3103F.6.5 Configuration Coefficient (CC)
This factor accounts for the difference between an open pier or wharf and a solid pier or wharf. In the first case, the movements of the water surrounding the berthing vessel is not (or is hardly) affected by the berth. In the second case, the water between the berthing vessel and the structure introduces a cushion effect that represents an extra force on the vessel away from the berth and reduces the energy to be absorbed by the fender system.
For open berth and corners of solid piers, Cc = 1.0
For solid piers with parallel approach, Cc = 0.8
For berths with different conditions, Cc may be interpolated between these values [3.19].
