Ottomarino Oy

Based in Kokkola, Finland, Ottomarino Oy is a specialized maritime service provider focused on commercial diving, underwater construction, and marine infrastructure maintenance. Established with a core emphasis on subsea engineering, the company supports a diverse range of clients, including port authorities, shipping lines, energy companies, and industrial facilities. Operating primarily within the challenging aquatic environments of the Finnish coast and the Gulf of Bothnia, the enterprise has developed expertise in managing projects that require precise technical execution beneath the water’s surface. The company’s primary operational focus lies in professional diving services designed to ensure the integrity and functionality of submerged structures. For the commercial shipping sector, Ottomarino performs essential maintenance tasks such as underwater hull cleaning and propeller polishing. These services are critical for vessel operators seeking to maintain fuel efficiency and reduce drag without the need for dry-docking. Additionally, the company conducts comprehensive underwater inspections using both divers and advanced imaging technology to assess the condition of ship hulls, identifying potential damage or fouling that could compromise seaworthiness. Beyond vessel support, Ottomarino plays a significant role in civil engineering and marine construction. The company’s teams are equipped to handle complex underwater construction tasks, including concreting, welding, and diamond drilling. These capabilities allow them to service critical infrastructure such as bridges, dams, and industrial water intake systems. The firm also manages the installation and maintenance of underwater cables and pipelines, executing the necessary trenching and embedding work to protect subsea utilities from environmental stress. In the sector of harbor and waterfront development, the company is active in the design, sale, and installation of floating dock solutions. While they serve private and recreational needs, their heavy-duty pontoon systems are also utilized in commercial marinas and port facilities. The organization’s scope extends to the dredging and clearing of waterways, ensuring safe depth and accessibility for marine traffic. By combining technical diving proficiency with construction management, Ottomarino provides a vital link in the maintenance of Finland’s maritime logistics chain, ensuring that vessels, ports, and underwater assets remain operational despite the harsh seasonal conditions characteristic of the Nordic region.
