Coterena

What Coterena does

Coterena, S.L.U. is a privately-held Spanish naval and industrial mechanical services company founded in 1990 and headquartered at the Bouzas repair docks in Vigo, Galicia, with a secondary production facility in O Porriño. The company supplies, installs, repairs, and services spare parts and mechanical equipment for ship operators, shipyards, power generation plants, cogeneration facilities, transformer industry, railway transport, and heavy machinery customers. Its core technology is the proprietary ARGOS modular monitoring platform—a real-time ship navigation and propulsion monitoring system with modules for main engine consumption, auxiliary engine parameters, freezing chambers, bunkering, and environmental indicators (EEOI, SEEMP, SNV) used for fuel efficiency optimization and regulatory compliance. Supporting ARGOS, Coterena manufactures precision instruments such as the COT02 torquemeter and delivers laser alignment, JackLoad testing, vibration analysis, noise analysis, and industrial videoscopy services through its in-house Technical Office and dedicated Monitoring and Analysis (T+i) department.

The company makes money through professional services (repair, installation and commissioning, maintenance, and dynamic/static/environmental analysis), hardware sales of the ARGOS system and COT02 torquemeter, and e-commerce spare parts distribution via the Coterena Shop online platform, supplemented by reconditioned equipment sales under the Coterena brand. Distribution combines direct field sales at its two workshop facilities with an Official Service and Official Distributor partner network covering OEM/OES brands, plus regional agent and collaborating workshop partners such as BMA Re Ship Management. Coterena participates in industry events including the Navalia international naval trade show, maintains a trilingual (Spanish/English/French) web presence, and holds ISO 9001, ISO 14001, ISO 45001, and ISO 27001 certifications alongside GDPR compliance. The business is organized as a single-member limited liability company with 51-100 employees, appears bootstrapped with no disclosed external funding, and serves both local Galicia and international naval and industrial clients.

Core offering

Coterena supplies, installs, repairs, and services spare parts for the maritime and industrial sectors, delivering integrated mechanical repair, installation and commissioning, and preventive/predictive maintenance for engines, transmissions, thrusters, deck machinery, rudders, and auxiliary machinery. The company operates a proprietary ARGOS real-time monitoring platform for vessel propulsion efficiency and environmental compliance, sells OEM/OES and reconditioned spare parts through its Coterena Shop online store, and provides specialized dynamic and static analysis (laser alignment, JackLoad testing, videoscopy, vibration, noise, NOx/CO2 measurement).

Product overview

Coterena offers a portfolio of naval and industrial mechanical services built around its core ARGOS monitoring platform. The ARGOS system is a modular real-time navigation monitoring solution consisting of a Main Module (recording and visualization), a Main Engine Module (propulsion consumption and power), an Auxiliary Engine Module (generator monitoring), and optional modules (temperature, bunkering, environmental indicators). Supporting the ARGOS platform, Coterena provides a comprehensive suite of services including repair, installation and commissioning, maintenance, and spare parts through both direct service delivery and its Coterena Shop online store. Additional analytical services include dynamic analysis (power measurement, vibration, noise, videoscopy), static analysis (laser alignment, JackLoad testing), and environmental/energy efficiency consulting. The company also manufactures the COT02 torquemeter for precise shaft power measurement.

Scale indicators3 records

Recent moves5 records

Expansion highlights4 records

Broad incumbents

• Caterpillar Marine Power: Caterpillar Marine sells and services marine propulsion and generator sets through a dealer/service network, overlapping with Coterena's repair, installation and spare parts activities around engines, generators and gearboxes.
• Kongsberg Maritime: Kongsberg Maritime supplies integrated ship navigation, automation and remote monitoring systems. Overlap with Coterena's ARGOS monitoring/recording platform and ship efficiency services, but as a much larger full-stack vendor.
• MAN Energy Solutions (MAN PrimeServ): MAN PrimeServ provides OEM-backed marine engine repair, retrofitting and digital monitoring services globally. Comparable to Coterena's marine engine repair, installation and commissioning lines and to ARGOS-style performance monitoring, though at vastly larger scale.
• Wärtsilä Services Iberia: Wärtsilä operates a global marine service network for engine maintenance, monitoring and lifecycle support. Comparable to Coterena because both supply propulsion and auxiliary engine MRO plus digital condition monitoring to commercial shipowners, but Wärtsilä is far broader in scope and geography.
• TTS Marine (TTS-NMF): TTS supplies marine and offshore cargo handling, deck machinery and lifecycle services. Comparable to Coterena's deck machinery and auxiliary equipment repair lines, though at much larger scale.

Regional players

• BMA Re Ship Management: BMA Re is a listed Official Service partner of Coterena that distributes ship management and related services. Comparable because it routes demand for Coterena-style MRO into shipowner fleets in select markets, and is economically aligned with Coterena via the partnership.
• Industria de Turbo Propulsores (ITP) Aero / Marine services peers: ITP and adjacent Basque/Spanish industrial services firms serve propulsion and rotating equipment markets in Spain and southern Europe. Comparable as a regional industrial MRO and monitoring peer with overlapping naval and industrial customer base.

Direct peers

• Metalships & Docks (Hijos de J. Barreras): Metalships & Docks runs the Vigo-based Barreras shipyard focused on newbuilds and ship repair. Direct peer to Coterena in the Vigo marine cluster, competing for the same regional repair and refit demand.
• Zamakona Yards: Zamakona is a Spanish shipyard group with ship repair, conversions and offshore construction capacity. Direct peer to Coterena in Spanish-based ship repair and refit, especially in offshore and industrial marine segments.
• Navantia Shipyards: Navantia operates Spanish naval and commercial shipbuilding plus repair services. Direct peer because both perform mechanical MRO on propulsion, auxiliary and hull systems for shipowners operating in Iberian and European waters.
