Re-use of immersed tunnels: An innovative method for recovering, regenerating and reusing immersed tunnels by temporarily re-floating

Immersed tunnels, located in waterways, could be a limiting factor in the dredging in waterways. This dredging is required since cargo vessels draught increased the past decades. In this thesis a new method is defined for temporarily, effectively, re-floating immersed tunnels. With this method extra risks arise, for these risks’ measures are...

Optimal construction and transportation method for gravity based foundations for offshore wind farms on commercial scale: Application of a new developed design method

A new trend to found offshore wind turbines at larger depths or on harder soils is to apply gravity based foundations (GBFs). These foundations are caissons with a set of properties which are different with respect to other caisson types. The number of constructed caissons is large and the timeframe for construction and transportation from land...
