We carried out a 1:50 scale 3D physical model tests of the MOF, including the breakwater, to confirm that the chosen layout provides the required level of shelter for marine operations and that the structures are robust enough to withstand cyclones. The model tests simulated a 1:200 year storm, under which the tugs are moored at their berths, and an overload condition that is close to a 1:1000 year storm under which the breakwater should remain largely intact
Within the 3D model testing we also assessed:
- wave run up and overtopping
- tug mooring arrangements including:
- tug restraint structures
- tug mooring line forces
- tug berth fender loads
- wave conditions at the MOF quay.
Due to the scale of the development, the breakwater construction occurred over the span of two cyclone seasons. For this reason a physical model of the partially built breakwater was also tested.
