A strategy is necessary to improve the assembly process of super yachts. Literature on improvement methodologies from different industries suggest that a reduction of system complexity can lead to a more efficient assembly process. A less complex system in terms of assemblability can be achieved by modularization of these systems. Literature suggest that the performance of a modular strategy can be further elevated by with a strategy called “design for assembly”. The System Coupling Level Index is adapted for shipbuilding. A reduction in the complexity results in less human effort on-board. This enables the LSSI (Large Scale System Integrator) to positively change the value-time curve of the assembly process. The shift from on-board to a workshop enables the LSSI to outsource the production of the modules, this is indicated with the Production Multiplier (PMP) adapted from the 3C model. The outsourcing of these modules leads to a higher Gross Margin (GM) on the system for the LSSI. Moreover, the time effect is a reduced lead time of the engine room. A different machine install strategy can reduce the idle time of equipment in the engine room. This reduces the risk on damage of equipment and gives the suppliers more time to produce the modules.
