MULTIBEAM BATHYMETRY

SINGLEBEAM BATHYMETRY

High resolution bathymetry with 100% coverage of the seafloor through

multibeam echo-soundings and course correction, pitch, roll, yaw, and

sound velocity.

Bathymetric studies with dual-frequency and single-frequency echo

sounders that allow greater precision in all types of aquatic floors.

PRODUCTS

MAGNETOMETRY

SIDE SCAN SONAR

It allows the detection of ferrous materials that are found on the seabed

either on the surface or buried in the area being studied. This is determined

by the anomalies detected at Nanotesla (nT) level.

Technology that allows the creation of acoustic images of the surface of

the seabed, as well as carrying out georeferencing and characterization

of decks, detection and search of objects, inspection of structures and

monitoring of marine works.

PRODUCTS

SUB-BOTTOM PROFILING

CURRENT METER

Methodology of geophysical exploration based on the principles of vertical reflection

physics, with this method low frequency acoustic records, reflected in the marine

subsoil that allow to discriminate the interfaces between different layers of materials

are obtained. We have high resolution “pinger” and “boomer” type profilers of greater

power.

We have this instrument to measure the speed of the current in the

sea, rivers and other bodies of water, we have equipment such as

the Acoustic Doppler Current Profiler (ADCP) and propeller-type

meters for different types of studies.

With ADCP technology we can also measure wave height after a

series analysis of the data.

PRODUCTS

MARINE ELECTRICAL TOMOGRAPHY

MARINE SAMPLING

It is a multi-electrode resistivity method, based on 2D terrain modeling using

numerical techniques. This allows identifying lithologies and morphologies of

the subsoil, as well as locating objects.

We have Vibro Corer, Gravity Corer, Grab Corer and other equipment

to help classify and describe samples taken from the seabed.

PRODUCTS

CTD´s, MULTIPARAMETER PROBES AND TIDE GAUGES

GPS’s

They allow measuring different variables and parameters, such as:

oceanographic conductivity, temperature, depth, salinity, density,

and dissolved oxygen, etc.

We have different high-precision positioning technologies with

Omnistar XP or ground-based (RTK) satellite corrections for

maximum reliability in achieving data accuracy.

PRODUCTS

MARINE EQUIPMENT

SOFTWARE

Geomares has different equipment for the development of marine works

such as: winches, cranes, compressors, generators, dredging and suction

pumps, four-point anchoring systems, cable motors, and burial equipment

for submarine cable.

We have specialized software for different types of hydrography as well

as marine geophysical equipment, which allow us to make the best use

of the data obtained in order to develop final products adjusted for

different segments such as Oil & Gas, Telecommunications, and Engineering

amongst others.

PORT STUDIESOur services range from the characterization of the sea bed and

sea bottom areas as well as the coastal area for the construction

of new ports to studies for maintenance and verification of port

structures. Port geophysical studies are vital for piling planning

and cost reduction in the port construction phase.

.

Through the combination of technologies including multibeam bathymetry,

side scan sonar, sub-bottom profiler and magnetometry we determine

the existence of shipwrecks and other archaeological findings which is

indispensable for obtaining the permits from ICANH and other entities for

port, submarine cable and pipeline projects, Oil & Gas, and general dredging

in marine environments, they also help in the determination of the state and

hthe necessary tools for the rescue of wrecks and other marine artifacts.

SOLUTIONS

We perform pre-dredge and post-dredge marine geomorphological

characterization which allows us to calculate dredging volumes with

high accuracy, and taking into account the characterization of materials

performed with t he sub-bottom profiler and bottom samples such as

vibrocorer and others; it is possible to determine the optimal type of

dredging needed for each area, performing the environmental study of

the type of material and its components for the dump area thus

permitting planning and cost reduction.

DREDGING: PLANNING ANDCONTROL

COASTAL ENGINEERINGWe conduct studies of marine dynamics that allow us to

make models designed for different types of coastal

projects. These studies help to prevent the impacts of

coastal erosion, and develop the realization of artificial

beach projects, piers, and other coastal protection works.

SOLUTIONS

POSITIONING OFPLATFORMS AND OIL STRUCTURES

CURRENT AND SEDIMENTTRANSPORT STUDIES

It is vital for the determination of different projects in rivers, reservoirs

and coastal zones. Through the use of technologies such as current

meters, liquid and solid amphorae and hydrodynamic models we

can determine factors such as the useful life of reservoirs, coastal

erosion and littoral sedimentation phases, in addition to sediment

calculations in navigation channels in rivers and ports.

SOLUTIONS

Throught precision centimetric GPS and specialized navigation

software, Geomares provides positioning services for barges

and oil structures with the safety required by the OIL & GAS

and others from the engineering sector.

CALCULATION OF AREA AND VOLUME FOR RESERVOIRS

NAVIGABILITY STUDIESThe bathymetry and sedimentology in rivers and navigation

channels allows us to carry out nautical cartography besides

performing the analysis of navigability of the bodies of water.

SOLUTIONS

With the use of single beam, and multibeam bathymetry and LiDAR

topography, we perform the precise calculation of volumes and

characteristic levels required in hydroelectric projects, lakes, and

dams in order to comply with CNO requirements and to foresee the

useful life of the reservoirs.

SOLUTIONSSUBMARINE CABLES

Submarine cables

ROUTE STUDY FOR SUBMARINE CABLES AND PIPELINES

SOLUTIONS

With the combination of multibeam bathymetry, sub-bottom

profiling, side scan sonar, magnetometry and sea bed

sampling, we have studied ideal routes for laying cables and

underwater pipelines, as well as the profile and tools

needed for its burial.

Geomares manages international standards in terms of

data acquisition and quality and presentation in GIS, CAD

and other formats required by the industry’s clients.

Our specialized equipment can detect submarine cables,

cperform geo-location, and find intersections on new routes.

SHORE END LANDING, INSTALLATION AND MAINTENANCE OF SUBMARINE CABLES

SOLUTIONS

Geomares has the capacity, experience and the necessary equipment for the

the landing, installation and burial of submarine cables. We have experience

in burial under difficult conditions and shallow water including burial in

different seabed materials such as sand, rock, clay and silt.

Due to our strategic location and operation capacity, we are an efficient

solution for the maintenance of submarine cables in case of damages caused

by incidents with anchors, and climatic or technical factors. We handle

turnkey solutions that adjust to the times needed for a rapid deployment

allowing repairs to be made in the shortest possible time avoiding greater

losses for the cable operator.

We have an operating license in Colombia that streamlines procedures and

times for installation and maintenance of submarine cable, making

pre-operational times and costs efficient when compared to foreign

competitors.
