FANBEAM 4.2 – SCANNER HEADS

Description

MDL’s Fanbeam® system is a laser based positioning sensor designed for repetitive, high accuracy range and bearing measurements from offshore support vessels and other marine structures.

The system is primarily used as a dynamic positioning (DP) reference sensor measuring the position of an offshore support vessel (OSV) relative to an offshore structure such as a platform. Using the position data from the Fanbeam and other sensors, the DP system automatically holds the vessel on station allowing operations to take place. The system is regularly used as the primary position reference during critical short-range operations such as cargo container lifts from platform supply vessels.
The system has also been extensively used for seismic source positioning relative to geophysical exploration vessels and for positioning mine detection equipment relative to navy vessels.

The system is in use on all types of different OSV’s including:
• Crew Supply Vessels
• Platform Supply Vessels
• Anchor Handling Tug Supply Vessels
• Construction Support Vessels
• Multi-Purpose Support Vessels
• Dive Support Vessels
• Dredging & Rock Dumping Vessels
• Well Stimulation Vessels
• Heavy Lift Construction Semi-Subs
• Accommodation Flotels

System Advantages:

• Performs excellently during short range or long-range operations.
• Achieves high accuracy consistently
• Utilises inexpensive intrinsically safe targets that can be permanently installed onto many offshore installations
• Rugged design
• Long product life
• Valuable alternative or compliment to DGPS and other position sensors
• Simple operation and setup
