Following a decision in the Danish Parliament June 2020 Denmark is on the path to establish offshore energy infrastructure in the Danish North Sea and in the Danish Baltic Sea to connect offshore wind energy to the Danish mainland and to neighboring countries via offshore energy hubs, called Energy islands.
The current tender concern a concept study regarding initial engineering assessment and concept design of selected HVDC/HVAC substation concepts for the Danish Energy Island project in the North Sea.
The concepts shall assess feasibility and areas of optimization considering design, construction, fabrication, transport, installation, operation and maintenance and related risks, costs, and time schedules.
As minimum three specific concepts for 2GW transmission shall be assessed:
• HVDC/HVAC concept installed on an artificial island
• HVAC module(s) installed on an artificial island, and HVDC module(s) on a foundation (Steel-Jacket or GBS)
• HVDC/HVAC module/topside structure installed on a foundation (Steel-Jacket or GBS)
Other concepts, or combination of the above mentioned, may be proposed by the Consultant, and agreed with Client before initiation of the study.
The services shall be performed in close collaboration with Energinet to ensure relevance for the project and to handle interfaces to previous and on-going works.
The deliverables include the following documentation:
• Concept Study Report – HVDC/HVAC Concept
• Presentations of results – visual presentation of the results of the work and present it to Energinet in connection with delivery of the draft and final Report, respectively
• Technical presentations, where found relevant
Additional presentations, report of technical memos might be required on an ad-hoc basis.
The study is expected to be performed during Q2-Q3 2022.
The full suite of tender documents, including tender conditions, scope of services and contract draft will be issued to the prequalified applicants upon prequalification.
