The Challenge
Delta Marine Industries Inc., a leading megayacht builder, faced a significant challenge in meeting the high customization demands of their clients. The company's clientele, purchasers of 100-foot plus megayachts, expected the ability to highly customize the interior design of their yachts. This demand for customization, particularly the freedom to place walls or partitions wherever desired, created structural design challenges by increasing the complexity of the load paths. The non-alignment of pillars made it difficult to determine how loads would distribute across various structural elements. Traditional design methods were inadequate due to the highly nonlinear and difficult to discretize load paths. Furthermore, Delta Marine was tasked with building a megayacht that not only had a luxurious interior and high cruising speed but also optimized weight and structural elements for strength and vibration resistance.
About The Customer
Delta Marine Industries Inc. is an award-winning yacht builder and one of the world's leading builders of megayachts. The company boasts a team of naval architects, marine engineers, and skilled workers with years of experience in specialized fields. Delta Marine expertly combines old-world craftsmanship with the latest technology to deliver high-quality, customized yachts to its clients. Their clientele primarily consists of purchasers of 100-foot plus megayachts who expect high levels of customization in the interior design of their yachts.
The Solution
To overcome these challenges, Delta Marine utilized ANSYS Mechanical, a simulation software. The company modeled the yacht's major shapes in Rhinoceros and imported them into ANSYS Mechanical. They used composite shell elements to model the laminate stack and solid elements for scantlings parts cast in resin. This approach allowed them to evaluate global and local stresses, simplifying the design of plating, beams, and pillars. They also used FE reports to detail and defend structural decisions that regulatory rule books could not adequately cover. Additionally, they performed a modal analysis to identify critical modes of vibration and addressed high bending moments by strengthening the hull and decks in areas of high bending. This solution enabled the designers to place walls and partitions wherever they wanted while maintaining strength, keeping the weight to a minimum, preventing vibration, and delivering a high level of performance in a luxury yacht that is aesthetically pleasing.

Continuous Casting Machines in a Steel Factory
With a very broad range of applications, steel is an important material and has been developed into the most extensive alloy in the engineering world. Since delivering high quality is absolutely crucial for steel plants, ensuring maximum productivity and the best quality production are the keys to competitiveness in the steel industry. Additionally, working conditions in steel factories are not suitable for workers to stay in for long periods of time, so manufactures usually adopt various machines to complete the steel production processes. However, the precision of these machines is often overestimated and the lack of flexibility also makes supervisors unable to adjust operating procedures. A renowned steel factory in Asia planned to improve its Distributed Control System (DCS) of furnaces as well as addressing the problem of insufficient accuracy. However, most well-known international equipment suppliers can not provide a satisfactory solution and local maintenance because the project needed new technologies to more accurately control equipment operations. By implementing Advantech’s automated monitoring and control solution, steel factories can not only improve the manufacturing processes but can also allow users to add additional functions to the existing system so as to make sure the operation runs at high efficiency.
