Currently, studying the behavior of complex technical systems in extreme situations is actively used in real-time computer experiment. For the interpretation of the results involved virtual reality technologies allows researchers to "dive" in the modeled phenomenon with the ability to monitor it comprehensively and influence on it by the observer, including the training the observer to act in extreme conditions. The creation of such a problem-oriented software systems (virtual testbed VTB) requires the integration of mathematical models, software and hardware rendering tools, tools of human-computer interaction, and possibly the interfaces to the real object. One of the most promising consumer technology VTB is the industry associated with the design, construction and operation of ships, objects, ocean engineering and hydrotechnical structures. This need is due not only to the complication of marine objects by themselves, increasing their security requirements and competition in reducing design time, but the general trend of reducing the cost of physical prototyping and field testing. Advances in the development of virtual towing tank to perform simulations in different thematic objectives involved in the calculations of hydrodynamics and the strength of the offshore facilities, but the means of graphic representation of results and organization of the computational experiment (CE) in such cases is usually tightly integrated with specific software products. As a result, it limits the ability of CE in comparison of different methods and models to solve non-standard problems, and does not allow a virtual infrastructure model tanks to include new computational models of other manufacturers (as they become available). The article describes graphical toolkit, which implements the technology of VTBs applied to the problems of marine design providing effective mechanisms to overcome the above limitations. Creating of the VTBs for marine research and shipbuilding related to the solution of fundamental problems of technological nature. It uses a common approach to the creation of computer simulation systems. Approach is based on the concept iPSE (Intelligent Problem Solving Environment), and implemented through CLAVIRE platform. It covers the following aspects: the unification and ensuring the compatibility of various computational models, to provide the necessary performance VTB, automation scenario selection of the experiment, the use of advanced tools of human-machine interaction, and computational experiment broadcast on the Internet. Toolkit is focused onto development of the VTBs to study the dynamics of complex systems in a variety of subject areas and significantly simplifies the process of development of imaging solutions to the various categories (from the game and training systems to the application server and render services VaaS, VTB), which integrate a variety of computing, technical and information resources.
