Towing of tunnel element for Citybanan Stockholm via Södertälje lock September 2009 until June 2012. For more information see Youtube clip from the complete work: https://youtu.be/S6_e3YG156s
The steel shell, which was transported through the lock is 108 metres long, 20 metres width and 10 meters height. This should make the steel shell impossible to tow through the channel because it is 40 inches too wide. But a solution was founded.
- It was placed on a barge which was equipped with a 3.5 meter tall steel construction. The 1870 tonnes heavy shell resteds on the steel structure. In that way the stell shell will pass the quayside of the lock. The lock was only 18 metres width.
STS MARINE CONSULT acted as Tow Master and prepared towing manuals for Pihl / Zublin JV Söderströmstunneln HB until all elements were moored safely alongside in Stockholm.
