Nonlinear wave force includes several frequency components, and may induce offshore structures collapse due to its resonance motion. In this talk a brief introduction will be given on the hydrodynamic research at DUT and numerical models developed at DUT for computing wave force and response of coastal and offshore structures. Both frequency-domain and time-domain numerical models have been developed based on the higher order BEM at DUT. The frequency-domain models are accurate to the second order of wave steepness, and can compute the action of bichromatic and bi-directional incident waves. In the frequency-domain analysis, a kind of new QTF’s was proposed for the simulation of nonlinear wave interaction with a floating body. The time-domain nonlinear wave force models were also developed, one is a Cummins model based on the new QTF’s and others are full-time domain wave tank models. All of these models are coupled with mooring line and riser models for the practical analysis of real offshore structures.

Prof. Bin Teng received his PhD from Dalian University of Technology, China in 1989, and was a post-doctoral research assistant in University of Oxford, United Kingdom from 1990-1992, a Japan Science and Technology Agency Fellow in Ship Research Institute, Japan from 1995 to1996, an academic visit in the University of Hong Kong in 2001. In 1996 he was promoted as a professor by Dalian University of Technology, China, and in 2001 became a specially appointed professor in the “Cheung Kong Scholar Program”. He works on hydrodynamics of coastal and offshore engineering, especially on the computation of wave loads, ship berthing in harbor, hydro-elastic response of very large structures, wave interaction with multiple bodies, and coupling analysis of deep water platforms with risers and mooring lines.
