ECHOGRAM summary of the first half of 2026

The past few months have been exceptionally busy for Echogram. Over the recent months, our team has carried out a wide range of hydrographic surveys supporting some of the most significant marine infrastructure projects currently underway in Poland.

Echogram Team work has contributed to the successful execution of:

🌊 Bałtyk 2 Offshore Wind Farm
🌊 Baltica 2 Offshore Wind Farm
🌊 Baltic Power Offshore Wind Farm
⚓ Maintenance dredging works in the Port of Gdynia
🛟 Construction of the Outer Breakwaters in the Port of Gdynia
🚢 Operational maintenance of the Baltic HUB container terminals

Each project required precise hydrographic measurements, detailed seabed mapping, and reliable data to support safe engineering, construction, and operational decisions.

We would like to thank our Clients for their trust and our entire Team for their dedication, professionalism, and commitment. It is thanks to their expertise that we continue to deliver high-quality hydrographic data for complex maritime projects.

We are proud to support the development of offshore energy and modern port infrastructure in the Baltic Sea.

Echogram – Precision. Technology. Experience.

As part of the project entitled: “Execution of construction works under the project ‘Reconstruction of the Tczew Bridge – Stage II’,” the company Echogram carried out geophysical surveys on a section of the Vistula River in the immediate vicinity of the water-based construction site and the river fairway.
The outcome of the work is a developed bathymetric map together with a sonar mosaic.
Additionally, based on the survey results, a shipping and navigation analysis was prepared along with a proposed navigation aids and marking system for the investment project.
During the implementation of the project, the works will involve the dismantling and relocation of the ESTB bridge span structure, as well as the construction and foundation of a new main-river support pier. The transport of materials and the execution of most of the works will be carried out using floating equipment.

ECHOGRAM Team are proud to announce that Echogram has commenced geophysical surveys as part of the strategic investment project:
“Construction of breakwaters constituting the water access infrastructure to the Outer Port in the Port of Gdynia under the design and build formula.” The project is being carried out by the consortium: BUDIMEX S.A., ROVERPOL Sp. z o.o., and ROVER MARITIME S.L. Spółka Cywilna.
As part of the project, Echogram will provide bathymetric support services throughout the investment process. In the initial phase of the project, pre-construction surveys have already been completed.
This investment marks an important step towards the future expansion and development of the Port of Gdynia.
For many years, Echogram has had the privilege of providing services for the Port of Gdynia, and we are honored to contribute once again to the development of one of the key maritime hubs in the Baltic region.
