OkeanOne operates as a specialized maritime technical services and representation firm, serving the global commercial shipping and offshore sectors. Established in 2015 and headquartered in Athens, Greece, the company functions as a strategic intermediary and service provider that connects shipowners and ship management companies with a network of technical solutions, repair facilities, and equipment manufacturers. Its primary mission involves streamlining the complex logistics of vessel maintenance, dry-docking, and afloat repairs by leveraging established partnerships with shipyards and service stations worldwide.
A central pillar of the company’s operations is its role as a representative for international shipyards. OkeanOne maintains commercial agreements with repair facilities in key maritime hubs, including locations in China, Turkey, Singapore, and the United Arab Emirates. Through these channels, the firm facilitates the scheduling and execution of dry-docking projects, conversions, and major structural repairs for large ocean-going vessels. Beyond static yard work, the organization manages a comprehensive network of underwater service providers. This division coordinates essential husbandry tasks such as hull cleaning, propeller polishing, and underwater inspections, including surveys conducted in lieu of dry-docking (UWILD), ensuring that fleets remain compliant with classification society standards without unnecessary operational interruptions.
In addition to facilitating major repairs, the company actively supplies technical personnel and specialized marine hardware. OkeanOne deploys "riding squads"—teams of certified welders, fitters, and painters—who board vessels to perform maintenance during voyages, thereby reducing downtime. The firm also operates a marine equipment distribution arm that supplies critical components such as marine valves, heat exchanger parts, boilers, and safety systems. This supply chain capability extends to modern environmental retrofits, including the installation support for ballast water treatment systems and scrubbers.
The organization serves a diverse client base that includes technical departments of shipping companies, primarily within the Greek and Turkish maritime communities, as well as broader international operators. By integrating shipyard representation, underwater technical coordination, and spare parts procurement into a single operational framework, OkeanOne assists maritime operators in maintaining vessel seaworthiness and managing the technical lifecycle of their fleets across global trade routes.
