RVO soon to open geotechnical survey tender for Nederwiek II & III

The Netherlands Enterprise Agency (RVO) plans to publish a call for tenders for geotechnical investigations at the Nederwiek Wind Farm Zone sites II and III in March 2023.

The contract will be divided into two lots.

Lot 1 will comprise executing an offshore seabed campaign, including seabed cone penetration tests (CPTs) up to 60m below seafloor (bsf), and temperature cone penetration tests (TCPTs).

Lot 1 will also include executing offshore vibrocores up to 6m bsf with associated laboratory testing.

Lot 2 will cover executing the offshore borehole campaign including laboratory testing. The campaign will consist of boreholes with a target depth of 60-80 metres bsf that could include sampling with associate laboratory testing (static and cyclic), MIC testing, in-site PCPT, and SCPT or PS logging testing.

The campaigns are planned for 2024 and the intention is to allow for an optional start (for Lot 1) at the end of 2023, according to the notice.

The estimated publication date of the contract notice is 15 March 2023.

The Dutch Government designated three new offshore wind areas and confirmed two previously designated areas in the North Sea in March last year. The three new wind energy areas are Nederwiek, Lagelander, and Doordewind, and the two reconfirmed areas are the northern part of IJmuiden Ver and the southern part of Hollandse Kust West.

With a combined capacity of 10.7 GW, the new areas will double the country’s total planned capacity for offshore wind energy to around 21 GW by 2030.

In June 2022, the Government disclosed the tendering timelines and locations for nine offshore wind projects with a combined capacity of up to 13.4 GW, which includes a previously identified area, on top of the new ones.

The 2 GW Nederwiek Zuid I is scheduled to be auctioned off in the second quarter of 2025 and is expected to come online in 2030.

The 2 GW Nederwiek Noord II and III are to be auctioned off in 2026 and are scheduled for commissioning in 2030 and 2031, respectively.
