The VCT method is taking us forward
Manoeuvring performance generally features too late in the design process in SSPA’s experience. Sometimes shipyards have to face costly and time-consuming last-minute changes to the design (when the IMO standards for ship manoeuvrability are not met). And what if the manoeuvring performance is “too good”? Is the rudder too big? (Resulting in resistance that is too high). The use of a new method of CFD calculations enables SSPA to offer early-stage manoeuvring predictions with much higher accuracy than before.
By sorting out the manoeuvring issues before too much time has been spent optimising the hull lines, the newbuild project will save time and money in the design stage. SSPA’s experts also believe that this approach will lead to safer, better and more sustainable ship design. Virtual Captive Tests (VCT) is one of SSPA’s “manoeuvring tools”.

Tools for investigating manoeuvring performance
Running model tests will avoid the risk of very unpleasant surprises during full-scale sea trials. The manoeuvring model tests are usually performed late in the design process. If the requirements are not fulfilled at this time, undesired design changes may be needed at the very end of a project. SSPA’s “manoeuvring tools” can fit the design spiral for new-build merchant ships and thus avoid costly last-minute changes.
