Ship building technology involves business-process technologies, system technologies, shipyard production-process technologies, and technologies for new materials and products. Advanced Shipbuilding Technology is used to make state-of –the art vessels and includes numerically controlled machine tools, robots, automated process control equipment, computerized flexible manufacturing systems, associated computer software, and other technology for improving shipbuilding and related industrial production. Advance technology incorporates novel techniques and processes designed to improve shipbuilding quality, productivity, and practice. The technology is environmentally sensitive so as to promote sustainable development through quality assurance, continuous process production technology, energy efficiency, waste minimization and design for recyclability or parts reuse. Advanced ship building technology also uses inventory management, upgraded worker skills, and concurrent engineering along with other elements contributing to a shipyard's efficiency or productivity assisting it to more effectively operates in the shipbuilding industry.

It withstands extremely harsh climatic and weather conditions. Hull should be designed in such a way that it is not affected by the different forces that acts on it while the ship is sailing. In this article we will have a look at different hull designs. Introduction The hull is one part of the ship that requires extra concern during design and construction. In the history of naval architecture , hull designs has evolved over a period of time, from cylindrical wooden shanks to steel columns. Engineers have been continuously innovating hull designs to provide greater structural strength. As hull is continuously in contact with water, it is under the effect of different types of forces acting at the same time. Not only that, a hull requires high durability and resistance to prevent structural damage in case of collision or grounding. Naval architects use different methods for hull construction keeping in mind the purpose and type of ship . In this article we will have a look at the basic ship hull designs which are commonly used. Terms in ship hull design For understanding a hull structure, it is important to know the basic terms. We will quickly go through the basic terms that are required to understand a design. Frame- It is a steel plate that runs longitudinally or transversely throughout the hull structure. Frames are welded to the sides of the hull as shown in the figure. They form the basis of any design and all hull designs consist of frames.
