The underwater positioning service aims to determine with high precision the geographic coordinates and depth of points or objects on the seabed. Through sonars, GPS/GNSS, and advanced navigation systems, Mitang maps underwater locations in detail. This process is essential for:

• Planning underwater projects (installation of platforms, fixed or semi-submersible structures).

• Reducing risks and preventing unforeseen events during construction and installation phases.

• Ensuring compliance with environmental regulations and licenses, guaranteeing technical conformity.

Our installation support includes comprehensive underwater surveys to assess site conditions for deploying various submerged infrastructures or equipment. This stage involves:

• Preliminary seabed analysis, identifying depths, potential obstacles, and geological conditions.

• Evaluation of stability and safety to support structures such as platforms, heavy machinery, and pipelines.

• Identification of potential risks that could compromise the installation or long-term integrity of the infrastructure.

With reliable technical data, Mitang ensures the selected site meets safety and feasibility requirements, avoiding rework and reducing operational costs.

In cable and pipeline installation support, we conduct thorough underwater surveys to assess the condition and stability of the seabed where cables, pipelines, or underwater routes will be installed. The objectives are to:

• Map optimal routes, ensuring a safe layout for the lines and minimizing interference.

• Detect areas prone to erosion, presence of rocks, debris, or steep terrain that could compromise the installation.

• Provide technical input for selecting installation, protection, and post-installation monitoring methods.

This way, we optimize the installation process and reduce the risk of failures or interruptions during critical project phases.

Underwater metrology involves measuring and monitoring the position, orientation, and other parameters of structures or equipment in the marine environment. We use advanced techniques such as:

• 3D scanning, USBL/LBL systems, and other referencing tools.

• Alignment and integrity verification of structures like oil platforms, pipelines, and subsea cables.

• Dimensional control to ensure every submerged element is within specified tolerances.

With precise data, it is possible to detect misalignments or premature wear, maximizing equipment lifespan and preventing unplanned downtime.

After field data acquisition, our team of geophysics and data processing specialists applies QA/QC techniques to ensure data quality. We then prepare technical reports that include:

• Detailed maps of the construction or installation area.

• Interpretation and analysis of relevant underwater parameters (depth, substrate, interferences).

• Clear technical recommendations to support engineering decisions and ensure compliance with safety standards and regulations.

These reports serve as documentation for all parties involved in the project, facilitating coordination and transparency of operations.
