1 INTRODUCTION Fluid flow predictions for ships and marine structures are often significantly more complex

Fluid flow predictions for ships and marine structures are often significantly more complex
than those for other vehicles. Sailing on a random free surface and undergoing large unsteady
dynamic motions poses a significant number of extra requirements to the methods applied. In
the past, researchers have developed numerous, dedicated computational methods having par-
ticular applications in mind. Although these methods are extremely useful tools in their own
right, the majority of them lack the level of accuracy which would allow the replacement of tra-
ditional model testing, which is still the measure to compare with. The large variety of numeri-
cal methods developed for dedicated applications poses another problem when targeting an in-
tegrated approach to ship simulation and optimisation during design. Different requirements,
numerical approaches and implementation issues often do not allow for easy exchange of data
and hence for the interplay of numerical methods and the collaboration of partner design teams,
the latter amplified by the fact that use of most of these tools are laborious and time consuming.
Moreover, today's requirements for life cycle considerations during product design are pro-
gressively a necessity. This calls in turn for a more integrated product development and design
approach covering all pertinent aspects of ship hydrodynamic behaviour. Therefore, in order to
maintain its competitive edge, the European Shipbuilding industry must be supplied with accu-
rate, fast and integrated analysis tools, applicable over the full duration of the ship design proc-
ess and capable of covering all relevant aspects of hydrodynamic design analysis in a holistic
manner. To meet this need a software platform, the VIRTUE Integration Platform (VIP), is be-
