REISIN OU is a maritime service provider headquartered in Estonia, functioning primarily as a ship’s agent and vessel support entity dedicated to operations within the Baltic Sea and the Gulf of Finland. The company serves as a critical liaison between ship owners, charterers, captains, and port authorities, managing the complex logistics and formalities required when vessels enter Estonian waters. Its core mandate is to facilitate efficient port calls and turnarounds, operating on a twenty-four-hour basis to accommodate the unpredictable schedules inherent to international shipping.
A significant component of the company’s operational profile involves acting as a port agent in Tallinn and other Estonian harbors. In this capacity, REISIN OU handles essential documentation, customs clearance, and immigration formalities, ensuring that vessels comply with local regulations upon arrival and departure. Beyond standard port calls, the company has developed specialized capabilities in handling operations at the Tallinn Outer Port Limits (OPL). By coordinating services at anchorage rather than requiring vessels to dock, the company enables ship operators to perform crew changes, receive spare parts, and restock provisions with minimal deviation from their main routes, thereby reducing downtime and port costs.
Technical support and vessel maintenance represent another pillar of the company’s portfolio. REISIN OU provides comprehensive underwater husbandry services, employing divers and remotely operated vehicles to inspect hulls and underwater machinery. These services include hull cleaning and propeller polishing, which are essential for maintaining vessel fuel efficiency, as well as underwater blanking operations and general repairs. The company also oversees the cleaning of cargo holds, preparing vessels for new freight assignments.
Environmental compliance and safety services further define the company’s role in the region. REISIN OU manages the reception and disposal of ship-generated waste, including sludge and bilge water, assisting vessels in adhering to international environmental standards regarding deslopping. Additionally, given the challenging winter conditions of the Baltic region, the company offers ice advisory services. It coordinates experienced ice advisors to assist captains in navigating frozen waters, ensuring safe passage through the Gulf of Finland during the winter months. Through these varied maritime activities, REISIN OU supports the operational continuity of merchant vessels transiting Northern Europe.
