The Hornsea 3 Podcast

In the sixth and final episode of the CDM podcast series, we take a slightly more potted look at the roles of Contractor and Worker. The series culminates with an explanation of how and why the CDM Regulations should be considered a useful (critical!) tool when it comes to managing a mega-project like Hornsea 3, and how people can get more help and advice if they need it.Host and speakersHost: Matthew Rumbelow, Head of Internal Communications, Hornsea 3.Internal Speaker: Graeme Lewis, UK Lead Design & HSE Specialist.Duration: 20 minutes.*Recorded in October 2025

In the fifth episode of the CDM podcast series with Graeme Lewis, we discuss the role of the Designer, and how practically any decision that affects the construction, installation or operation of our assets automatically assigns the role of 'Designer' to that person without the need for a specific appointment.  Host and speakersHost: Matthew Rumbelow, Head of Internal Communications, Hornsea 3.Internal Speaker: Graeme Lewis, UK Lead Design & HSE Specialist.Duration: 20 minutes.*Recorded in October 2025

This is the fourth episode of the CDM podcast series with Graeme Lewis, our resident CDM specialist. In episode four, Graeme takes a closer look at the role of Principal Contractor and some of the obligations and interactions associated with that role. Host and speakersHost: Matthew Rumbelow, Head of Internal Communications, Hornsea 3.Internal Speaker: Graeme Lewis, UK Lead Design & HSE Specialist.Duration: 40 minutes.*Recorded in October 2025

Graeme Lewis continues the CDM series with a look at the Principal Designer role, and why communication, coordination and alignment between interfaces is so critical for a project like Hornsea 3. As well as an exploration of some live aspects of the project where the PD role has come to the fore, we also discuss some of the essential deliverables in terms of the HSE file and why document control, tagging and handover is of fundamental importance for the long-term operation of the asset. Host and speakersHost: Matthew Rumbelow, Head of Internal Communications, Hornsea 3.Internal Speaker: Graeme Lewis, UK Lead Design & HSE Specialist.  Duration: 47 minutes. *Recorded in October 2025

In this episode, we continue the CDM series with a look at what it means to be 'the Client' under the Construction & Design Management Regulations. Graeme Lewis explains what the Client can and can't do, how the interface with the Principal Contractor and Contractors should work both in the pre-construction and construction phase of a project, and what some of the pitfalls can be when things go wrong. Host and speakersHost: Matthew Rumbelow, Head of Internal Communications, Hornsea 3.Internal Speaker: Graeme Lewis, UK Lead Design & HSE Specialist.  Duration: 33 minutes.

This is the first in a six part series featuring Graeme Lewis, our Lead Design & HSE specialist, looking at the different roles within the UK CDM Construction and Design Management Regulations. In this general introduction to the Regulations, we explore the background, context and purpose behind them, what the key roles and definitions are, and what role the Regulations plays on a multi-site, multi-party mega project like Hornsea 3. Host and speakersHost: Matthew Rumbelow, Head of Internal Communications, Hornsea 3.Internal Speaker: Graeme Lewis, UK Lead Design & HSE Specialist.  Duration: 13 minutes.

In this episode*, Bridgit is joined by Beatrice d'Eufemia, package manager for the Battery Energy Storage System adjacent to our OnCS.  In the final episode of the Boudicca series, we focus in on the first BESS in Ørsted's history to share a grid connection with an existing generator (Hornsea 3), and the complexities involved from a regulatory, commercial and legal perspective in making that happen. We look at the technology involved, the state of the battery market to date, and why the future may be looking towards longer-term energy storage solutions. Note: this episode was recorded prior to the mothballing of Hornsea 4.   Host and speakersHost: Matthew Rumbelow, Head of Internal Communications, Hornsea 3.Internal Speakers: Bridgit Hartland-Johnson, Chief Specialist PD Systems Integration, Beatrice d'Eufemia, PM for BESS.   Duration: 43 minutes.*Recorded in March 2025

In this episode, we're again joined by energy systems expert Bridgit Hartland-Johnson to discuss the merits of battery energy storage within the UK's energy network infrastructure. We start by turning the clock back to explore how and why Orsted's Battery Energy Storage System was conceived and the implications for Hornsea 3 and its pre-FID business case. Looking more widely, we consider why battery storage is important for the UK, what it can deliver for Orsted, and what the future looks like in terms of the country's overall generation mix.Host and speakersHost: Matthew Rumbelow, Head of Internal Communications, Hornsea 3.Internal Speaker: Bridgit Hartland-Johnson, Chief Specialist PD Systems Integration.  Duration: 1hr.

Episode 3 begins a three-part mini-series looking at the UK energy network and its evolution. In the first episode of the Boudicca series, our resident Systems Integration expert Bridgit Hartland-Johnson explains how the National Grid and UK infrastructure is having to adapt to changing government policy and the ongoing decarbonisation of the UK's energy mix. We go on to discuss how the energy market operates and why change is needed, before looking at some of the challenges involved in accommodating the ever-increasing supply from renewable energy sources like offshore wind.  The final two parts in the series will focus more on Ørsted and how projects like Hornsea 3 are navigating rapidly changing market forces and grid requirements, with a final in-depth look at Hornsea 3's co-located Battery Energy Storage System with our very own Iceni Package Manager, Beatrice d'Eufemia. Host and speakersHost: Matthew Rumbelow, Head of Internal Communications, Hornsea 3.Internal Speaker: Bridgit Hartland-Johnson, Chief Specialist PD Systems Integration.  Duration: 1hr 23 minutes (break at approximately 45 minutes).

In Episode 2, we join Hornsea 3's stakeholder relations team to look at how Hornsea 3 engages with local communities. Building the world's largest single offshore wind farm is one of the UK's most significant National Infrastructure Projects. With 52km of onshore export cables buried beneath the Norfolk countryside and an enormous onshore converter station site just south of Norwich, major civil construction work can be hard to manage in a very rural community.  In this episode, Imran Nawaz, Lauren Little and Lily Dowe join podcast host Mat Rumbelow to discuss strategies that have helped to offset the impact of construction through carefully organised local consultation and engagement activities. In addition to mitigating the negative impacts of a project of this scale, we also look at the positive impact Hornsea 3 is having through its £7million Community Benefit Fund, schools and colleges outreach programmes and community events.  

In the first episode of Hornsea 3's podcast series, we're focussing on mental health and wellbeing, looking at the impact mental health issues can have on individuals, organisations and families connected with the construction sector.  In this episode, Luke Bridgman and Phae Pritchard are joined by Sam Downie, Managing Director of 'Mates in Mind', one of the UK's leading mental health charities. With extensive experience in the sector and a background in psychology, Sam outlines some of the statistics around mental health in construction and explains how organisations can support their employees and contract partners through a structured programme of research, training, and the establishment of strong internal networks to create a culture where mental health can be discussed openly and honestly without fear or stigma. In a wide-ranging discussion, we begin by looking at some of the statistics around mental health, going on to explore how mental health and wellbeing can suffer as a result of post-pandemic work demands and increasing domestic and social pressures, We discuss ways people can develop resilience strategies to help them cope, and the importance of encouraging both self-awareness and a culture where managers and colleagues are helped to spot the early warning signs of colleagues who may be struggling.
