Kongsberg Seatex, a Norway-based firm that produces dynamic positioning, navigation and automation systems for merchant vessels and offshore installations, has introduced a new laser-based reference system, SpotTrack, for use in offshore applications.
Intended for Dynamic Positioning (DP) operations, the lightweight SpotTrack is a motion stabilised rotating laser sensor that delivers range and bearing measurements for single or multiple retro-reflective targets.
To track multiple targets, SpotTrack uses an advanced detection system and tracking algorithm.
It is built on DP reference system technology and is used mainly in conjunction with satellite positioning, microwave-based systems and subsea positioning.
SpotTrack can also track targets at high elevation angles by using roll and pitch stabilisation from a motion reference unit, which makes it ideal for 3D positioning during maritime construction.
Kongsberg Seatex AS sales and customer support vice president Vidar Bjørkedal said laser-based reference systems represent an established technology, but SpotTrack introduces a new level of reliability and ease of operation.
"The sensor itself is a completely sealed unit, with all moving parts housed inside, so the system is less prone to mechanical wear from exposure to the elements," Bjørkedal added.
"By this approach we have created a more durable product, well adapted to the requirements of critical operations, and with the benefit of less costly maintenance."
Kongsberg Seatex president Gard Ueland said, "With the addition of SpotTrack to our extensive reference systems portfolio, Kongsberg Dynamic Positioning customers now have the choice of a complete range of above-surface and subsea reference systems developed by Kongsberg."
In addition to DP operations, SpotTrack can also perform automatic docking systems and vessel traffic monitoring activities.
