In this paper, a study on the principal performance of the purse seiner ship in two vessel formations was conducted. For this task, the outline of the purse seiner fishing system in two vessel formations was reviewed. At ...

A 30ft class aluminum leisure boat is newly developed and the resistance performances are investigated by a model test at a highspeed circulating water channel. The effect of a fin attached to the side of the hull is studied ...

In this study, we performed a three-dimensional (3D) topology optimization of a fixed offshore structure to enhance its structural stiffness. The proposed topology optimization is based on the solid isotropic material with ...

Using a 3-D numerical scheme (LES-WASS-3D) that considered wave-structure-sandy seabed interactions in a 3-D wave field, weanalyzed the wave reflection and hydraulic characteristics inside a slit caisson with two chambers ...

Because of the high stress concentration near the toe of a welded joint, the calculation of local stress using the finite element methodwhich is relevant to the fatigue strength of the weld toe crack, is a challenging task. ...

In this paper, a new generation method for ship induced waves is proposed using the fully non-linear 3-D numerical model with non-reflected wave generation system (LES-WASS-3D). A ship induced wave generated by the newly ...

Recently, as large structures, which should support large design loads have been constructed, the study on the large diameter composite pile becomes necessary. The large diameter composite pile has the diameter over 700mm ...

Accidental events such as collisions, groundings, and hydrocarbon explosions in marine structures can cause catastrophic damage. Thus, it is extremely important to predict the extent of such damage, which determines the ...
