Abstract
Batavia Coast Marina (BCM) in Geraldton, Midwest WA is one of 50 Department of Transport (DoT) coastal facilities spanning Western Australia from Wyndham to Esperance. Since construction of BCM was completed in 1995, there have been significant operability issues in the form of excessive motion of moored vessels, mooring line breakages, and damage to pens at the facility. The objective of the study is to investigate the causes of BCM operability issues including Gravity and IG wave penetration, transmission through the breakwater, and basin resonance. This is accomplished by a comprehensive 3-year data collection program of strategically placed instrumentation including 3 Acoustic Wave and Current (AWAC) devices, 6 pressure sensors, an Aquadopp, Waverider, vessel motions, and structural inspections.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/tOxTvx0pqns

The objective of the study is to investigate the causes of BCM operability issues including Gravity and IG wave penetration, transmission through the breakwater, and basin resonance
The datasets collected from multiple instruments have been analyzed and compared to empirical/analytical methods to investigate the relative contribution of each potential cause of the operability issues
Summary
OBJECTIVE The objective of the study is to investigate the causes of BCM operability issues including Gravity and IG wave penetration, transmission through the breakwater, and basin resonance. This is accomplished by a comprehensive 3-year data collection program of strategically placed instrumentation including 3 Acoustic Wave and Current (AWAC) devices, 6 pressure sensors, an Aquadopp, Waverider, vessel motions, and structural inspections. Results from IG wave modelling are assessed.
