NEREUS – I
Underwater Burial Tool
Nereus – I is an underwater burial tool, capable of operating successfully in shallow water
areas, without the need of additional propulsion since it moves forward as water comes out
from the cutting tools.
Nereus – I is supported by a floating platform or diving support vessel able to carry the water
pump, operators and diving equipment.
Nereus – I can be easily dismantled and containerized for transportation worldwide in short
notice.

NEREUS – I
Telemetry System
The innovative Nereus – I telemetry system consists of the following items:
-
Inclinometer
100m inclinometer cable
GPS device
Wireless GPS data communication system
Data analyzing software
Description:
The inclinometer is mounted on the cutting tool of the Nereus – I and it is calibrated
on the surface. As the cutting tool lowers, the angle of the inclinometer increases.
The data are received and analyzed from the software to calculate the actual burial
depth of the cable/pipeline acquired.
The GPS device is attached to the Nereus – I and provides positioning data of the
trench. The data are received through a wireless communication system from the
software.
The combination of the positioning data with the burial depth data, gives a detailed
mapping of the trench and burial depths achieved during burial operations. This
allows of real time monitoring of the process and archiving the data acquired.
