Navalco

What Navalco does

Navalco (legal name: NAVALCO SERVICIOS DE REPARACIÓN Y MANTENIMIENTO DE MOTORES MARINOS Y COGENERACIÓN, S.L.) is a privately held Spanish company founded in 2009 and headquartered in Arteixo, A Coruña. The company specializes in the supply of spare parts and the repair, reconditioning, and maintenance of medium-speed marine diesel and gas engines, primarily Wärtsilä-Vasa (series 20/22/32/46), Deutz (BWM 816/528/628 and 620/640/645), and MAK (series 20/25/32/43), serving both ship owners/operators and stationary power generation and cogeneration plants. Its product portfolio spans injection components (L'Orange, Woodward, Bosch, OMC), bearings, cylinder heads, pistons and liners, instrumentation, filters, MANN+HUMMEL centrifuges, GALI air starters, and Dr. E. Horn oil mist detectors, complemented by H+H Engineering SCR systems for IMO TIER III NOx compliance.

The company's technical infrastructure is built around a 7,000+ m² workshop and warehouse at Polígono de Sabón (expanded in 2019), equipped with ultrasonic cleaning tanks, Chris Marine honing equipment up to 700mm, Schenck dynamic balancing up to 6 tonnes, ABB/Napier turbocharger overhaul, hydraulic testing, and resistive load bank testing up to 750 kVA. Navalco also operates an international on-board mobile workshop for in-situ reconditioning at customer vessels or facilities worldwide. Service channels include direct sales-led engagement (phone/email 24/7/365), participation in the Navalia international naval industry fair, and a quote-based pricing model for both parts and services. The company holds exclusive representative status for GALI air starters (Spain), Dr. E. Horn (Spain, Portugal, Caribbean), and H+H Engineering, and is a certified MANN+HUMMEL Centrifuge Specialist Installer.

Navalco monetizes through four streams: hardware sales of spare parts, in-house workshop repair and overhaul services, international on-board mobile technical services, and engine control/emission retrofitting (including WECS 2000 for Wärtsilä engines and SCR systems for IMO TIER III). It is certified to ISO 9001, ISO 14001, and ISO 45001 (DNV) and received European Regional Development Fund support in 2021 under the XPANDE DIGITAL program for international digital positioning. The firm operates with 11-50 employees, serves named customers across cruise (Silja Serenade), LNG (FSRU Exquisite), fishing (Tersan NB1085 Atlantic), and NGO maritime rescue (Proactive Open Arms) segments, and is privately held with no disclosed external institutional ownership.

Direct peers

• Kongsberg Maritime: Kongsberg Maritime provides engine automation, control systems, and digital monitoring for marine engines, overlapping with Navalco's engine control retrofitting service (e.g., WECS 2000 replacements) and engine parameter monitoring offerings.
• HEINZMANN: HEINZMANN develops and supplies engine management, control, and monitoring systems for medium- and high-speed diesel and gas engines. Its products overlap with Navalco's engine control retrofitting and monitoring services and compete for similar retrofit budgets.
• Rolls-Royce (Bergen Engines): Bergen Engines (Rolls-Royce) produces medium-speed gas and diesel engines for marine and power plant use, a brand explicitly mentioned in Navalco's cylinder head reconditioning capability. Bergen competes with Wärtsilä and Deutz and offers its own aftermarket service network.
• Anglo Belgian Corporation (ABC): ABC manufactures medium-speed diesel and dual-fuel engines for marine and power generation applications and provides aftermarket services. It competes with the Wärtsilä/Deutz/MAK engine families that Navalco services and supplies parts for.

Broad incumbents

• MAN Energy Solutions: MAN Energy Solutions manufactures medium- and large-bore marine engines and operates a worldwide service network covering spare parts, retrofits, and emission upgrades. It overlaps with Navalco in the marine engine MRO and retrofit space, including IMO TIER III solutions.
• Wärtsilä Services: Wärtsilä operates a global service network for its own marine engines, including the Vasa 20/22/32/46 series that form a core part of Navalco's spares catalogue. It is the OEM against which Navalco competes as an independent alternative for parts and overhaul.
• Alfa Laval: Alfa Laval supplies marine separators, heat exchangers, and related equipment and services. Navalco already partners with Alfa Laval by overhauling its separators as part of Wärtsilä engine packages, making Alfa Laval a natural adjacent competitor in marine equipment MRO.
• Caterpillar Marine Power: Caterpillar provides marine engine sales, parts, and service globally for its propulsion and auxiliary engines. It is comparable to Navalco in offering parts supply plus aftermarket service for marine diesel installations.
• ABB Marine & Ports: ABB supplies turbochargers, propulsion controls, and digital services for marine vessels. ABB turbochargers are explicitly overhauled by Navalco (ABB and Napier), positioning ABB as both a partner and an adjacent competitor in marine service offerings.

Emerging players

• H+H Engineering and Service GmbH: H+H Engineering designs and installs SCR systems for marine and stationary applications. Navalco is H+H's representative for Iberia, so H+H is both partner and an emerging competitor in the emission retrofit space that Navalco is helping to scale.
