What Almarin does

Almarin (ALMARIN EQUIPOS Y SERVICIOS PORTUARIOS, SL) is a Barcelona-headquartered, privately held supplier of maritime aids to navigation and marine infrastructure, founded in 2004 and operating as part of the Spanish Grupo Lindley group, with an additional office in Vigo following the 2022 AISTER Marinas acquisition. The company's core offering is split between (i) marine aids to navigation — navigation buoys, beacons, lanterns, electronic aids such as AIS and racon, elastic mooring systems, and remote monitoring solutions — and (ii) marina and harbour infrastructure, distributed in Spain through its flagship partnership with Lindley, comprising concrete, steel, aluminum and timber pontoons, floating breakwaters, access bridges, service pedestals, and boatyard equipment. Its business model is project-based capital equipment sales to a mix of government maritime authorities, port authorities, and private marina operators across Europe, Latin America, and Africa, supported by an installed base spanning more than 27 countries and by exclusive distribution rights for Hazelett Marine's elastic mooring systems in Spain. Differentiated positioning rests on regulatory credentials — IALA membership since 2008, IALA Code of Conduct adherence from June 2023, and ISO 9001:2015 and ISO 14001:2015 certifications — combined with bundled cross-vendor integrations (Sabik/SPX LightGuard monitoring, Hazelett mooring, Lindley pontoons) that let Almarin bid for integrated tenders rather than single-product sales.
