Lecture
■Japan Marine United Co., Ltd./ Mr. Hiroaki Ogawa
「Development of buckling / final strength analysis support tool for flexible panel」
Lecture summary
The buckling / final strength evaluation of the hull structure is very important in the ship design, and one of the evaluation methods is the FEM analysis method of the flexible panel. While this method provides highly reliable results, it’s extremely complicated and requires various MPC settings and initial deflection input. Therefore, we have developed a tool on TSV-Pre that can consistently and efficiently perform everything from model creation to analysis condition input. With this tool, the evaluation time has been dramatically reduced, and buckling and final strength evaluation can be performed in various cases.

■Hiroshima University / Ass. Prof. Satoyuki Tanaka
「Simulation of surface crack growth in a cylindrical joint」
Lecture summary
The simulation results of the growth of surface cracks generated at the weld toe of a cylindrical joint are reported. Using the fracture mechanics analysis function of TSV-Pre, the fracture mechanics parameters were calculated and the cracks in the curved surface shape were modeled by the tetrahedral quadratic elements. The results of examining the effectiveness and validity of this approach by comparing it with the crack growth phenomenon obtained by the fatigue strength test are shown.

■Samsung Heavy Industries／Mr. Jaehan Lee
「Simulation Study using TSV-BLS(TechnoStar-Block Lifting Simulation System) for Heavy Block Lifting By Giant Facilities in SHI(Samsung Heavy Industry) 」
Lecture summary
SHI is building many different types of vessels and marine structures with shorter delivery times each year. Therefore, the complicated studies are required to strictly evaluate the safety of block lifting work using various large equipment of shipyards for these large blocks. In order to carry out the examination work efficiently and easily and create a block lifting work plan. Currently, SHI is evaluating the validity and safety of the block lifting work procedure using TSV-BLS simulation. In this presentation, we will introduce the following research cases.
・Strength evaluation and buckling strength evaluation by lifting blocks
・Confirmation of interference by lifting blocks with accessories
・Strength evaluation of the Carrier

「Development of CSR-B direct strength analysis evaluation system using parametric modeling system TCAD」
Lecture summary
We have developed a direct strength analysis evaluation system based on CSR-B as TCAD / DSA under joint development with TechnoStar. The features of this system are parametric modeling using TCAD technology and a one-stop evaluation system that allows the automatic works from modelling to report output based on the EXCEL input data. In this lecture, we will explain the contents of the development system and report some application examples using this new tool.

「Structural analysis post processing software「Ship Post」Introduction」
Lecture summary
Until now, the “primary evaluation system” developed in-house about 20 years ago has been used for many years for structural analysis post-processing. However, because the software was old, I was dissatisfied with its usability and processing time. Therefore, the primary evaluation system has been renewed, and new software that incorporates efficiency and functional improvements in addition to the conventional functions.「Ship Post」was developed using TSV-Post as a platform. This time, we will introduce the background, functions, and prospects for future functional improvements that led to the development of 「Ship Post」.
Mr. Tokumoto talking about future functional improvements
■Tokai University / Professor Hideyuki
「Development of inboard noise prediction method and prediction program」
Lecture summary
The IMO inboard noise code has been amended to regulate inboard noise levels for vessels contracted after July 1, 2014. In order to satisfy the noise level regulation value, it is necessary to predict the noise level at the design stage and take appropriate measures without fail. In order to accurately predict the noise level, it is indispensable to construct an appropriate noise propagation model and prepare reliable vibration / acoustic characteristic data. We will introduce the development of a practical noise prediction program that combines the Janssen method and the SEA method.

■National Maritime Research Institute / Mr. Taketaka Ogawa
「Development of NMRI-DESIGN – An integrated analysis system for all ship loads and structures for advanced hull structure design」
Lecture summary
Due to the recent increase in size and new format of ships, there is a need for a wider range of strength studies than ever before. In addition, the development of computers and the formulation of the Goal-Based Standards (GBS) by the International Maritime Organization (IMO) are accelerating this trend. Against this background, the National Maritime Research Institute has developed NMRI-DESIGN – an integrated analysis system for all-ship load structures – to help examine structural design and standards based on a more rational evaluation system. In this lecture, we will introduce the outline of the system and verification examples. Furthermore, we have also developed a platform for processing these easily and at high speed in collaboration with TechnoStar Co. Ltd.
Mr. Ogawa talking about an example of fatigue strength evaluation by NMRI-DESIGN
■Nippon Kaiji Kyokai / Mr. Hiroshi Ochi
「Research and development of automatic modeling system for hull direct strength analysis (Introduction on the joint research and development of ClassNK）」
Lecture summary
In order to design and develop container ships and those ships that required to apply the harmonized CSR have been becoming larger in recent years, direct strength analysis using the FE model of all ships is indispensable. On the other hand, the existing FE Modeler has not been able to realize the initial design stage and short-term modeling required by the designer, as well as the flexible response to design changes.
In ClassNK’s joint research and development efforts, we are currently developing an efficient modeling system that supports the above, so we will introduce the concept.
