Geotechnical Studies

The objective of this activity is to investigate the geological and hydrological aspects of a maritime-port project. The information is used in the selection of construction alternatives for the project, among other aspects

Hydrographic Services

Our Company Dragados y Puertos S. R. L. of C. V. is a pioneer in offering hydrographic services in the North Pacific area of ​​Mexico. We have extensive experience in high quality hydrography services oriented to Marine Construction and Research. We have worked providing hydrographic and topographic services to private companies, state and federal government.

In maritime ports and terminals, bathymetries are indispensable to achieve a certain elevation that allows security in the internal navigation and the operation of ships.

Hydrography

• Bathymetric Surveys with Multibeam Echosounder
• Side Scan Survey and magnetometer.
• Surveys with Sub-Fund Profiler (subottom profiler).
• Underwater inspections with HD video.
• Digital cartography services, Geographic information integration
• 3D representations

Bathymetries

Precision bathymetries for areas of studies and projects with the help of RTK GPS, which provides position correction and elevation in real time instead of tide correction.

Behavior and distribution of silts in navigation channels, docks of ciaboga, parament of springs.

Dragados y Puertos has the latest technology in terms of bathymetric surveys, incorporating a 512 Haces Odom MB1 multi-beam echo sounder into its hydrographic equipment.

• Control bathymetries for calculation of dredged volumes.
• Obtaining sections and profiles. Identification of objects on the seabed.
• Location of submerged structures such as pipes, ballasts for anchors, etc.

Lateral Sweep Surveys

Side Scan Sonar surveys are specially required to obtain large aerial images of the seabed. These can be used for different purposes such as:

• Identification of submerged structures.
• Search for objects.
• Classification of sea floor surface material such as sand, rock, mud, etc.

Surveys with Magnetometer

The magnetometer surveys are used to locate structures with submerged metal components such as:

• Steel pipes covered with sand or mud.
• Ships buried under the seabed.
• Structures covered by material in the background.

Surveys with Subfund Profile

Surveys with subfund profiler are used to identify the different strata of the marine subsoil, the main applications of this type of surveys are:

• Identification of layers of azolves.
• Studies to support piles.
• Projects of docks and ports.
• Geological mapping.
• Foundation of bridges.

Underwater Inspection

Dragados y Puertos offers comprehensive underwater inspection services where by means of diving and high definition cameras you can obtain images and videos of the areas of interest

• Identification of submerged objects.
• Pile Inspection.
• Inspection of Buoys.
• Identification of underwater fauna and flora.
• Inspection of ship hulls.

Planning, quantification and progress evaluation of Dragados

Evaluation of the accumulation of dredged material in Shooting Sites (dumping sites for dredged material).

Positioning

Positioning of platforms, barges, buoys and marine structures with the help of RTK GPS.

Digital Cartography

The objective of this activity is to investigate the geological and hydrological aspects of a maritime-port project. The information is used in the selection of construction alternatives for the project, among other aspects.

Core extraction and seabed sampling

We have the capacity to extract cores and samples from the seabed at depths greater than 300 feet using a hydraulic underwater drilling machine.
