Floating Wharf Breakwater
Town of Penetanguishene
Riggs Engineering was engaged by Harbour West Marina Inc. to provide a design for a T-shaped floating dock replacement. The design components included:
- Extensive finite element analysis of the floating dock, floating breakwater and aluminum gangway.
- The dead and live load forces and reactions, including structural steel and timber superstructure, were modelled to determine various design conditions.
- The T-dock floats’ design consisted of quadruple and single steel pipe flotation units which were modelled as shell elements. Typically each float module is 17.5 m long by 7.3 m wide.
- The floating breakwater design is generally a typical float module attached with a wave attenuator to provide protection/shelter to recreational vessels.
- The 15 m long by 2.4 m wide gangway leading to the floats was designed with aluminum and timber decking to minimize loads on floating docks.
- The T-shaped floating dock is primarily designed for high berthage capacity for public use or gatherings/festivals.
