In order to meet the needs of independent innovation and development on China's naval architecture and marine engineering, during the 13th International Shipbuilding, Marine Equipment and Offshore Engineering Exhibition for China (October 24th to 25th), theresearch units of innovative project of the numerical tank (phase I) held an industrial application workshop on the China Numerical Tank (Version 1.0). 13 virtual test products, including the products of ship seakeeping motion and ship added resistance, were launched in this workshop.

This industrial application workshop was held by Researcher Zhao Feng from China Ship Scientific Research Center, Professor Zhao Binbin from Harbin Engineering University and Professor Dong Guohai from Dalian University of Technology. More than 20 industrial departments from shipyards and design institutes in Dalian, Shanghai, Wuhan, Beijing, Yantai and other places attended the seminar.

Professor Xia Guihua, the chief executive of the project, deputy secretary of the Party committee of Harbin Engineering University, introduced the general information and the primary methods of serving industrial users of the 13 virtual test products of the numerical tank launched this time.

Professor Zhao Binbin introduced the general information of the China Numerical Tank. Also, the virtual test products of ship seakeeping motion, ship added resistance of China Numerical Tank (Version 1.0) were introduced in details.

TheChina Classification Society (CCS) and the Bureau Veritas (BV) made reports onIntroduction on the China Numerical Tank Certification by CCS and Discussion and Application of Certification Technique on Numerical Tank, respectively. In these reports, the works on the certification of the China Numerical Tank were introduced.

The products launched this time were introduced in details by all research units of this innovative project of the numerical tank (phase I),including function, simulation accuracy, efficiency, characteristic, operation process and the situation of probation.

The China Ship Scientific Research Center (Shanghai) made a report on the test results of ship added resistance by using the China Numerical Tank. It was indicated that in most cases, the virtual test results showed good agreement with the experimental results. Especially for the low-speed cases,it was rare that the virtual test results agreeed well with the experimental tests, and the calculation efficiency was very high. The virtual system of ship added resistance provided by the China Numerical Tank will play an important role in the process of the China's submission of proposals for minimum propulsion power to the MEPC.

CIMC RAFFLES (Yantai) made a report on testing the virtual experiments on motions and loads of an ocean platform under the working conditions by the China Numerical Tank. The report pointed out that the calculation accuracy of this product was same as the accuracy of business software. Thus, it can be used to satisfy the design requirements. CIMC RAFFLES (Yantai) also gave some suggestions to improve the interface. It was hoped that the use of the China Numerical Tank will replace the business software gradually.In the process of industry users' experience and communication, participants watched the usage demonstration of the 13 launched products and experienced these products in person.

In industry, it is generally believed that the virtual experiment system of the China Numerical Tank has advantages in simulation accuracy, efficiency and usability, which greatly improve the China's independent innovation ability. The China Numerical Tank will help design the marine platforms, and provide strong guidance for the optimization design of naval architecture and marine engineering.

The China Numerical Tank provides free cloud service for 13 products to global users by parallel resource of 3000 cores. Users around the world can conduct virtual tests of numerical tank for naval architecture and marine engineering via the cloud portal atwww.numericaltank.com.
