RWE to Carry Out Pre-Installation Survey at Vanguard West OWF Site

Why It Matters

The survey moves the Vanguard projects toward construction, confirming RWE’s timeline and investment, and supports the UK’s offshore wind expansion and climate goals.

Key Takeaways

• Survey vessel Breaker starts June 15, one‑month offshore wind survey.
• Vanguard West holds 1.4 GW capacity, commissioning targeted for 2029.
• RWE secured CfDs and partnered with KKR, FID expected summer 2026.
• Vestas 15 MW turbines ordered for both Norfolk projects.
• Lamprell begins manufacturing transition pieces for Vanguard farms.

Pulse Analysis

The pre‑installation survey at RWE’s Vanguard West marks the first on‑site activity for a project that will add 1.4 GW of clean power to the United Kingdom’s offshore wind portfolio. Mobilising the survey vessel Breaker from the Dutch port of Den Helder around June 15, RWE will spend roughly a month mapping the array area and verifying seabed conditions. The effort follows the award of contracts‑for‑difference (CfD) for both Vanguard West and its sister farm Vanguard East in the UK government’s seventh CfD round, a key regulatory step that locks in revenue streams and de‑riskes the development.

RWE’s procurement strategy underscores the scale of the venture. In early 2026 the company placed firm orders with Vestas for its V236‑15.0 MW turbines, the largest on‑shore‑class machines currently available, which will be installed across both Norfolk sites. Meanwhile, Norwegian contractor Lamprell has begun fabricating the massive transition pieces that connect turbines to the foundations, reflecting a maturing supply chain. The combined turbine capacity of 2 760 MW across Vanguard West and East is slated for commissioning in 2029 and 2030 respectively, aligning with the UK’s target of 50 GW offshore wind by 2030.

The survey’s progress signals that RWE is on track to issue a final investment decision this summer, a milestone that will likely unlock further equity from its partner KKR. By advancing one of the country’s biggest offshore projects, RWE not only expands its renewable footprint but also contributes to the UK’s decarbonisation agenda and creates a pipeline of jobs in engineering, construction, and operations. Investors are watching the timeline closely, as successful execution could set a benchmark for future large‑scale offshore wind developments in Europe.
