iSAM utilized its existing and well-proven autonomous control system for grab ship-unloaders (GSUs) and combined it with its 3D model used for shiploaders. From a geometric standpoint, a shiploader and pneumatic unloader are very similar, which is why this approach significantly reduced development costs and time to market.
All these systems require a combination of the latest 3D LiDAR technology originating in self-driving cars, highly accurate RTK GPS systems for machine positioning, and internally developed leading-edge control technology including sophisticated filtering algorithms allowing the use of LiDAR in reduced visibility conditions.
The highlights of the iSAM solution
Operation
All devices are operated from a central control station, i.e. minimal workload for the operator in the control station: true full automation instead of remote control.
Real-time determination
of the suction nozzle position and all other machine movements
Autonomous unloading
even under the hatch coaming ("directed digging") or with "floor sweeping" for unloading down to the bottom of the hatch
Continuous updating
of hatch material mapping data for optimum control of suction nozzle
The advantages of the system
Significant reduction in personnel costs through driverless operation under virtually any weather conditions
Very consistent unloading performance
Lower wear and tear because mechanical performance limits are respected in automated mode
Compliance with operational guidelines and safety rules
No collisions of the suction nozzle or pipe with the ship due to integration of 3D Ship Model
Improved
working conditions thanks to supervision from central control room
