Improving the Shipbuilding Block Assembly Method: An Engineering Approach

Block construction is a modern shipbuilding method which involves the assembly of prefabricated modular sections. Cross-sections of the superstructure are pre-built in a shipyard, taken to the building dock, then hoisted into position and attached. Block splitting and lifting schemes are largely devised after the ship design phase is completed, relying on empirical data and expertise to avoid costly and potentially dangerous failures during build-up. Advances in computer-aided engineering (CAE), however, now make it possible to plan ship build-up in the principal design phase, giving designers greater insights into block assembly process outcomes and reducing downstream risk through simulation.
