MDL's Fanbeam 4.2 is a laser radar system
designed for repetitive, high accuracy
positioning and tracking of marine vessels, and
static and semi-static anchored structures.
The system is primarily used to control or assist
automatic docking of a vessel next to a platform,
jetty or other vessel. Traditionally, three sensors
are employed onboard a vessel involved in
dynamic positioning operations. MDL's
Fanbeam®4.2 compliments differential GPS
(DGPS) and can assume a primary role when
differential signals are lost or become
The system is also widely used to
position seismic vessels gun array floats as the
vessel surveys the latest oilfield prospects.
MDL's Fanbeam®4.2 system has many advantages.
Our customers tell us that the Fanbeam®4.2 is
straight-forward to set up, performs excellently during short range operations, high accuracy is
achieved consistently, the system utilises intrinsically safe targets, requires very little maintenance
and is low cost compared to other systems.
This versatile laser system can be employed as a
primary or backup system and is considered a valuable alternative or complementary system to
DGPS and other navigational aids
