The use of developable surfaces in ship design is of engineering importance because they can be easily manufactured without stretching or tearing, or without the use of heat treatment. In some cases, a ship hull can be entirely designed with the use of developable surfaces. In this paper, a method to create a quasi-developable B-spline surface between two limit curves is presented. The centreli...

With the increase of ship size, stiffness hull structure becomes smaller. This means that frequency wave excitation tends to be closer natural vibration, which in turn makes hydroelastic responses more significant. An accurate assessment loads and motion hulls is key design safety assessment. In this paper, coupled CFD (Computational Fluid Dynamics)-FEM (Finite Element Method) method used inves...

This paper describes three ultrasonic inventions linked by the means to remove biofilms, and so prevent problems of societal importance. The first is cleans flat surfaces, or surfaces with long radii curvatures (e.g. ship hulls). Macroscopic marine biofouling takes hold following development a bacterial biofilm on hull. device inhibits maturation biofilm, reducing establishment macroscopic biof...
