Modified XC-2 systemfor deep marine application

JAN DE NUL

• One of our biggest costumers is the dredging company JAN DE NUL.

• They where one the main contractors for the PALM ISLAND in DUBAI.

Collaboration between Leica JAN DE NUL

• To be able to do this project in an efficient way, we could convince them to use the MIKRODIGGER system.

• The MIKRODIGGER was linked to a 3D unit.• We did some test in belgium and they where

very happy with the result.

Problems we faced

• Due to the very salty water and the high temperatures the connectors of the sensors and even the sensors it selves corroded away in a few weeks time.

• Therefore we had to come up with a housing where we could mount the sensor in and witch was resistant to the environment in Dubai

The solution

• So we have an RVS housing that gives great mechanical protection and that is water tight.

• We also looked for the best connectors that are water tight up to 700m depth.

• We created 2 models: – One for the bucket sensor – One for the stick sensor

The 2 versions

The bucket version The stick version

Some pictures of installations

New application

• Recently JAN DE NUL has developed or modified an excavator so it can be controlled by remote control and that is submerged completely till up to 30m.
