Marine/Offshore

Marine and offshore projects always have to do with complex fluid dynamics. Computational Fluid Dynamics is a digital towing tank without limits. It’s faster, more accurate and the results output provides much more detail. We can support you with basic hull performance analyses (towing power) up to dynamic water-object interactions. CFD is also a very important tool when designing an offshore project like a wind turbine plant or oil rig.

Dynamic Motion Response

In this example we have studied the dynamic motion of a crane vessel in shallow water. The main objective of the study was to indicate the pressure on the keel by the seabed for several regular wave periods. The study was carried out in combination with ORCA offshore (http://www.orca-offshore.com) and Naval Dynamics (http://www.navaldynamics.com).

Evacuation study Stad Amsterdam

The Stad Amsterdam is a passenger sailing vessel offering corporate events, adventurous sailing cruises and luxurious cruises towards many different destinations.

The objective of the evacuation simulations was to calculate the evacuation time of the current proposed evacuation route arrangement from the Longroom to the assembly station and compare the obtained time with a fictive arrangement using SOLAS compliant stairs and doors. The current evacuation route arrangement is considered to be acceptable in case that the obtained Required Safe Evacuation Time (RSET) of the current arrangement is shorter than the RSET of the fictive SOLAS compliant arrangement.

The study and result have been approved by the USCG (United States Coast Guard).

Digital Towing Tank

CFD (Computational Fluid Dynamics) is the alternative solution for a towing tank. This advanced computer technique enables designers to make quick comparison between hull designs. Increment studies can show the optimal cruise velocity of the ship. Detailed flow patterns provide in depth information on how to optimize the hull for the specific performance criteria. Basic analyses include: Wave pattern, friction drag, wave drag, total drag, towing power, propeller inflow and the flow pattern along the hull. More advanced features can be analysed like front wave encounter, side waves, propeller hull interaction, green water on deck etc.

MonoBase Lowering Simulation

This simulation shows the free fall of a 6,000 ton base section of the MonoBase wind turbine foundation. The calculation confirms the expected de-acceleration when approaching the seabed and a smooth and soft landing. Read more at http://www.monobasewind.com/Engineering
