I have a query about the static equilibrium test. I was of the opinion that it is carried out to ensure that a floating platform weight is balanced with the buoyancy forces and so, a mean heave of zero is what one is looking to obtain. I think I remember you had said that the DeepCwind was set up so that it produces mean heave of zero for a static load test.
I am trying to verify a FOWT model and thought that the aim of all static load test was to tune the platform such that a mean heave of zero is produced. Thus confirming a balance between the weight and the buoyancy forces.
