Gepatsch Speicher Dam

The project started with dredging sediment using an airlift system to enable safe execution of saturation diving works. Dredging progress was closely monitored with survey equipment.

Following this, saturation diving operations were performed using the SAT 03 system. The main scope focused on the rehabilitation of the intake trash racks, including removal and installation of guide frames, gates, trash rack structures and associated components.

A key element of the project was large-scale underwater concreting at depths of 100+ meters, with a total of 950 m³ poured, including installation of an injection system and rebar net.

The project was completed with final cleaning and full demobilization, demonstrating DCN Diving’s expertise in deep-water saturation diving and subsea construction.
