1 DESCRIPTION 3

ULS1 = ULS cases where the wave is applied so that maximum quasi-static pontoon moment will occur with wave crest or wave bottom at pontoon middle point.

ULS2 = ULS cases where the wave is applied so that maximum quasi-static column moment will occur with wave crest or wave bottom at ¼ of the pontoon length and the corresponding opposite wave bottom or wave crest at ¾ of the pontoon length.

0-90 deg = angle of wave application, 0 degrees pointing at pontoon longitudinal axis.

The following sections show analysis results for all wave directions.

RELATERTE DOKUMENTER

Nevertheless, it is worth mentioning that even with the same setup of wave gauges in the numeric event, some of the numerical wave events experienced maximum crest eleva- tion at

With a speed limit of 12 knots, the wave periods of vessel generated waves will be so short that the wave energy of such events will be negligible compared to the wave energy

Bending moment of the pontoon itself is the main contribution to the stresses in the pontoon column interface, so the difference in column shear force of 22% or 1.3 MN (from 5.8 MN to

Five different wave inputs with varying wave height, wave period, and main direction are imposed at the offshore boundary of the numerical model.. The governing Laplace equation

We now have a validated numerical method for studying the pressure propagation, and other physical parameters, inside a human head exposed to a blast wave.. This could be useful

6) Simulations for some tested conditions and comparison of the wave frequency motion spectra with corresponding test results. Damping is added if needed. 7) Identification of

The wave generation and propagation of steep irregular waves in the numerical model is validated by comparing the numerical wave spectrum with the experimental input wave spectrum..
