Study on Second-order Wave Exciting Forces on Cone Shaped Floating Bodies

Time-domain analysis of wave exciting forces on floating bodies at zero forward speed

The problem of determining the exciting forces acting on a rigid floating body due to uni-directional waves has been extensively studied. The problem is usually formulated in the frequency domain by assuming that the incident waves are sinusoidal of fixed frequency. Results for more general wave systems may then be found using superposition and Fourier analysis. In this paper, the problem will ...

Wave drag on floating bodies.

We measure the deceleration of liquid nitrogen drops floating at the surface of a liquid bath. On water, the friction force is found to be about 10 to 100 times larger than on a solid substrate, which is shown to arise from wave resistance. We investigate the influence of the bath viscosity and show that the dissipation decreases as the viscosity is increased, owing to wave damping. The measure...

DEVELOPING A FORMULA TO REPRESENT THE SECOND-ORDER WAVE EFFECTS ON MOORED FLOATING STRUCTURES

The effects of wave direction, frequency and the waterline shape of floating structures on the wave mean drift force formula have been considered separately by several authors but there isn't a general formula to take into account all of these effects. In this regard, Faltinsen’s wave drift force formula has been modified by adding finite draft coefficient. The results obtained from this formu...

Effects of Second-Order Hydrodynamic Forces on Floating Offshore Wind Turbines

Second-order cone programming

Second-order cone programming (SOCP) problems are convex optimization problems in which a linear function is minimized over the intersection of an affine linear manifold with the Cartesian product of second-order (Lorentz) cones. Linear programs, convex quadratic programs and quadratically constrained convex quadratic programs can all be formulated as SOCP problems, as can many other problems t...
