During the last ten years, the presentation of the COSUF Award Winner has been one of the highlights of the ITA COSUF meetings. The prestigious award is granted to a student, young professional or researcher in the field of operational safety or security of underground facilities. “Many of the previous winners have taken job positions in organisations that are working on operational safety of underground facilities. This is a good stimulation to continue to launch the award,” said Ben van den Horn, ITA COSUF General Secretary, commenting the steering board decision to award the 2019 COSUF prize.
Tough working conditions prevail in tunnelling. The demands posed on technical equipment are correspondingly high, as e.g. gears, which must reliably cater for movement in various machines. In tunnel boring machines (TBMs) planetary gears must withstand strong vibrations, impacts, high temperatures and pronounced external pressure. These powerful gears are also applied in building cranes, drilling rigs, cutters, excavators, pumps or tracked vehicles.

The fourth tunnel drive of the tunnel boring machine (TBM) „SUSE“ started in November 2018. Before that, the 120 m long machine had to be dismantled into seven pieces, which then were turned one by one underground. This article contains a short video clip of the unusual turning manoeuvre, made by the DB Projekt Stuttgart–Ulm GmbH.

The Porr bidding consortium won the tender for the construction project “A44, VKE 12, Tunnel Hirschhagen, Technische Ausstattung” at the turn of the year 2018/19. Porr Infra GmbH will be responsible...
The 2.2 km long Kaisermühlen Tunnel on the A22 Donauufer motorway is the longest motorway tunnel in Vienna. With a daily traffic volume of about 120 000 vehicles (of which 11 % are heavy goods vehicles), it is the most heavily used road tunnel in Austria. After a construction phase of about two years opperator Asfinag has now nearly completed the general refurbishment of all safety equipment (lighting, ventilation and fire protection) of the tunnel.
