Improving dredging operations for underwater applications

For the benefit of its customers in offshore applications, Leica Geosystems has introduced its Leica MSS420 Dredging Sensor. VG Entreprenør, a construction company with expertise in all types of coastal area projects, started working on a project for the extension Esbjerg port, Denmark, with a new urban area and marina using the new sensor.

“Working in a harsh environment combined with extreme weather conditions can be a challenge for the project. The Leica MSS420 sensor helps us keep the machines up and running under a tight schedule for the planned operations,” said Claus Agger Sørensen, Project Manager at VG Entreprenør A/S.

Resilience and flexibility
Reinforced components such as special water tight connectors, rugged cabling, robust sensor housing and stainless-steel brackets make the sensor usable down to 40m at 4 bar pressure. In addition, the MSS420 sensor can be programmed to boom 1, boom 2, stick, bucket and even tilt sensor. This makes the changing of sensors simple, even for less experienced operators on the construction site.

High precision attainable at any speed
Inertial measurement technology incorporated in the sensors and combined with gyroscopes and accelerometers offers responsive sensor technology that improves digging accuracy and increases the operator’s overall speed in completing the work. The solution enhances performance, reduces costly rework and increases up-time during poor GNSS coverage.

“The Leica MSS420 sensors have been designed with marine applications and harsh environments in mind. The extremely robust components made of stainless-steel guarantee reliable and precise dredging jobs under water,” said Marcus Grevelshoej, Product Specialist for excavating solutions at Leica Geosystems.
