ICCAS 2017, 26-29 September 2017, Singapore ICCAS 2017 – ACCEPTED & RESERVE ABSTRACTS 1. Development of Ship structural design and 3. Integrated Quantitative Risk Assessment for assessment system based on Harmonized Marine LNG Systems CSR Byongug Jeong, Byung Suk Lee, Peilin Zhou, Hogyun Park, Korean Register, Korea Department of Naval Architecture, Ocean and Marine Engineering, University of Strathclyde, UK IACS CSR-H (Harmonized Common Structural Rule) for Tankers and Bulk Carriers has been effective on July 1 This paper sets out an integrated quantitative risk 2015. CSR-H requires much more engineering efforts assessment method and introduces a software tool which and time especially than their predecessors, making the is able to facilitate the assessment of fire/explosion risks user-friendly software be needed for shipbuilders and for marine LNG process systems. The software (named classification societies. Using CSR-H software, ship IQRA) calculates the impact of jet fire, pool fire, flash designers are able to design ship structure efficiently and fire and explosion for varying leak cases under process accurately. Especially, the fine mesh verification is to be conditions. This function, coupled with a frequency performed fine mesh analysis for the various structural calculator, allows the risks to be estimated in one details. It is included in SeaTrust-HullScan, which is the environment. The program also provides a facility to structural design assessment software of KR (Korean carry out a range of parametric analysis so that designers Register) that has been adopted and being used in all and rule makers can identify the influence of parametric shipyards in Korea changes, which, we believe, is a feature very helpful for providing comprehensive guidance for safe design and rule-developing. Flexible frequency data input and 2. Improving shipyard steel material handling selectable consequence models help the users to identify using computer simulations the sensitivity of data/model selection and assist the process designers to compare process alternatives, check Ujjawal Chauhan, IIT Kharagpur, India design quality, and evaluate appropriate design options at design stage. Moreover, the built-in hierarchical "With today’s technology, it has become easier to create modelling of systems enables the overall risk of highly and implement shipyard processes driven by algorithms. complex process systems to be assessed with confidence Leading players in shipbuilding and shipping industry based on historical failure data on component level. such as Maersk and Hyundai are using analytics to their Finally, this paper demonstrates the effectiveness of this advantage. However, despite all these technological tool by discussing several case studies investigating the advancements, one of the key complexities that remain to potential risk of LNG systems. be tackled is that of material handling, especially in steel stockyards. One of the problems that a country like India Keywords: IQRA, LNG safety, quantitative risk currently faces, due to its absence of large scale assessment software, hierarchical modelling method, shipbuilding culture, is the lack of large scale expertise in parametric analysis complexities of material handling and lack of adequate research into digital infrastructure to tackle the problem. However, the entry of private firms in Indian 4. Improvements in Learning Process and shipbuilding industry in last several years is slowly Productivity. An Analysis of the Return of changing this outlook. the Investment The present work formulates a framework for material Rodrigo Perez, SENER, Spain management in steel stockyards by considering the scheduling of crane and also proposes a simulator for CAD Systems help engineers and designers in various operational efficiency to reduce handling times. The said industries, designing and building 3D models of simulator shall help not only in monitoring of stock but airplanes, bridges... and of course, ships, submarines and also support decisions on layout designs based on floating structures. Nowadays all the industry, an parameters such as size of stock and production especially shipyards and design offices, uses CAD in requirements. " order to design better and cheaper boats and floating artefacts. The use of a CAD System provides not only a cost reduction in design, but also a cost reduction in production, including two major aspects: savings in materials due to a more accurate definition of components and material management, as well as savings in materials due to a significant reduction of design The Royal Institution of Naval Architects 1 ICCAS 2017, 26-29 September 2017, Singapore changes, and consequently reduction of rework in 6. Single Source Data – Help or Hindrance production; and savings of production man-hours due to the reduction of changes and rework. J L Martin, SAMOSC Ltd., UK This paper shows an analysis performed with information There is a continuing drive towards single large volume compiled as a consequence of the author experience in database systems to integrate all data created and used in CAD implementation in numerous shipyards around the a shipyard. “Single Source of Data”, “Shared Data world during the last years, to provide a clear idea of the environment”, “Enterprise Architecture”, “Product Return on Investment of using CAD Systems (in Lifecycle Management”, are all marketing expressions particular, the FORAN system) in a generic shipyard. used to describe a shared data capture and management Another key aspect of this paper, is the analysis of the system for use across all departments involved in ship learning curve of a new CAD System implemented in a design, manufacture, build and in-service support. generic shipyard. The data, hours expended designing blocks and units of different weights, collected for this The single source data concept removes the need for paper during a couple of years from a generic shipyard, numerous interfaces and the complexities of duplicated have been a fantastic tool for analysing the factors that data quality and integrity management. A comprehensive affect a learning curve process. shared data environment is presented as the ultimate in efficient data capture, storage and management, with claims of considerable benefits and advantages from use 5. Ensuring Software Reliability, Safety, and of inclusive database systems technology in a shipyard. Security However, it is often assumed that ALL data captured David Card, DNV GL, USA during the lifecycle of a ship must be included in the single source database irrespective of its use, with This article describes the motivation, approach, and superficial regard for logical categorisation or data results of an effort to introduce modern software quality modelling. This results in a database unnecessarily very assurance practices into the construction of mobile large, convoluted, difficult to control, clogged up with offshore drilling units (MODUs). This approach is superfluous data, and difficult to interpret. applicable to the construction of other complex vessels such as cruise ships and LNG carriers where reliability, For an effective and efficient single source database, safety, and security are principal concerns. careful consideration must be given to the format content, quality, categorisation, and lifecycle use of all DNV GL published the optional class notation OS D- data items. 203, Integrated Software Dependent Systems (ISDS), in 2010. ISDS defines a set of best practices for software This paper describes the data and information engineering and system integration, based on generic considerations necessary when implementing a shared international standards.
