Evaluation of hydrodynamic wave pressure on large-scale structure is an important task in the wave load design of thin-walled components used in sea-crossing bridge. This study focuses on the probability distribution of hydrodynamic wave pressure on a large-scale thin-walled structure using on-site measurement data. An in-situ observation project is conducted to collect the wave elevation and the wave pressure on a rectangle cofferdam during a tropical cyclone event. With the measured data, the wave conditions and the fluctuating wave pressure are extracted, and the corresponding statistical characteristics such as the cumulative density function (CDF) are derived. In addition, a time domain boundary element model (TDBEM) is introduced to provide the statistical comparison. Several wave conditions derived by the statistical wave indicators during the cyclone event are fed to the numerical model for pressure investigation. Based on the statistical indicators and the modeling results, the comparison of wave pressure spatial distribution between TDBEM and the on-site measurement is presented. The pressure probability distribution is presented to further reveal the differences on the statistical characteristics. The resultant bias mainly occurs in the low-exceeding-probability range on the up-wave side and the high-exceeding-probability range on the down-wave side.

“…Compared to the first one, the Rankine source method removes the explicit memory effect from the integral equation. Typical works of this method are finished by Isaacson and Cheung [15,16] calculating the second-order wave loads on a single cylinder. Nevertheless, the solution requires truncating the fluid field at some finite distance.…”

“…A lot of researches have been done on the time-domain problems. Using the Boundary Element Method (BEM) [1][2][3][4][5] , BAI and TENG [6] have solved the linear and second order wave radiation and diffraction problem. WANG and WU [7] , using the Finite Element Method (FEM), have done fully nonlinear and second-order wave-body interaction problems.…”

Direct time-domain simulation of floating structures has advantages: it can calculate wave pressure fields and forces directly; and it is useful for coupled analysis of floating structures with a mooring system. A time-domain boundary integral equation method is presented to simulate three-dimensional water wave radiation problems. A stable form of the integration free-surface boundary condition (IFBC) is used to update velocity potentials on the free surface. A multi-transmitting formula (MTF) method with an artificial speed is introduced to the artificial radiation boundary (ARB). The method was applied to simulate a semi-spherical liquefied natural gas (LNG) carrier and a semi-submersible undergoing specified harmonic motion. Numerical parameters such as the form of the ARB, and the time and space discretization related to this method are discussed. It was found that a good agreement can be obtained when artificial speed is between 0.6 and 1.6 times the phase velocity of water waves in the MTF method. A simulation can be done for a long period of time by this method without problems of instability, and the method is also accurate and computationally efficient.
