报告题目1:Safety assessments of ship enduring behavior under tsunami attacks


报告人:小林英一 教授 (日本神户大学海事科学研究科)

摘要:Numerous large scale earthquakes have occurred along the Nankai Trough in the Pacific Ocean off Japan. The estimated possibility of large earthquake that can also generate tsunami is at the Toukai, Tounankai, and Nankai coastal regions is 70% over the next 30 years. A tsunami hitting the bay area raises the sea level and causes strong horizontal flows. Most ships in the bay and port areas are subject to these flows and therefore may be forced to move. Such phenomena can make a ship’s movement uncontrollable, slam it into breakwaters, and set it adrift or ground it. Furthermore, they can subject piers to tremendous forces. Therefore, it is very important to understand these phenomena and the resulting ship movement and to consider possible counter measures such as evacuation to a safe distance from the coastline as well as maneuvering, anchoring, and strong mooring. It is particularly urgent to uate the effects of a tsunami on ships such as small ships that are moored at the pier because they may affect more serious damage to the structures along the coast, passenger ships, and VLCCs carrying hazardous materials. This presentation shows some basic analyses of ship motions under a tsunami attack and possible countermeasures as mooring, anchoring, and evacuation maneuvering.

摘要:Particle methods have good capability for the analysis of highly nonlinear free-surface flows, so they are often applied to the safety assessment of ships and marine structures at sea. In particular, deck wetness in rough seas, flooding into damaged compartment, sloshing in LNG tanks and green-water impact to marine structures are major applications, which are difficult to be handled by existing analytical methods. In this lecture, examples of these latest applications are introduced and the current situation of large-scale particle-based simulation is mentioned for the application to realistic problems.
