dc.description.abstractThe Master s thesis discusses verification of equipment transport on offshore platforms. The goal of the thesis is to use the form finding method dynamic relaxation to create a software application, which helps the layout engineers to automatically check whether an equipment transport route on offshore platforms is feasible using dynamic relaxation. This could potentially save a lot of time and add value by enabling the ability to run several iterations of the transport route with little effort. The thesis presents a new workflow, based on using the new application, and discusses advantages and disadvantages between the new and current workflow for transport route verification. By using Autodesk Navisworks and its .NET and COM API, a plug-in application was created for Navisworks, to automatically verify movement of an object through a given access way. This was done using Navisworks clash detective feature through the .NET API. The plug-in application required input parameter such as a validation object, a boundary geometry and a path. The plug-in application is divided into two phases; one path optimizing phase, and one verification phase. The optimizing phase is a pre-phase for the verification phase, to optimize run-time speed. The verification phase uses dynamic relaxation to try to move the validation object through the given path. If the validation object clashes with the boundary geometry, the dynamic relaxation will try to find a point of equilibrium where there is no clash. The plug-in application uses WPF (Windows Presentation Foundation) as a presentation system in .NET, with the MVVM (Model-View-ViewModel) architecture. The visualization of the validation object s movement, and the verification result, is done via Navisworks .NET API, where the movement is presented in Navisworks own UI. The plug-in application s UI will present information about the status of a verification. The UI gives the opportunity for the user to monitor the velocity, acceleration and applied force in the dynamic relaxation method during verification using chart controls.
