HCSR

01/01.1970

1. Introduction COMPASS HCSR software , developed by CCS, is based on IACS CSR BC & OT(Common Structural Rules for Bulk Carriers and Oil Tankers),which evaluates prescriptive requirement and direct strength analysis of hull structure. It is constituted by two modules, one is prescriptive requirement check - structure design program (SDP), and the other is direct strength analysis (DSA).COMPASS HCSR software  has the independent intellectual property rights owned by CCS, and is updated with IACS HCSR progress. The software will provide strong support to the application of HCSR in China ship industry.   COMPASS HCSR(SDP BC)   COMPASS HCSR(SDP OT) COMPASS HCSR(DSA) Bulk Carrier                                       Tanker   2.HCSR SDP——Prescriptive rule check Features: 1 complete coverage of CSR BC & OT prescriptive requirements: calculation covering the whole ship.

Compared with CSR, CSR BC & OT focuses on the computational analysis and is more comprehensive and reasonable. In this situation, ship design, research, plan approval and inspection will be more dependent on CSR BC & OT software. The COMPASS-HCSR software is developed by China Classification Society and has independent intellectual property rights, which completely fulfills the IACS CSR BC & OT rules requirements. It is designed in accordance with the industry tradition which achieves high level in practicability, usability, flexibility, and efficiency. The analysis results are accurate and reliable. With the application of IACS CSR BC & OT, COMPASS HCSR software will strongly support and be wildly used in the ship design,ship development, plan approval and inspection.

CSR-DSA

01/01.1970

 COMPASS-STRUCTURE-CSR-DSA: Direct structural analysis (DSA) is developed in accordance with IACS Common Structural Rules for bulk carriers and oil tankers and on the basis of MSC.Patran. Due to complicated nature of CSR, traditional manual calculation approach spends great amount of time on load determination, corrosion deduction and result processing. Moreover, direct calculation is greatly increased in CSR due to the addition of more conditions and the introduction of fine mesh and very fine mesh analysis. DSA uses Patran’s PCL language and presents flexible assessment approaches, and hence greatly reduces calculation period in finite element modeling and increases analysis efficiency, to enable engineers to complete FE analysis quickly and accurately. Feature and functions: 1 Having a diversified rich marine profile database; 2 Capable of automatic loading according to the requirements of CSR, and hence avoiding the tedious manual loading process; 3 Capable of automatic boundary constraining; 4 Capable of corrosion deduction; 5 Providing powerful postprocessor approaches including buckling assessment, automatic mesh refining and fatigue calculation, etc; 6 Easy to learn and use; 7 Performing accurate and reliable calculation; 8 Updating with latest CSR.

Scientific Research on Rules

11/13.2020

The China Classification Society (CCS) is the only professional organization engaged in the ship classification survey business in China and a full member of the International Association of Classification Societies (IACS). CCS formulates classification rules for ships and offshore installations and is entrusted by China MSA to prepare technical regulations for ships and offshore installations. CCS has scientific research information institutions such as the Rules and Technology Center (CCS Shanghai Rules & Research Institute), CCS Wuhan Rules & Research Institute, Offshore Engineering Technology Center, Technology Research and Development Center, Science and Technology Innovation Test Center, and Information Center.Since its establishment, CCS has gradually formed a system of rules and regulations for sea-going vessels (including ocean-going fishing vessels), inland vessels, offshore mobile drilling vessels, fixed platforms, and container ships through the study of international advanced technical standards and the accumulation of experience in the process of plan approval and survey. The system of rules and guidelines for ships covers high-tech ship types such as very large crude carriers (VLCC), very large container ships, very large ore carriers, membrane liquefied natural gas (LNG) carriers, and large vehicle carriers, supporting the development of the shipbuilding industry in China, and promoting the safety of water transport.CCS concentrates its efforts on the research of key technologies for large and high-tech ship types and for offshore engineering, green smart technologies, and new energy application technologies, and has issued standards such as the Rules for Green Eco-ships, Rules for Intelligent Ships, and Rules for Cruise Ships. The rules for the structure of bulk carriers and oil tankers have passed the International Goal-based Ship Construction Standards for Bulk Carriers and Oil Tankers (IMO GBS) audit without defects, and the audit results are the best among the members of the International Association of Classification Societies. Fruitful results have been achieved in the research of key technologies such as intelligent ships/unmanned ships, application of LNG power on water, very large container ships, very large ore ships, LNG carriers, mobile platforms and floating units, reaching the international leading or advanced level. A large number of very large, high-performance, high-value-added ships and offshore mobile platforms have joined CCS. The system of CCS rules and standards and the technical service capabilities are widely accepted by international and domestic industries.CCS continues to increase its influence in the international maritime community, providing strong technical support for the Chinese government to participate in international maritime affairs, safeguard national maritime rights and interests, and support the development of related industries. CCS actively participates in the formulation of international maritime technical standards and submits more than half of the Chinese proposals to the International Maritime Organization on an annual average basis. CCS has played an important role in the formulation of international maritime technical standards including the Ballast Water Management Convention, Hong Kong Convention, Common Structural Rules for Oil Tankers and Bulk Carriers, Energy Efficiency Design Index for new ships, Code on Noise Levels on Board Ships, Polar Code, IGF Code, and asbestos-free thresholds, safeguarding the interests of the country and related industries, and making great contributions to the development of international maritime technology.In the future, CCS will continue to improve its capabilities in scientific and technological innovation and leading development, to comprehensively form a scientific and technological work system with the ability for strong independent innovation, high-level rules and standards, and scientific evaluation and experiment, and fulfil the mission of “safety, environmental protection, and creating value for clients and the society”. For more details, please contact us:Sea Ship: CCS Shanghai Rules & Research Institute, Tel: 021-61089200, E-mail: ccssr@ccs.org.cnRiver Ship: CCS Wuhan Rules & Research Institute, Tel: 027-85822350, E-mail: ccswra@ccs.org.cn Offshore Engineering: Offshore Engineering Technology Center, Tel: 022-62022888, E-mail: ot@ccs.org.cn
