Results of the fluid-structure co-simulations that were carried out as part of the FleksProp project are presented. The FleksProp project aims to establish better design procedures that take into account the hydroelastic behavior of marine propellers and thrusters. Part of the project is...

Hyperbaric arc welding is a special application of joining the pipeline steels under seawater. In order to analyze the behavior of the arc under ambient pressure, a model is required to estimate the arc efficiency. A distributed point heat source model was employed. The simulated isotherms were...

Pipeline plays a very important role for transporting oil and gas from offshore fields to on-shore facilities. The recent trend of exploring oil and gas in deeper water exposes extreme challenges for pipeline laying as well as repair. For the sake of human health, the maximum depth of diver assisted...

Analytical and numerical approaches are used to model a gas metal arc welding (GMAW) process. In order to simulate the detailed aspects of material changes during the process, it is important to implement the correct size and distribution of the heat source. In this study the dimensions of a heat...
