Air Draft Clearance Project at Melbourne
Ensuring safe navigation under bridges requires precise measurements of three critical factors: Air Gap, Air Draft, and Air Draft Clearance. The Air Draft is the height of a vessel measured from the waterline to its highest point, while the Air Gap is the vertical distance between the underside of the bridge and the waterline. The Air Draft Clearance is the difference between the Air Gap and the vessel’s Air Draft, determining whether the ship can safely pass under the bridge.
Over the past year, OMC International has collaborated closely with Ports Victoria on a ground-breaking project to enhance safety for vessels transiting the Yarra River. This initiative introduces 3D LiDAR technology to measure the air draft of vessels in real time as they approach the West Gate Bridge. The system provides precise, instant air draft measurements to Melbourne VTS, adding a vital layer of safety to ensure vessels can navigate beneath the bridge. While LiDAR technology has been used in other industries, this marks an Australian first for its application in the maritime sector for air draft clearance.
This year, key milestones were achieved:
- Hardware installations at Breakwater Pier and South Wharf.
- Completion of system validation, with findings presented to Ports Victoria.
The BridgeClear system is a testament to the dedication of our team and Ports Victoria’s commitment to innovation. Together, we are setting new standards for maritime safety in Melbourne, with the system set to go live in 2025.
