Product regulations specify requirements or constraints for products that manufacturers must comply with across the entire product lifecycle, from design and manufacture, through operation and maintenance, to recycling and disposal. This paper suggests a system framework and its essential components for the verification of a pressure vessel design using the industrial standards of Korea. The authors also present methods to generate design template data from legacy design systems and to construct a regulation knowledge base. The proposed framework is demonstrated through experiments involving pressure vessel design verification using a prototype system. © 2015 The Korean Society of Mechanical Engineers.

In the shipbuilding industry, different computer-aided design (CAD) systems are used for different design domains, structure, and outfitting. We need to exchange data among different CAD systems such as Tribon, AutoCAD, Intergraph or PDMS to complete the whole design and production process. There are two approaches to data exchange. One is direct translation; the other is indirect translation, which is based on a neutral format. If we use a neutral format, the data specification is open to the public and the design model can be used by other CAD systems, including next-generation CAD systems. In this paper, we propose an indirect method that uses ISO 10303 (STandard for the Exchange of Product model data) AP227 and ISO 15926 to define neutral formats. A separate ShapeDB is constructed to manage the geometry information, referenced to the catalogue data defined by ISO 15926. An experimental implementation for data exchange between Tribon and PDMS is described. © 2010 JASNAOE.

When designing a product, a designer has to follow regulations involved in all phases of product lifecycle. However, it may be practically impossible for a designer to be well-acquainted with all the regulations related to a product. Therefore, from the viewpoint of a company's competitiveness, it is important to provide a tool which automatically checks design results of a product in accordance with the regulations involved. Outsourcing a design checking service instead of in-house development can be an appropriate choice, considering facilities, human resources, and cost required for developing and managing design checking tools. In this paper, the authors suggest a method to prevent the leak of intellectual property, which may occur when providing design checking services. This work also discusses necessary data exchanged between a design checking service provider and a manufacturer. Furthermore, this work details design checking service procedure and system architecture of a design checking service. © 2012 Elsevier B.V. All rights reserved.

3D CAD data have not only part geometry but also product structure information and manufacturing-related properties. Visualizing part geometry with these data on internet is useful in downstream product development. Web visualization standards provide a way to develop visualization tools independent from a CAD system. This paper proposes a method for using the X3D visualization standard to include part geometry, product structures, and manufacturing-related properties simultaneously. 3D CAD data are extracted from a CAD system and translated into the X3D standard. A translator system and a web viewer system are implemented to verify the proposed approach. A test using three different 3D CAD files is conducted to evaluate the performance of the proposed approach. According to the results, the proposed X3D data set is better visualized than data in the VRML standard. © 2015 Elsevier B.V. All rights reserved.

Oil majors have operated Offshore Platforms in more than 25 years and they need to evaluate the options of life extension or decommission over the computing residual life. In order to manage this trend, DNV-GL and ABS are reinforced both engineering services and software with the expectation for the expansion of the market based on Regulatory requirements. When considering offshore platforms lifetime management, the platforms age and degradation or deterioration loads based on a specific environment needs to be regarded. This study explains the trend of life time management in Oil & Gas Industry, especially for Offshore Platforms, and introduces a Condition based maintenance (CBM) system to integrate information related to diagnosis, assessment, prognosis and maintenance for the offshore platform's state on the basis of Engineering Data comparison methodology. With a traditional approach, it took months to make a report for the behavior based load analysis, based on data obtained from IMMS (month / quarter / half year / year). With the CBM concept system, especially Data comparison method, Design, Operation and Maintenance department can analyze fatigue life and predict the residual life within a week so that all interested parties can reduce costs and time through an effective decision process.

In 2014 Williams Companies delivered a Spar-based FPS to be used by the Hess Corporation for developing their "Tubular Bells" field as well as for future tiebacks for other developments. Tubular Bells is located in the Mississippi Canyon region of the Gulf of Mexico. The Spar hull is the 'Classic hull form', 584 ft (178 m) long, 85 ft (26 m) in diameter with 60 ft (18 m) hull freeboard. The mooring system consists of 9 mooring lines in 3 groups composed of a chain-polyester-chain configuration. This paper describes the tools and methodology Williams plans to use for assessing the fatigue damage of the mooring chain over the operating life of the platform. The basic plan is to collect field-measured data for parameters that impact mooring fatigue damage, such as: environmental conditions, Spar motions (particularly Vortex Induced Motions data) and mooring line tensions, then process that data with specialized software so it can be effectively compared to the applicable data that was used in the design of the mooring system for fatigue. A key element in the plan to compare the field data with the design data is new computer software developed specifically to process the field measured data and generate the field measured, fatigue design parameters on a regular basis and in a form that is readily comparable to the design data. Additionally, a graphic user interface in this software will provide a clear visualization of the Spar motions that is linked with the associated environmental conditions for the same time periods. © 2015 by ASME.

Future Application and Middleware Technology on e-Science | Year: 2010
Virtual digital mock-up (v-DMU) refers to all of the activities in the design, analysis, and visualization of the product in a 3D virtual environment that lead to a lower cost and a higher quality. In the early days, designers exchanged CAD files directly in collaborations. Recently, DMU systems have been used for relatively effective designs that generally support distributed and collaborative design capability by sharing the design data via the Internet. However, a range of problems can arise in such a case. In the case of large-scale products such as aircrafts or ships, the data size can be on a scale so large that it requires large amount of space on the workstation and requires considerable time for exchanges. Moreover, security problems often occur in the process of data exchanges. For a company and a nation, this can be crucial. The immersive visualization of product design data is becoming more important in collaborative design. As a solution to these issues, this paper proposes a new approach using the technology of the remote visualization of CAD data. This involves the streaming of rendered graphics using COVISE and SAGE. This paper also introduces the implementation of v-DMU based on e-Science by remote visualization. © 2010 Springer Science+Business Media, LLC.
