Operability Investigation of a Midwest Western Australian Marina Subjected to Gravity, Infragravity, and Transmitted Waves

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
