Innovative solutions building a new container berth

In order to increase the capacity of a container terminal it became necessary to build a berth for the biggest container-vessels. Building a new berth demands high standards as regards construction and building technology so that an optimum solution in terms of both technology and economic viability can be found. In a Europe-wide compeeition efficient companies and/or groups of tenderers were looked for. Among these applicants was then held a „contest of ideas” which aimed at finding innovations, developing compaany-peecfic ideas and at concentrating offers of ideas and prices in one procedure. The following constructive options were presented: steel sheet-piling with various installation techniques, diphragm walls (slurry-wall-technologies) and caissons. Pour l’extension des capacites d’un terminal, il a ete necessaire de construire un nouveau mouillage pour les plus grands navires porte-conteneurs. La construction de celuici a constitue un veritable defi quant a la conception et a technique de construction, des lors quil s’agissait de trouver une solution optimale, tant du point de vue technique qu1economique. Un concours organise europeen a permis de decouvrir des entrepreises ou groupements de soumissionnaires performants; les concurrents ainsi choisis se sont alors affrontes dans le cadre d’un concours de conception, ayant piur objet la decouverte d’innovations, le developpement d’idees specifiques yus entreprises, ainsi que la concentration des aspects idees et prix dans le cadre d”une seule procedure. Voici les suggestions qui en sont ressorties: Rideaux de palplanches metalliques, Construction de rideaux souterrains et Construction a base de caissons fonces. Les divers modes de construction seront expliques et evalues des points de vue technique et prix.
