... known as blocks. These blocks are individually constructed and subsequently assembled at the final workstation, denoted as the block joining station. Upon completing block fabrication, a deliberate tolerance allowance is retained on the plates to accommodate deformations induced by heat treatment during...

... is extremely time-consuming and laborious. The final hull is composed of intermediate products, such as subassemblies, unit assemblies, and grand-assemblies (Cho et al. 1999). Since the group technology was applied in hull construction, a series of production lines has been established based on the process...

... PRODUCTION AND DESIGN 173 to adapting their production toward lean manufacturing. The use of a PWBS shipyard organization enables the continually repetitive nature of assembled interim products such as unit panels and transverses, which form larger blocks when assembled together (Kolic et al. 2012). The task...

The welding process and the deformation pattern affecting the final shape of a block assembly...

..., the level of IHOP application differs among shipyards. There is still much rework and outfitting that is performed on the slipway or in the dry-dock as opposed to during the assembly or preerection construction phase. The main aim of IHOP is to construct and outfit and paint ship blocks to a high degree...

...-induced deformation creates a significant manufacturing challenge during fabrication of major ship assemblies, especially for thin-plate steel construction. The objective of this project was to improve weld sequence planning (WSP) capabilities for major ship assemblies through the development of a quick...

...Damir Kolich; Richard L. Storch; Niksa Fafandjel The main shipbuilding assembly processes greatly influence the flow of interim products in a newbuilding shipyard. The panel assembly line is a major process located upstream of all the other shipyard assembly processes. In a previous paper...
