Survey

Nothing in this country is truly known until it is sounded. Barlovento Survey produces the measured truth of lagoon, reef and channel — bathymetry, tides, volumes and seabed condition — to a standard that lenders, insurers and tribunals accept without argument.

Services

02.1

Bathymetric & topographic survey

Seamless models of the land–sea interface where every Maldivian project lives. We run singlebeam and multibeam bathymetry across lagoons, channels and approaches, and RTK topographic survey over islands and reef flats — merged into one digital elevation model your designers can build on.

SCOPE — multibeam & singlebeam bathymetry (MBES/SBES) · RTK GNSS topographic survey · seamless land–sea DEMs · survey control establishment & datum documentation · nautical-chart-style plans and GIS/CAD deliverables

02.2

Tidal, current & metocean observation

Design inputs for structures that live in moving water. We deploy tide gauges to establish and transfer chart datum, profile currents through channels and passes, and run wave and metocean campaigns that turn design assumptions into observed values.

SCOPE — tide gauge deployment & chart datum establishment · ADCP current profiling · wave & metocean measurement campaigns · datum transfer between islands · data reduction & reporting for design use

02.3

Dredge & reclamation volumes

Where the money moves in cubic metres, the survey is the contract. We run pre-, interim- and post-dredge surveys with documented methodology and uncertainty, computing quantities to a standard built to withstand commercial dispute — for contractors and employers alike.

SCOPE — pre-dredge baseline surveys · progress & interim surveys · post-dredge & acceptance surveys · volume computation & independent verification · progress certification support

02.4

Geophysical & environmental survey support

What the echo sounder cannot see, the project still pays for. We image and classify the seabed — obstructions, debris, sediment character — and deliver the physical baseline data that environmental impact assessments and consenting processes depend on.

SCOPE — side-scan sonar imaging · seabed classification & obstruction surveys · sub-bottom investigation coordination · EIA physical baseline data · pipeline, cable & outfall route surveys

Typical deliverables

Survey reports with control & uncertainty documentation · bathymetric charts & plans (PDF/CAD/GIS) · XYZ & gridded datasets · volume computation reports · tidal & metocean data packages — aligned to IHO S-44
