D-Hamburg: foundation-design services

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.
