater habitat system co-developed with UPE, and the PACMan submerged hydraulic press (triple class-approved in Q1 2024 by Lloyd's Register, NKK, and ABS) for underwater propeller cold-straightening developed with UPE and Plug & De Boer.

The company is controlled by founder Ruud Muis (now Chairman and Owner) under a one-tier board structure, with approximately 40% of permanent employees participating in an employee share ownership program in its fourth year. A satellite company, ATLA Propulsion Controls (majority-owned, run by Muis's children Thom and Femke), extends the offering into propulsion-control electronics. AEGIR-Marine is the world's first certified maritime B Corp, holds ISO 9001/14001/45001 certification from DNV (June 2024) covering all offices, and has received consecutive World-class Workplace accreditation from Effectory since 2022. As of 2025, the company employs around 240 professionals of 29 nationalities and is led by incoming CEO Peter Ritskes (effective July 1, 2025), succeeding Jaap de Lange.

Scale indicators8 records

Recent moves11 records

Expansion highlights7 records

Broad incumbents

• Wärtsilä: Wärtsilä is one of the largest marine engine and propulsion system OEMs with a global service network covering lifecycle services, parts, and digital solutions. Although a propulsion equipment manufacturer first, its service portfolio directly competes with AEGIR-Marine for service contracts on installed marine propulsion systems.
• Brunvoll: Brunvoll is a Norwegian thruster and propulsion manufacturer with an established service network for marine operators. It is relevant as both an OEM whose installed base AEGIR-Marine services and as a peer in the global marine propulsion aftermarket.
• Kongsberg Maritime: Kongsberg Maritime supplies propulsion, thruster, and control systems for commercial vessels and runs a global aftermarket service network. Its thruster control and propulsion controls product line directly overlaps AEGIR-Marine's propulsion controls service and ATLA Propulsion Controls expansion.
• Schottel: Schottel is a German manufacturer of marine propulsion systems including controllable pitch propellers, azimuth thrusters, and rudder propellers. Its service network for installed thruster and propeller systems competes with AEGIR-Marine's propulsion service line.
• SKF Marine: SKF supplies bearings, seals, and condition monitoring for marine propulsion applications including stern tube and thruster systems. Its marine aftermarket business overlaps directly with AEGIR-Marine's parts and service proposition, though SKF operates at vastly greater scale and breadth.
• Wabtec (Marine): Through legacy GE Transportation and other marine assets, Wabtec provides propulsion and control technology for commercial vessels with a global service footprint. It represents a broad-incumbent competitor in marine propulsion controls and aftermarket services.

Others

• Damen Shipyards: Damen is a Dutch shipyard group and a current AEGIR-Marine customer (bow thruster overhauls at Damen shipyard). It is comparable as a downstream shipyard customer and as a Dutch maritime industrial peer, but Damen builds vessels rather than providing aftermarket services directly.
• Vroon: Vroon is a Dutch-based shipping company with extensive in-house technical management of its vessels. It is comparable as a customer-side peer and Dutch maritime employer, though Vroon operates ships rather than competing in the service provider market.

Direct peers

• Goltens Worldwide: Goltens is a global independent marine service and repair company with a comparable OEM-independent model, offering in-situ machining, crankshaft services, and engine room repairs across a similar geographic footprint to AEGIR-Marine. They directly compete for the same ship-owner service budget and share the OEM-independent positioning.
• Trelleborg Marine & Infrastructure: Trelleborg supplies marine sealing solutions including stern tube seals and bearings to shipbuilders and operators globally, and is a direct competitor to AEGIR-Marine's PRIME seal product line. Its broader polymer-engineering portfolio makes it a more diversified peer in the same product category.
