The MDL Fanbeam® 4.2 and 5 Laser Rangefinders are industry-leading laser-based Position Reference Systems (PRS) designed to provide precise vessel positioning data for Dynamic Positioning (DP) operations in offshore and marine environments. Developed using advanced laser ranging technology, both systems deliver accurate range and bearing measurements to support vessel station keeping, offshore construction, subsea operations, drilling support, and renewable energy projects.
Advanced Laser Position Reference Systems for Dynamic Positioning and Offshore Marine Operations by SMTS Marine Solutions LLC
Overview of Fanbeam Laser Rangefinders
Fanbeam laser rangefinders are designed to provide an independent position reference source for Dynamic Positioning systems by measuring the vessel’s position relative to a fixed target or offshore structure.
Using laser pulse technology, the system continuously measures the distance and bearing to specially designed passive reflectors mounted on offshore platforms, wind turbines, vessels, or fixed marine structures. The measured data is processed and transmitted directly to the vessel’s DP system, enabling accurate thruster control and precise station keeping.
These systems are commonly used as an alternative or complementary reference to GNSS, DGPS, and other positioning technologies, providing additional redundancy and operational safety during critical offshore operations.
The technology operates by transmitting laser pulses toward passive reflectors mounted on offshore structures, platforms, vessels, wind turbines, or fixed marine installations.
How Fanbeam Laser Rangefinders Work
Laser Pulse Transmission
The system emits invisible laser pulses toward a passive reflector positioned on a fixed offshore structure or target.
Time-of-Flight Measurement
The return signal is analyzed to determine the exact travel time of the laser pulse, allowing the system to calculate the precise distance to the target.
Bearing Calculation
Using advanced optics and scanning technology, the system determines the relative bearing between the vessel and the target reflector.
Position Reference Output
The measured range and bearing information are transmitted directly to the vessel’s Dynamic Positioning system, providing real-time vessel position reference data.
