ReTech SD Ltd.

Based in Varna, Bulgaria, ReTech SD Ltd. operates as a specialized marine engineering and design consultancy, serving the global shipping and offshore industries. The company focuses on technical solutions for vessel retrofitting, addressing the complex engineering challenges associated with integrating new mechanical systems into existing ship structures. Its operations center on the precision required to modify operational vessels, particularly when shipowners must adapt fleets to meet evolving international regulatory standards. The firm’s core competency lies in the execution of detailed onboard surveys and subsequent engineering studies. To ensure accuracy in the congested environments of engine and pump rooms, the company deploys survey teams to conduct high-definition 3D laser scanning on vessels worldwide. This process captures precise spatial geometry, allowing engineers to generate digital models that replicate actual onboard conditions. These digital assets form the basis for feasibility studies and basic design, ensuring that proposed modifications do not conflict with existing machinery, piping, or hull structures. Within the maritime sector, ReTech SD Ltd. plays a specific role in facilitating compliance with environmental mandates. A substantial portion of its engineering work supports the installation of Ballast Water Treatment Systems and Exhaust Gas Cleaning Systems. The company prepares comprehensive design packages that include piping layouts, structural foundation plans, and equipment integration schemes. These technical packages are utilized by shipyards and repair teams to execute retrofits efficiently, aiming to minimize the time a vessel spends out of service during drydocking or alongside repairs. Beyond environmental compliance, the organization handles broader scopes of naval architecture and marine engineering. This includes generating production documentation, such as isometric drawings and material lists, as well as providing the technical drawings necessary for classification society approval. By bridging the gap between theoretical design and physical installation, the company supports technical management teams in maintaining fleet operational readiness through structural and mechanical updates. The firm remains strictly service-oriented, delivering the intellectual and technical planning required to modernize maritime assets rather than manufacturing hardware or equipment.
