River, coastal and shallow marine hydrographic surveys
River, coastal and shallow marine hydrographic surveys can be undertaken usinglocally hired shallow draft boats with our own personnel and equipment, including 3 No. echo sounders up to 100m depth capability, automatic digital tide monitoring equipment, DGPS positioning and navigation equipment.
All equipment fully calibrated.
Single & dual frequency echo sounders, CEEDUCER Pro.
Positioning & tracking using PSION navigation system with Hypack software
linked to real time DGPS Leica 1200 series base station , current meter and rover units and
TIDE MONITORING using CEETIDE.
Calculation of tide constants – mean sea level ( MSL ), Chart Datum ( CD ), Lowest Astronomical Tide ( LAT ), Highest Astronomical Tide ( HAT ) and other tide based parameters.
Typical projects have included:
Ports, harbours, berths & marine terminals.
Ship navigation channels
Coal & oil / gas loading & unloading facilities
Underwater Pipelines & cables
Position fixing for drilling & construction works
Feasibility, design & construction engineering works
River and coastal crossings – bridges, embankments, road,rail & pipeline / cable crossings.
