Published: 2022-06-13
Buyer: TenneT TSO B.V.
Country: NL
Contract type: Services
CPV classification: 76520000

Technical requirements: Consultancy services for UXO investigations offshore, tidal and beach areas. Services are performed in function of the development of offshore wind farms and directly related to the installation of platforms and export cables.
The law "Wind energy at Sea" of July 1, 2015, intends to scale up wind energy in the Dutch sector of the North Sea. In this law TenneT TSO B.V. (hereafter Client) is the offshore grid operator. In this role the Client is responsible for engineering, procurement, installation, construction and operation of the connections between the offshore wind farms (through a converter platform) to the onshore network. The Dutch Ministry of Economic Affairs and Climate Policy designates the following areas for wind energy in the Dutch North Sea:
For these projects UXO consultancy services are required. This publication relates to the IJV Gamma project.

In this role the Client is responsible for engineering, procurement, installation, construction and operation of the connections between the offshore wind farms (through a converter platform) to the onshore network. The original UXO consultancy contract included the following projects:
This publication relates to removing the TNW project from the scope of services and adding the IJV Gamma project to the scope of services.
Cause and size of the change( this includes any former changes concerning this contract) the remaining works for Ten Noorden van de Wadden shall be removed from the current contract as a consequence of objections to the chosen route, the Ministry of Economic Affairs informed the Dutch parliament on the 2nd of December 2021 of the decision that the current project TNW will be revised and integrated in a broader program (3 projects with a total capacity of 4,7 GW). Part of this program is a reinvestigation of all route options (Waddenzee, Eemshaven West, Oost etc.) regarding several projects.
Consequence of this decision is that the TNW project will be integrated in a new program which is foreseen in the period after 2025 which is outside of the original time period of the Contract. This contract is being extended to cover the execution of UXO consultancy works for the Net op Zee IJmuiden Ver Gamma. This Net op Zee runs from the already allocated wind energy area IJmuiden Ver to the Maasvlakte. This IJver Gamma route will run mostly parallel with IJver Beta. The project Gamma and Beta ( and partly Alpha) are located in the same area and have overlapping route corridors. For the Net op Zee IJmuiden Ver Alpha and Beta, RPS Energy Limited has already been awarded the execution of the UXO Consultancy works. The project scope of work for IJver Gamma will remain the same as that of IJver Alpha and Beta.
Additional services are required and will be delivered by the original supplier because of technical and economic reasons. The present contract comprises the same activities as the additional services. The Gamma route largely runs parallel to the Beta route therefore most of the knowledge of this route and information on environmental effects can be re-used. A change would lead to significant inconvenience and cost increases for TenneT because knowledge of this route and information on environmental effects would be gained again by a new contractor, while the knowledge and environmental effects can easily be re-used for the Gamma route. Besides that a large part of the consultancy works consist of offshore representation of TenneT on board the research and clearance vessels. These vessels will be flexibly employed on the different routes without intermediate port calls. TenneT therefore avoids doubles costs when the representation on the various projects is done by the same consultant.
