Innovative Foundations
The contract(s) to be awarded concerns the design, fabrication, supply and installation of up to ten foundations and substructures for the support of 6MW-class wind turbine generators (WTGs). These WTGs will be provided by the contracting entity and the contractor(s) is obliged to co-operate with the WTG supplier in the execution of this contract. The transition pieces to establish connection between foundation and substructure with the steel tower supporting this turbine shall be provided by the contractor(s).
A maximum of three separate EPCI contracts could be awarded to supply these ten foundations & substructures. ‘Floating foundation’ and substructure concepts are prohibited. In this context, ‘Floating foundations’ are foundation and substructure concepts where buoyancy is a main component required for structural stability after installation. In contrast, floating transport is allowed.
The contract(s) will be only awarded to innovative foundation substructure concepts. These concepts must fit into one of the following design scopes:
a) Provision of a four pile steel foundation(s) and steel jacket substructure based on the steel jacket basic design developed for the standard Innogy Nordsee 1 substructure foundation and provided by the contracting entity during the negotiated procedure. There must be innovative modifications or additions to the design (e.g. modifications to joints, pile connection points, transition piece, the addition of damping etc).
b) Provision of a steel substructure, based on the aforementioned jacket design with the use of suction buckets as foundations.
c) Provision of an innovative substructure (and foundation) concept. This includes but is not limited to: non-conventional quad piled substructures, tripiled substructures, gravity based foundations, non-conventional monopile substructures, the use of suction bucket foundations.
A maximum of three separate EPCI contracts could be awarded to supply these ten foundations & substructures.
