One of the core components of this initiative is the development of a pan-European hydrogen pipeline network in the North Sea, designed to connect major hydrogen producers with key consumers across the continent.?AquaDuctus is Part of this future pipeline network. AquaDuctus project consists of an offshore part (Exclusive Economic Zone (EEZ) and territorial waters of the German North Sea and a receiving terminal at the coastline of Lower Saxony) and an onshore part to make connection with the onshore grid. AquaDuctus is planned as a large diameter pipeline (48 inch) with a transport capacity of 20 GWH2 and a design pressure of 120 bara. The conceptual design of the pipeline enables the connection of neighbouring European hydrogen infrastructures and the planned production facilities in the German EEZ (SEN-1 Area). The procurement item consists of four lots. On the offshore part of the project (Lot 1 and Lot 2) the pipeline is expected to be mostly buried in the seabed and the crossing of the shore will be done via tunnelling. For the offshore part there are two sections to be considered. Section I extends from shore to the area of SEN-1. Section II extends from SEN-1 to the end of the German EEZ. Section II is an option in this procurement procedure and may only be awarded together with Section I. For the purposes of the offer evaluation, the contents of Section I and II will be considered. The evaluation of Sections I and II for the respective services (Scope of Work packages A and B) is based on an equal weighting of 50% each. Due to administrative requirements, separate approval is necessary for Section II, therefore it is designated as an optional position. Lot 3 covers the geophysical and geotechnical surveys needed for the project section in shallow waters. Lot 4 covers the geotechnical surveys needed for the tunnel section of AquaDuctus pipeline. Owner of the Project (Client) is the AquaDuctus Pipeline GmbH. GASCADE Gastransport GmbH is acting as General Service Provider for the AquaDuctus Pipeline GmbH and will be responsible for the surveys.
