90% of the rough construction of the project has been completed. The tubes have been sunken and the two continents have been linked 60 meters below the sea. The attention was on two things during the immersion of the tubes: fish migration and current above 3 knots. The work halted due to the current above 3 knots.
The work safety is at top level in the Marmaray project. 1.700 workers a month work for the project. No accident involving death has occurred during the project so far and 1.700 workers struggle for it not to happen. Each employee monitors the safety of the other.
According to the statement of the occupational safety specialist Gökhan Göker, Marmaray tunnel has been constructed to resist an earthquake with a much higher magnitude than that of the earthquake of 19 August. Marmaray, built to resist 7.5 moment magnitude earthquake, will shut down Marmaray 6 seconds prior to a possible earthquake thanks to an early warning system to be set up. The Marmaray tunnels have also been constructed to be resistant to any ship wreck or an attack during a war.
