\section{Introduction}
-\section{Math}
+Simulation of ship motion in ocean waves is done in several computer
+programmes~\cite{matusiak2013,shin2003nonlinear,ueng2008} that differ in what
+physical phenomena they simulate (manoeuvring in waves, compartment flooding,
+regular and irregular waves, wind, real-time simulation or batch processing
+etc.) and application area (scientific studies, education or entertainment).
+These programmes are virtual analogues of ship model basins that are used to
+simulate characteristics and behaviour of ship in a particular sea conditions.
+The advantage of using virtual ship model basin over a physical one is that
+experiments are performed in real scale (with real-sized ships and ocean waves)
+and on a computer without the need to access high-technological facility.
+
+Although, all numerical experiments are performed on a computer, one computer
+is not powerful enough to perform them fast. Often, this problem is solved by
+using a cluster of computer nodes or a supercomputer; however, a supercomputer
+or a cluster is another high-technological facility that a researcher have to
+gain access to. In that case virtual ship model basin has little advantage over
+a physical one: the research is slowed down by official documents' approvals
+and time-sharing of computing resources.
+
+One way of removing this barrier is to use use graphical accelerator to
+speed-up computations. In that case simulation can be performed on a regular
+workstation that has a modest graphics card. This is one of the features that
+distinguishes Virtual testbed with respect to existing ship motion simulation
+programmes.
+
+\section{Virtual testbed}
+Virtual testbed is a computer programme that simulates ocean waves, ship motion
+and compartment flooding. One feature that distinguishes it with respect to
+existing proposals is real-time visualisation and the use of graphical
+accelerators for speeding up computations.
