NAVAL ARCHITECTURE
Naval Architecture
21 Knots provides solutions for entire range of marine vessels’ basic and detailed design. We have an in-house collaborative team of Naval Architects and engineers. Our designs have been approved by all major Classification Societies across the world. We have worked with leading global shipyards to provide customized production design solutions.
We undertake ships’ hull form design, stability calculations, structural design, machinery sizing and arrangements, process engineering, electrical design and system integration. Our team is well-versed in specialized software for all disciplines of marine design.
Ship Design
