EMENASA

What EMENASA does

EMENASA (Electromecánica Naval e Industrial, S.A.) is a privately held Spanish electrical engineering company founded in 1956 in Vigo, Spain, specializing in turnkey electrical installations, switchboard and console manufacturing, and electric-machine repair for the global marine market. Its product portfolio comprises custom power generation and distribution switchboards meeting major Classification Society standards (with integrated PMS, PLCs, and PCs), bespoke bridge and Engine Control Room (ECR) consoles developed in 3D engineering workflows, and a repair/maintenance service line covering motors and generators up to 110 MW and 15 kV including VPI impregnation and balancing. The company serves four principal segments — shipyards and newbuilding vessels (its primary vertical), vessel owners and operators, industrial power generation (wind, hydroelectric, cogeneration), and naval/government clients — through a direct enterprise field-sales motion and worldwide deployment of field-service engineers. Revenue mechanics are project-based and custom-quoted across three streams: turnkey installations (one-time project revenue), switchboard/console manufacturing (hardware sales), and maintenance/repair services (professional services); no public pricing exists.

EMENASA is the flagship entity of Grupo Emenasa, a corporate group of 12 independent companies that collectively employs ~600 staff (including ~90 engineers), operates across 30 countries, and reports turnover above €200 million; the group's broader scope spans engineering (PDI Beiramar/MainSolutions, HGA, Vicus DT), industrial automation and robotics manufacturing (Enaradio, EMENASA EIA, MainSolutions), maintenance/repair (Mecanasa), and distribution/after-sales (Núñez Vigo, Baliño, Fundivisa, Progener, Garcia Costas). EMENASA itself occupies a 3,000 m2 industrial warehouse in Vigo divided between an electric-machine workshop and a switchboard/console manufacturing area; the firm tripled its footprint in 2015 when it added EIA to the group and inaugurated a new production warehouse. It is certified to ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 (Bureau Veritas) and holds OEM after-sales authorizations for MARELLI, AvK STAMFORD, and MARELEC.

In December 2025 the shareholders approved a partial corporate split (escisión parcial) under Royal Decree-Law 5/2023, transferring part of the company's patrimony to a newly created beneficiary entity, Grupo Industrial Emenasa S.L., while preserving the existing shareholder base — a defensive restructuring that redefines EMENASA's perimeter going forward but does not change operating status. The company's go-to-market relies on direct B2B enterprise sales backed by flagship maritime trade-show participation (Nor-Shipping, SMM Hamburg, Navalia) rather than digital or channel-partner distribution.
