In the shipyard, a lot of data is generated, stored, and managed during design, construction, and operation phases to build ships and offshore structures. However, it is difficult to handle such big data efficiently using existing data-handling technologies. As the big data technology is developed, the ship and offshore industries start to focus on the existing big data to find valuable information from it. In this paper, the material requirement estimation method of offshore structure piping ma

Traditionally, the initial ship design starts from a parent ship. The parent ship is given in the 2D lines form, i.e., the offsets. A designer modifies the offsets and gets the new hull shape that satisfies new design constraints. The offsets are used for the numerical analysis to evaluate whether the modified ship can meet the constraints. Generally, the mesh is generated for the analysis using the offsets. Sometimes, the initial ship is given in NURBS surface form instead of the offsets. In th

The initial ship design starts from a parent ship. A designer selects a suitable parent ship and modifies the hull shape for a new design. When a ship is modified, the hydrodynamic analysis such as numerical analysis, computational fluid dynamics analysis, model test, etc. is conducted, and the shape of the ship hull is changed according to the analysis results. This iteration continues until the owner’s, and Class requirements are met. During this process, it takes much time and high cost. In t
