Ship loader collisions that threaten personnel, damage valuable assets or limit operational availability can be avoided.
MRA’s Ship Loader to Vessel ACS (Anti-Collision System) and add-on modules are a complete ship loader protection system that provides tools to assist loading, protect the safety of personnel and help eliminate accidents impacting operational continuity.
The ACS builds a highly accurate, 3D map of the vessel via millions of data points collected from scanners installed on the ship loader. The scanners are relatively low-cost, long-life LiDAR suited to the harsh environmental conditions typical to ship loader operations.
Collision Detection and Inhibit
The ACS establishes a real-time protection zone surrounding the ship loader’s boom and shuttle, its spout / spoon and operator cabin. The improved visibility eliminates blind spots. Any object entering or nearing these dynamically defined zones will trigger a collision or inhibit unsafe movement.
Key separation distances for the ship loader are available to the PLC for actioning including, alarm, slow down and inhibit. I.e. all control resides in the existing machine PLC.
Vessel Loading Balance Detection
Vessel Loading Balance Detection is an ACS add-on module that tracks vessel list, trim and draft, and the position along the wharf during loading are tracked in real-time. The operator can use this information to adjust the loading pattern, to ensure the vessel is “upright” prior to completion. This module also reduces the face to face contact between port and operational staff and crew members.
Vessel Drift Detection
Vessel Drift Detection monitors for unexpected vessel movement, such as drift due to a broken or loose mooring line. Early warning enables the operator to respond in a safe and timely manner. With the addition of berth mounted scanners, this detection can be performed any time.
The Hatch detection module is an operator support tool that uses advanced object identification to determine hatch state – open/closed; hatch dimensions; hatch edge identification; and, deck gear. This information can be used to by the PLC to ensure the ship loader is located at the correct hatch for loading.
- Reduce personnel safety incidents
- Provide improved visibility for operators, minimising blind spots from cabin / CCTV systems.
- Increase site efficiency
- Eliminate ship loader accidents
- Ensure continued operations
- Uses relatively low-cost, long-life lasers that require minimal maintenance.
- Our off-site simulation environment allows for custom set up for each machine geometry, increasing accuracy and lowering the cost of setup and commissioning.
Control aspects all performed in the PLC
- Zero collision incidents in more than 100 months of active operations.
