The LaseBCP Boom Collision Prevention is a two-dimensional laser measurement system that monitors the area around the boom of STS cranes during crane travel. If an obstacle on the vessel such as the bridge, radio antennas, etc. is detected during crane travel, a signal is sent to the crane control system to slow down or stop the crane travel before a collision with the vessel's superstructure can occur. The system is specially designed for use in STS ship operations and prevents significant damage, crane downtime and particularly dangerous accidents.
