Prescriptive rule requirements
5/16/2018 4:40 PM Prescriptive rule requirements The expression “in general” for the safety level and the principles Eliminated in the finalisation of the rules in some parts Has been used to allow some degree of redundancy and freedom in the structural design It becomes necessary to follow the detail requirements as written in the rule and makes homogeneity and uniformity All of vessels will have similar structures Is it true the detail structures defined by HCSR are the best ?

Availability of software tool
5/16/2018 4:40 PM Availability of software tool The software for HCSR provided by Classification Societies is indispensable Key points of the software for HCSR Easy input and easy modification of input data Full functions for creating FE model along the rules Calculation time without tediousness Ease of visual check of the output results Display function for deformation and principal stress Comprehensible reporting capabilities © 2008 Microsoft Corporation.

Fatigue evaluation Significance of the fatigue strength
5/16/2018 4:40 PM Fatigue evaluation Significance of the fatigue strength Fatigue crack may lead to function loss such as leakage from cargo tanks or fuel tanks Consequently financial damage could be tremendous Shipyards are often requested to make highly robust design and construction in terms of fatigue strength Outline of fatigue evaluation Focus on structural discontinuities and high stress area By prescriptive rules and FE analysis Evaluation by fatigue life of 25 years in NA © 2008 Microsoft Corporation.

Fatigue evaluation Credibility of the fatigue life of 25 years ?
5/16/2018 4:40 PM Fatigue evaluation Credibility of the fatigue life of 25 years ? Obtained based on the conditions set by HCSR The fatigue life of the same vessel may be different if evaluated by the former CSR and HCSR It may be possible that an oil tanker which had the fatigue life of 25y by the former CSR does not have the fatigue life of 25y by HCSR It is important to avoid the misunderstanding the ship designed by the former CSR and with lower evaluation by HCSR is less sound © 2008 Microsoft Corporation.

Fatigue evaluation Method for fatigue strength evaluation
5/16/2018 4:40 PM Fatigue evaluation Method for fatigue strength evaluation It is said that a definitive methodology for fatigue strength has yet to be established HCSR also inherits the conventional method, known as Palmgren-Miner Rule While Palmgren-Miner Rule is simple and practical, it does not take into account the effect of load history on the crack initiation time It is important to recognise that the fatigue life obtained from this method is merely an estimate © 2008 Microsoft Corporation.

Calculation reports Huge number of pages of calculation reports
5/16/2018 4:40 PM Calculation reports Huge number of pages of calculation reports Increased due to increase of number of analyses Several thousand pages in total per vessel Sometimes it depends on the efficiency of the software provided by the Classification Societies Is it possible to check the details of calculation outputs by class surveyors and shipowners ? The adequacy of analyses needs to be checked with engineering sense by ship designers and class surveyors The calculation reports are very important documents so intellectual property should be strictly controlled © 2008 Microsoft Corporation.

Views on HCSR from shipbuilding industry
5/16/2018 4:40 PM Views on HCSR from shipbuilding industry HCSR as text books for structural engineers The structural safety level has surely been enhanced in recent ten years by IACS members HCSR describe not only structural requirements and also details of design standard and criteria, like as a text book It will lead to unification of the structural design of each shipbuilding company There are pros and cons @ It will raise the safety level of all shipbuilders @ It will restrict the freedom of the design and future design advancements © 2008 Microsoft Corporation.

5/16/2018 4:40 PM Views on HCSR from shipbuilding industry What is the differentiation of each shipbuilder ? The only way is to secure and increase the structural quality with appropriate cost For example, even for two oil tankers that are made according to the rules that have the same plate thickness, scantling and almost identical designs, the final quality and actual strength level of hull structures would be different depending on the extent of quality assurance during the building process The quality of welding and accuracy control of structural connections significantly will affects the actual strength It is the responsibility of shipbuilders to secure a high level of structural quality which will lead to the differentiation © 2008 Microsoft Corporation.

5/16/2018 4:40 PM Views on HCSR from shipbuilding industry Follow-up of the former CSR and HCSR An evaluation of oil tankers designed by the former CSR and HCSR is needed after delivery to check the adequacy of the rules and the construction quality If a structural damage occurs to the hull structure, the reason should be duly investigated and evaluated IACS is kindly requested to share the information of damages with industries and IMO These actions are requested for the transparency and the validation of both CSRs IACS should be able to explain to shipowners whether the former CSR ships have sufficient structural safety © 2008 Microsoft Corporation.

5/16/2018 4:40 PM Views on HCSR from shipbuilding industry Goal of the Rules ? It is easy to make the rules relatively enhanced compared to the conventional ones It is a responsibility of IACS to judge the reasonable and necessary extent of strictness Shipbuilding companies have been investing human and financial resources for application of the CSRs The corresponding cost increase will affect the ship owners in the end It is our desire that IACS takes into account the economical as well as technological points of view when considering how to enhance the rules © 2008 Microsoft Corporation.

5/16/2018 4:40 PM Conclusion How should shipbuilding industry respond to the new era of HCSR ? We need to make effort to minimise the increase of the design workload, thus the design cost which may affect the cost for shipowners For the good efficiency of the structural design, it is necessary not only to review the design process and use the software provided by Classification Societies, but also to develop supporting software © 2008 Microsoft Corporation.

5/16/2018 4:40 PM Conclusion The improvement for more efficient submission and approval process of the design information is necessary to be considered for both shipbuilders and Classification Societies It would be necessary to not only make electronic version of calculation reports but also efficiently make summary reports for the good understanding of Class.

5/16/2018 4:40 PM Conclusion After application of HCSR to real ships it is necessary to check the difference of scantlings between HCSR and the former CSR in any shipyard and for any type of vessel These evaluation results should be summarised and given to IACS as feedback for the help of the rule verification © 2008 Microsoft Corporation.

5/16/2018 4:40 PM Conclusion Shipbuilding industry should flexibly respond to the rules of HCSR and continue making effort toward further enhancing the safety and reliability of the hull structures of oil tankers Shipbuilding industry should minimise the cost increase factor due to the new rules by their own creative effort, creating stronger cooperation with IACS members to build oil tankers that are not only robust but fit for the purpose intended © 2008 Microsoft Corporation.
