Hydrographic & Offshore Surveys

Surveying in all waters

Accurate surveys of the seabed are vital before any infrastructure can be installed in the development of quarries, ponds, lake, river and maritime projects such as , Boat anchorage, baths, bridges, offshore wind farms, cable laying and pipeline installation e.t.c

Our survey team brings the latest hydrographic survey techniques to provide single beam, multibeam, side scan and sub-bottom survey services in different marine environments

MODERN TECHNOLOGY IN HYDROGRAPHY

Metricon provides hydrographic and bathymetric survey supporting the construction of offshore facilities like pier facilities, marine structural works, land reclamation, piling, marine structures maintenance ,technical support and rehabilitation, survey services for location, setting out and construction of marine structures and foundations, oil terminals, marine site improvement, refineries and storage facilities, as well as in geotechnical and geophysical soil investigations.

HYDROGRAPHIC AND MARINE SURVEYS

Our team range of hydrographic survey surveys ranging from horizontal and vertical survey control points along areas to be surveyed. We provide topographic surveys of the ground surface down to the water level. Hydrographic or Bathymetric Surveys allow effective design of infrastructure along the water front and off-sea infrastructure constructions.

Our hydrographic capacity includes vessels equipped with the latest multibeam, sector scan and single beam echo sounders, on-board processing and data displays, real-time centimetre level GPS position fixing, current metering ,side-scan sonar and magnetometers.

Bathymetric surveys allow surveyors and hydrographers measure the depth of a water body and map the underwater features of a water body. Multiple methods can be used for bathymetric surveys including multi-beam and single-beam surveys, sub-bottom profilers, and the Ecomapper Autonomous Underwater Vehicles.

Bathymetric surveys are used in various fields including port harbour dredging and monitoring, contour of streams and reservoirs, leakage, water-quality studies, dam removal, biological spill, storage and fill

Metricon offers Hydrographic Survey services tailored to provide professional hydrographic data and solutions to coastal engineering projects.

OFFSHORE SITE INVESTIGATIONS

Site investigations are necessary to assess ground conditions for services routing, renewable energy investigations, resource mapping, infrastructure installations, navigation route planning, dredging and constructions.

Providing Engineering Services for Taiwan Offshore Wind Farm

Metricon together with its partners undertake offshore hydrography and investigation for energy resources exploitation and blue economy infrastructure projects that include.

GNSS positioning
Depth Sounding
Water Level Gauging
Wave and non-tidal sea surface variation surveys

Hydrographic information infrastructure

Offshore/Onshore Positioning , Dredging & offshore construction Surveys

Offshore dredging and construction works relies on accurate survey hydrographic services that ensure accurate spatial placement of offshore structures, bathymetric surveys, tidal and water level measurements, hydrographic survey and computations of dredged materials.

Hydrographic survey services support underwater construction works like the construction of breakwaters, watercourse maintenance, deepening, restoration of beaches, and other engineering structures in coastal waters and sea bays.

Areas of Application

Dredging planning and maintenance
Monitoring changes in water depth, shoreline erosion, and mapping of subsea infrastructure such as pipelines, internet cables and wellheads.
Measuring sediment thickness and composition for dredging works.
Planning ,design, and assessment of underwater infrastructure e.g. docking anchorage, bridges, tunnels, and cables.

Mapping and identifying habitats, biodiversity hotspots, and potential conservation areas

There are several hydrographic survey methods ranging from variety of survey techniques and equipments deployed to gather data. SOme these methods include.
