General information
MARIN has been working on the use of CFD for manoeuvring applications since 2004. Generally, CFD is used in the same way as PMM experiments, i.e. to obtain the forces and moments on the hull as a function of the manoeuvring motion. This technique is sometimes called Virtual Captive Test. The results of the CFD calculations can then be used in fast-time simulation programs (such as SurSim, see here) or our full-mission bridge simulator to simulate all kinds of desired manoeuvres. This capability leads to a considerable improvement in manoeuvring predictions compared to predictions based on empirical formulae alone.

Apart from predicting the forces on ships, CFD is also used to study the flow around ships in manoeuvring motion. With this information, possibilities for design improvements can be derived.

Portfolio
During the years, CFD has been used to compute the forces and moments on a wide variety of ships, comprising new designs within commercial projects, but also well known benchmark cases such as the KCS, KVLCC1, KVLCC2(M), Hamburg Test Case (HTC) and the DARPA SUBOFF submarine.

Verification and Validation
To ensure the quality of our work, regular verification and validation studies are performed. In the figure on the left, an example validation result is given for the transverse force Y on the HTC at various drift angles. The possibility of using CFD, in this case ReFRESCO, for predicting the forces on manoeuvring ships even up to large drift angles is clearly demonstrated.



The work on CFD for Manoeuvring Application has resulted in the following PhD thesis, which includes ample verification and validation studies for benchmark test cases:
