Guiding Rampion 2 Offshore Wind Farm Through Complexity to Consent

APEM Group - Case Study

APEM Group, through its specialist consultancy GoBe Consultants, played a pivotal role in securing development consent for the Rampion 2 Offshore Wind Farm – an ambitious renewable energy project off the Sussex coast in the United Kingdom.

Project Overview

GoBe led the offshore Environmental Impact Assessment (EIA) for Rampion Extension Development Limited (RED), a joint venture led by RWE Renewables, in collaboration with project partner WSP, who acted as the overall lead consultant and onshore lead. The project also showcased strong cross-company collaboration within the APEM Group, with the APEM Ltd ornithology team leading the ornithology chapter, assessing baseline data collected by the Marine Wildlife Survey (MWS) team, and working closely alongside the GoBe technical teams. This multi-disciplinary effort highlights the strength of integrated teamwork across the Group’s companies and specialist teams. The project, which will feature up to 90 turbines, is expected to power over one million homes and reduce carbon emissions by approximately 1.8 million tonnes annually.

Project Context

Rampion 2 builds on the success of the original Rampion Wind Farm and represents a significant step forward in the UK’s transition to clean energy. Since GoBe’s inception in 2009, the team has supported RWE on numerous offshore developments. For Rampion 2, GoBe and APEM worked closely with RED over four years to navigate the complex regulatory landscape and deliver a robust EIA that met all legislative and policy requirements for nationally significant infrastructure projects.

Key Stats

  • Timeline:
    • Consent awarded: April 4 2025
    • Construction start: Planned for 2027
    • Operation: Expected by 2029/30
  • Key Disciplines Involved:
    • Benthic ecology, delivered by GoBe
    • Fish ecology, delivered by GoBe
    • Marine physical processes, delivered by ABPmer
    • Marine mammals, co-delivered by GoBe and SMRU Consulting
    • Ornithology, delivered by APEM Ltd

Project Challenges

Rampion 2’s location presented several environmental sensitivities, particularly regarding species vulnerable to underwater noise. The project required careful coordination with statutory nature conservation bodies (SNCBs) and the integration of multiple ecological disciplines. The challenge was to develop a project that balanced renewable energy goals with the protection of marine biodiversity.

Solution

GoBe led the offshore EIA process, coordinating all environmental surveys and assessments and delivering expert analysis across key ecological areas through its multidisciplinary teams. APEM supported this effort by conducting the baseline Digital Aerial Survey (DAS), which provided critical data on seabird and marine mammal populations to underpin the wider environmental assessment and ensure a robust evidence base for decision-making.

A major innovation was the development of a novel underwater noise (UWN) mitigation strategy, pioneered collaboratively by GoBe, Subacoustech Environmental, itap GmbH, and the RWE engineering team, following extensive consultation and engagement with statutory nature conservation bodies and the Marine Management Organisation (MMO).

In addition, GoBe played a key role in developing the Measures of Equivalent Environmental Benefit (MEEB) case for the Marine Conservation Zone (MCZ) assessment and undertook a detailed pre-application routeing study for the export cables, ensuring optimal alignment from the array area to the landfall.

This integrated approach ensured that the project met all regulatory requirements while minimising environmental impact.

Matt Burling, Offshore Project Manager – GoBe:

“Rampion 2 showcases what’s possible when innovation, collaboration, and environmental stewardship come together. We’re proud to have helped bring this transformative project to life.”
