At the request of the Ustka Municipality, “Hydro-Naval” Adkonis, Michałek, Sobków Spółka Jawna built a turning footbridge in the Ustka harbour that connects the eastern and western part of the port.
The “Colosseum” Design Studio provided the architecture design, while the structure design had been prepared by the Polski Rejestr Statków S.A.

The entire load of the structure rests on the western bank of the harbour channel. The bridge rests on the turning bearing, on the same side as the 24m pylon which opens the bridge.

On the eastern side, the footbridge rests on hydraulic girders that lock the footbridge with the abutment. The platform of the footbridge is held and balanced with the guy bars attached to the pylon.
The footbridge is meant to provide an easy walk over the harbour channel. As it can be opened or closed, the port operation has not been affected.

The footbridge has steel structure. The length amounts to 57.78m while the width equals 4m. The whole structure weighs over 80 tons. It takes about 4 minutes to open. The footbridge can turn with the wind not exceeding 10 m/s (36 km/h) and the visibility of at least half nautical mile.

Overall, the footbridge definitely improved connection between the both sides of the sea resort, and may become a tourist attraction in Ustka.

Processes of welding of complex metal structures, such as those used by the offshore oil industry or the bridge structures, are crucial for the quality of the end product. These products require a great precision, and therefore appropriate supervision over the construction, starting from the design onwards, is very important. This follows from the very nature of welding, as the quality cannot be assessed without destruction of the product, and even the advanced non-destructive testing will not improve the quality of what had already been done. In 2013, we received the ISO 3834-2:2005 certificate that addresses the quality requirement regarding metals welding and covers manufacturing and sales of the on deck systems as well as manufacturing and sales of the oil industry production systems. Our welding QC system accreditations confirm that the steel structures delivered by the Hydro-Naval meet the requirements set forth in the standardisation documents, template specifications and the legislative rulings.
