In the competitive shipbuilding industry, gaining a competitive advantage between shipyards is necessary. A competitive and sustainable shipyard process must constantly be monitored to increase productivity, efficiency, and quality. One of the major concerns in modern shipbuilding is achieving efficient ship outfitting, particularly for high value-added ships. Maximizing the level of the ship’s equipment installation before launching is one of the essential goals in modern shipyards while outfitting after the launching tends to be reduced to a minimum. Therefore, this paper will analyze the current situation in the observed shipyard in general, mainly the ship modular outfitting concept, which could improve its characteristics and impact the ship production process. Hence, the modular outfitting approach’s benefits, requirements, and potential drawbacks will be discussed. The module assembly and installation activities will be established as a case study, including all necessary resources for the selected machinery module. A network diagram with a critical path will be provided for analysis while a digital computer 3D modelling and visualization of module assembly and installation is developed. Furthermore, such model authors plan to use in further research as a basis for ship design and production digital integration to support the digital transition of the shipbuilding industry.
