This method is applied to a tidal energy platform designed by Bluewater Energy Services B.V., showing the sensitivity of this platform’s dynamic stability during ballast operations to tidal current velocity, changes in lightship centre of gravity and changes in the rate of ballasting. The developed method includes dynamic effects, tidal currents and mooring lines. Part of the developed method is a numeric model, written in the MATLAB environment, that simulates the platform motions, in 6 DOF, in time, during ballast operations. The model allows for large amplitude translations and rotations and for a changing mass and waterline area in time. Gravity, buoyancy, mooring line forces and tidal current lift and drag forces are taken into account. The model is analytically verified.
