The Exciting Numerical Wave Tank Technology
 
Numerical Wave Tank (NWT) is high-performance computation software, which is based on advanced hydrodynamic theoretical model and high-resolution numerical algorithms. Combining with advanced computer and Internet, the NWT can realize high-accuracy virtual test on hydrodynamic performance of ship and marine structure in variant sea states. Thus the NWT will be able to meet the needs of research, design and applications in naval architecture and ocean engineering after systematical verification and validation (V & V). The NWT simulates flow field, body motion and loads on structure by solving the governing equations based on advanced computer. The NWT can realize physical wave tanks functions and overcome its limitations. Therefore, it is helpful to design better optimized ship and offshore platform. The NWT has great significance in theory and application, since it is the most important technology for the transition from physical wave tank model test to virtual test in naval architecture and ocean engineering equipment R&D, and the revolutionary transformation in naval architecture and ocean engineering equipment design approaches.
 
The Numerical Wave Tank is to use advanced hydrodynamic theoretical model, sophisticated numerical algorithms and systematically compiled high-performance computing software, combining with advanced computer and Internet conditions to carry out the virtual experiments of the fluid dynamic response process on ship and the marine structure in different marine environments. Thus it will be able to meet the needs of ships and marine engineering on research, design and applications of engineering after having been tested and proved right. The basic idea/principle for Numerical Wave Tank is to use computer to simulate fluid flowing, solving the fluid moving equations and simulating the movement and the force undertaken by sea structuresusing software to realize functions that outperform the functions achieved with physical tank so as to design better optimized ship type and deep-sea platform. The technology was developed by Naval Architecture and Ocean Engineering Equipment and it is the most key supporting technology for the transition from physical tank test to virtual simulation and for the revolutionary transformation in design approaches in Naval Architecture and Ocean Engineering, carrying great significance in theory and engineering. 
 
Numerical Wave Tank Tests
 
 Ship Speed and Resistance Virtual Test
 Propeller Cavitation Exciting Force Virtural Test
 Ship Seakeeping Virtual Test
 Ship Maneuvering Virtual Test
 Marine Environment Virtual Test
 Motion and Loads of Offshore Platform Virtual Test
 Vortex Induced Vibration and Vortex Induced Motion Virtual Test
 Virtual test of full scale ship and offshore platform in real sea states can be realized in the future.
 
The Advantages of Numerical Wave Tank 
 
Traditional Physical Tank has the following drawbacks:
(1) A long testing cycle and high cost;
(2) Functions of present physical tank fail to meet new requirements;
(3) Limited in size, not able to simulate full scale ship;
(4) Space-time interruption becomes the biggest bottleneck for intelligent design.
 
The NWT can overcome the drawbacks of traditional physical tank mentioned above. During the initial stage of NWT Virtual Test, numerical accuracy needs to be validated with model test data in physical tank and full scale test data in real sea. However, the NWT, under systematical validation, has many incomparable advantages over physical tank, such as being efficient, time-saving, low-costing, being able to be controlled remotely, thus it reduces the uncertainty in designing and realize the optimization of design.

MARINTEC CHINA
 
MARINTEC CHINA is the largest maritime exhibition in Asia Pacific and the second largest one in the world. It is the bridge and bond for all members in the international maritime community to seek all-directional, multi-layers cooperation. After more than 30 years development, MARINTEC CHINA has grown to be strong enough that can fully demonstrate the size and importance of the Asian maritime market, and has become one of the most authoritative exhibitions in the world.
Sponsors
Harbin Engineering University (HEU), established in 1953, is the first university focused on developing Naval Architecture and Ocean Engineering. HEU is one of the most key research centers for cultivating talents in the field of Shipbuilding Industry, Marine Equipment and Exploration as well as talents in nuclear application. HEU initially set up ICNAME, International Innovation and Cooperation in Naval Architecture and Marine Engineering Alliance, Deep Sea Engineering and High Technology Marine Collaborative Innovation Center, Association of Naval Architecture and Ocean Engineering Universities Alliance.
 
Marine Design &Research Institute of China (MARIC), established in 1950, is the earliest research and development organization of a large scale and with many achievements in China State Shipbuilding Industry.
