Keller has the experience and expertise to construct long jetties into deep water to allow the berthing of large vessels without the need for any dredging.
Execution methods are adapted to the specific conditions of each project but would typically require the fabrication of a platform on which a crane would install at the same time :
- The piles of the next span through a cantilever guide
- The permanent structure of the jetty on the current span
- The slabs of the jetty on the former span
Allowing incremental construction from shore in this way makes this process fast and cost-effective, and provides a value-for-money solution.
If execution of piles in hard soil takes too long compared to the rest of the tasks, a temporary jetty can be erected alongside the permanent jetty to allow safe and permanent access to the works along the full length.
