..., simulation of the escort capabilities in different operational scenario, and development of control logics that will allow autonomous or unmanned operations. The tug design concept is supported by a customized simulation tool that enables the evaluation of the free-sailing and towing maneuvering...

... operational windows, ROV simulators can be used. Since the ROV tether, which provides power and telemetry, will at times dominate the ROV motion, the tether must be accurately modeled over the full duration of a simulated ROV maneuver. One aspect of the tether dynamics that remains relatively untouched...

.... During our development of this method, we undertook as a benchmark case the simulation of bore propagation in shallow water and up onto beaches, a classical problem in hydraulics. One reason for this was that the bore is a breaking wavefront whose strength and severity may be increased simply...

... very studied due to the complexity of the phenomenon. The authors have studied the models of several researchers and three of them were picked up and implemented in the DYNASIM, a moored ship dynamic simulator. These models will be discussed and compared. In deep water, the total length of the mooring...

Tavassoli A finite-difference scheme and a modified marker-and-cell (MAC) method are used for numerical wave tank (NWT) simulations to investigate the characteristics of nonlinear multidirectional waves. The Navier-Stokes (NS...

...T. E. Schellin; C. Schiff; C. O¨stergaard A nine-degree-of-freedom time domain mathematical model was used to numerically simulate crane ship dynamics. This model considers the elasticity and damping of the hoisting rope assembly and includes arbitrary, biangular swing of the suspended hook load...

...T. H. Dawson Applicability of extreme-value theory in predicting the maximum crest amplitude in runs of ocean waves is demonstrated using data from extensive computer simulations of random linear waves. Extension of the theory to include wave crests in heavy seas is also made within the context...
