Ocean 3 Donut Fenders will provide a high Energy absorption for a low reaction force as with other foam filled fendering systems. It also has the ability to rotate around a steel monopile where large tidal changes occur with no high shear forces, by the mean of internal anti-friction UHMW bearing pads, even under compression;  it gives the capability of changing the direction of Energy with no need to absorb all of it, just as a pulley.
