 STEPFLOAT 
 

PURPOSE
Provide an alternative engineering solution mainly for shore protection and coastal shelter in a more environmentally-friendly manner

           

 

CONCEPT

Provides the required level of tranquility in an area it is desired to protect by intercepting and dissipating (rather than reflecting) the incident wave energy through the formation of wave  breaking, turbulence, vortices and frictional dissipation

 

Step - Multi-purpose Breakwater Facility

The STEPFLOAT breakwater system provides the following advantages :

Modular structure

Local design
   - removable & flexible Good materials
Multi-purpose functions    - heat resistant
   - wave attenuator   - weather resistant & strong
   - walkway    - non-toxic
   - marine habitats  Anti-UV compounds
Relatively less expensive Environmentally and ecological
Shorter construction period   friendly
Adaptable to water level change Safe habitat for fish & marine life
Aesthetics provided

Model Testing @ UTM Laboratory

The principal scope in the model study of the stepped floats is to investigate the wave height changes due to the wave-structure interaction. Experiments were conducted in the Hydraulics Laboratory of the Coastal and Offshore Engineering Institute, Universiti Teknology Malaysia, Kuala Lumpur on multiple rows of stepped floats. The laboratory investigations were conducted in a simplified environment and controlled condition where tides and currents were not taken into account. The experiments were run in the wave only condition in the wave flume which were subjected to steady monochromatic non-breaking waves throughout the experiments. In this study, variation in amplitudes of wave which were required for the respective analysis of energy dissipation due to the presence of the breakwater at different wave periods, incoming wave heights and dirrerent water depths, was determined.

EFFICIENCY COMPARISON OF THE STEPFLOAT vs OTHER FLOATING BREAKWATERS

 

 

STEPFLOAT has excellent wave attenuation ability over most of the other floating breakwaters found in the literature. it was found to be an effective breakwater in attenuating incident waves up to 80% and structurally  stable due to wave-structure interaction.
