DEVELOPMENT OF PROPOSALS FOR OPTIMIZATION OF THE SHIP DESIGN PROCESS BY IMPLEMENTING A CAD SYSTEM AT THE EARLY STAGES OF DESIGN

Abstract

The purpose of the article is to develop proposals for optimising the ship design process by introducing a computer-aided design system for creating a digital model at the early stages of designand production, from conceptual design to operation. This goal is achieved by analysing the problems of using 2D models and the directions of implementing 3D models at all stages of ship design. This article discusses a possible solution to the problem of inefficiency in the early stages of design, which are still based on 2D drawings. The industry needs a new 3D approach, which will include changing procedures and using the appropriate CAD tool to create a digital model in the early stages of design and production, from conceptual design to operation. The proposed proposals will, for example, improve the determination of compartment layout and equipment positioning using 3D models, improve the basic design phase by reusing data already developed in the overall ship model, and define models as a 3D structure. It is also possible to perform an early assessment of materials, scales and related processes and use the topology to consider design alternatives and obtain early information on procurement and fabrication of materials. It is proved that to simplify the 3D model, all structural objects can be subjected to the idealisation procedure, namely the removal of notches, chamfers, macro-holes from profiles; topological expansion of surfaces; stitching of surfaces along the joint line, etc. The most significant result is the development of proposals for optimising the ship design process by introducing 3D models at the early stages of design and determining the benefits of the relevant approach. For further development, it is necessary to improve 3D modelling in two directions: first, to create clear and high-quality models with the possibility of optimising and simplifying them for the most efficient use; second, to develop a simple and adaptive solution for designers who usually use 2D tools for conceptual and basic design.
