Building a better future together

Petrofac is a leading international service provider to the energy industry, with a diverse client portfolio including many of the world’s leading energy companies. We design, build, manage, and maintain energy-producing infrastructure and our purpose is to enable our clients to meet the world’s evolving energy needs.

We have been deploying our capabilities to support the offshore wind sector for over a decade. In that time, we delivered close to 4GW of offshore and onshore transmission assets - HVAC and HVDC - for clients across the UK and Europe.

Today, we continue to grow our portfolio of projects, forge new partnerships and adopt new ways of working to accelerate the delivery of wind projects globally.

Recent projects

In 2023, we signed an offshore wind framework agreement, along with our partner Hitachi Energy, for TenneT’s ground-breaking 2GW offshore wind programme. The framework covers six renewable integration systems, five that will connect offshore wind farms to the Dutch grid and the sixth to the German grid. Each connection system has a capacity of 2GW and a voltage level of 525 kilovolts, a world-first for offshore wind. We will deliver the engineering, procurement, construction and installation of the offshore platforms and elements of the onshore converter stations. The first project will be the Ijmuiden Ver Alpha project.

In 2020, Seagreen Wind Energy, a joint venture between SSE Renewables and TotalEnergies, awarded us the engineering, procurement, fabrication, transportation, offshore installation and commissioning of the onshore and offshore HVAC substations. This is currently the world’s deepest fixed-bottom wind farm, and we engineered and built the six-legged jacket to withstand the harsh North Sea environment. At 83m it was transported horizontally from the UAE to its location 27 kilometres off the coast of Angus. The jacket was safely installed between 2022’s Storm Arwen and Barra, and the topside followed shortly after.

We completed the engineering, procurement, construction, and offshore installation of the Hollandse Kust (zuid) (HKZ) High Voltage Alternating Current (HVAC) transformer stations, Alpha and Beta – for TenneT’s offshore grid connection project in 2022. Both transformer stations were designed and built in the UAE. HKZ is the first subsidy-free wind farm area in the world. When operational later this year, it will generate enough renewable power for more than two million Dutch homes.

In 2019, in consortium with Siemens, we completed the BorWin3 offshore wind grid connection project for TenneT. We were responsible for the engineering, procurement, construction, and offshore installation (EPCI) of the BorWin gamma platform, housing Siemens’ HVDC station. In one of our most challenging projects, we deployed an innovative float-over technique – a first for the region – to install the 18,500-tonne topside, using dynamic positioning technology and a semi-submersible vessel.

Running assets better for longer

Our services extend across the lifecycle of transmission assets, into maintenance too.

In fact, our offshore wind story began back in 2009 when we provided people, maintenance, and support services to the world's first-ever HVDC converter station, TenneT’s BorWin Alpha.

Today, we offer maintenance solutions, from the tip of the blade to the seabed and onwards to balance-of-plant onshore.

We deploy multi-disciplinary teams, supported by our in-house engineering and technical teams and use connected technology and predictive maintenance tools to ensure wind assets run better for longer.

Multi-disciplinary teams

Our GWO-trained technicians and tradespeople include electrical, mechanical, instrumentation, inspection, rigging and lifting.

Technical and engineering support

Our integrated approach combines the hands-on skills of our local offshore technicians with the expert knowledge of our engineers and specialist subject matter experts. This access to our engineering specialists is what sets us apart in support of live operations is what sets us apart.

AI-enabled insights

Using digital tools we’ll transform asset and project data into actionable insights. This supports effective planning, and the rationalisation of maintenance programmes as well as reducing unplanned downtime and the number of trips offshore. This technology is proven through work supporting offshore oil and gas assets, where it is an established part of our working practices.

Connected workers

By digitalising the planning, execution and reporting of maintenance activities, we maximise on-site productivity and minimise operational costs. Connecting our on-site technicians directly to engineers and specialists means they can receive advice and guidance in real time, further reducing delays and unplanned downtime

Global experience, local capability

We are committed to investing in the supply chains wherever we work.

In 2022, OEUK awarded us ‘Supply Chain Company of the Year (Large Enterprise)’ in recognition of our commitment to developing and strengthening business relationships with suppliers.

We focus on partnering and working together to align the commitment of executive leadership teams, supply chain drivers and objectives in a way that benefits everyone. This means developing long-term relationships, strategic partnerships and reducing waste and cost for the supply chain through optimised sourcing strategies.
