Underwater Mapping / Dredging / Seabed mapping / Bottom relief / Seafloor mapping.

A bilateral agreement was signed to conduct bathymetric and topographic surveys on the “DALGA LITE, MARDAKAN” project (Caspian Sea). The companies have started the bathymetric survey in the project area for us, as per the contract they signed. The completion duration of the project has been 11 calendar days (ahead of the due time). The specialists compiled a 1:500 scale bathymetric map based on the results of bottom relief surveys. The team conducted bathymetric surveys using a single-beam echo sounder system. The team developed a bathymetric model to calculate volumes.

Results:

Researchers used various methodological approaches to conduct bathymetric and topographic surveys. The main objective was to study bottom relief. However, to study bottom relief and conduct topographic surveys in coastal areas, researchers need to map the seabed and create bathymetric models with high resolution. Initially, we carried out a risk assessment on the territory, prepared an HSE and an Emergency Action Plans, and reduced all risk probabilities to a minimum level.

Firstly, after visually inspecting the area, we first conducted a detailed analysis of the entire area. The team conducted a topographic survey on a scale of 1:500 in accordance with the technical assignment. Specialists used a hydrographic echo sounder for seabed mapping, conducted a topographic survey with GPS receivers, and performed depth surveys in the Baltic Height System. After that, we determined the depth points of the basin bottom relief and applied the results to cartographic products. As a result, maps and models (bathymetric model, seafloor mapping etc.) met the Customer’s requirements.

In conclusion, we have presented an 85-page report that clearly details the methodology, data about maps, and models used in our work.

Dalga Lite is a clean and fully equipped beach venue for those who seek a relaxing time on the Caspian seashore in comfort and serenity.
