Dolphin LTD

Based in Tallinn, Estonia, Dolphin LTD is a specialized technical service provider dedicated to the maritime and shipbuilding sectors. Operating primarily within the Baltic region and extending its services internationally, the company functions as an independent engineering consultancy and inspection body. Its core mandate is to support shipowners, ship managers, and shipyards during complex repair projects, construction phases, and mandatory classification surveys. Rather than manufacturing equipment, the company focuses on the structural integrity and technical compliance of marine assets, acting as a crucial link between vessel operators and repair facilities. The company’s operational expertise is centered on Hull Structure Surveys and technical supervision. A significant portion of its work involves Ultrasonic Thickness Measurements (UTM), a critical procedure required by classification societies to assess the condition of a ship’s steel plating. By monitoring corrosion levels and material degradation, Dolphin LTD helps vessel operators determine necessary steel renewals, ensuring that ships remain seaworthy and compliant with international maritime safety standards. This capability is complemented by Non-Destructive Testing (NDT) services, which allow for the detection of internal flaws or welding defects without damaging the vessel’s structure. Beyond diagnostics, Dolphin LTD provides active supervision for steel repairs. Their engineers oversee the quality of welding and structural modifications, verifying that work performed by shipyards meets specified technical requirements. This supervision includes calculating metal weights and auditing invoices, a process that protects shipowners from commercial discrepancies while ensuring technical precision. To access difficult-to-reach areas of a vessel, such as high masts, cargo holds, or external hull sections, the company employs industrial mountaineering techniques, also known as rope access. This method often eliminates the need for costly scaffolding or dry-docking for minor inspections. Adapting to modern maritime trends, the company has integrated remote inspection technologies into its workflow, utilizing drones for visual surveys of large or hazardous structures. This approach reduces risk to personnel and accelerates the inspection process. Through its combination of traditional engineering oversight, advanced diagnostic methods like UTM and NDT, and modern access solutions, Dolphin LTD maintains a focused role as a technical guardian of vessel structural health, ensuring that maintenance and repairs satisfy both customer expectations and rigorous classification society rules.
