When three of the North‑east's most established energy businesses. Port of Nigg, Global Energy (Group), and Global Energy Services came together under a single new brand, Maraen, it marked far more than a corporate re‑badge. It signalled a structural shift in how Scotland intends to compete in the global energy economy. And with more than £30 million of new investment now approved for the Port of Nigg, the implications for business growth, supply‑chain activity, and long‑term employment are profound.
The rebrand follows the 2025 acquisition of the businesses by Mitsui & Co. Europe and Mitsui O.S.K. Lines, bringing heavyweight international backing and a clear commitment to long‑term expansion. Maraen’s name combining Mara, Gaelic for "of the sea," and En for energy reflects both heritage and ambition. But the real story lies in what this integrated organisation can now deliver at scale.
A Port Being Rebuilt for the Future
The centrepiece of the investment is a new heavy‑duty quay and roll‑on/roll‑off (Ro‑Ro) capability, a development that will expand the port’s operational footprint by around 16,000 square metres. This is not a cosmetic upgrade. It is a strategic expansion designed to handle the next generation of energy infrastructure — from offshore wind components to high‑voltage subsea cables.
With planning consent and a marine licence already secured, construction is set to begin soon. A £10 million grant from Highlands and Islands Enterprise forms part of the Scottish Government’s wider £500 million commitment to strengthening the offshore wind supply chain.
For businesses, this means faster turnaround times, greater capacity for simultaneous operations, and a port capable of supporting the largest and most complex energy projects in Europe.
A New Industrial Ecosystem for Offshore Wind
The Port of Nigg is already recognised as a strategic hub for offshore wind, having supported the deployment of more than 4GW of capacity. The new quay will deepen this role by providing a dedicated load‑out and export facility for high‑voltage cables manufactured at the adjacent Sumitomo Electric HVDC plant.
This creates a tightly integrated industrial ecosystem: cables manufactured on site, loaded directly onto vessels, and shipped to offshore wind farms across the UK and beyond. It is the kind of vertical integration that attracts global developers — and the kind that anchors long‑term jobs in the region.
What It Means for Employment
The investment is expected to stimulate job creation across the supply chain, not only within Maraen itself but across dozens of supporting industries:
fabrication and engineering
logistics and haulage
marine services
specialist offshore contractors
accommodation, hospitality, and local services
While exact job numbers have not been published, the pattern is clear. Every major expansion at Nigg over the past decade has created waves of indirect employment. With offshore wind, oil and gas decommissioning, and nuclear projects all requiring large‑scale port infrastructure, the demand for skilled labour is set to rise.
Maraen’s leadership has emphasised that the consolidation of three businesses into one integrated organisation allows them to invest with confidence, scale up operations, and offer more stable long‑term employment than fragmented ownership ever could.
A Signal to Global Energy Markets
The creation of Maraen is also a message to international investors. Scotland intends to be a serious player in the next phase of the energy transition. With Mitsui’s backing, the Port of Nigg is no longer just a regional asset. It is a globally connected hub with the financial muscle to compete for major contracts.
This matters because the global offshore wind market is entering a period of rapid expansion. Ports that can handle the largest turbines, cables, and foundations will win the lion’s share of work. Those that cannot will be left behind.
Maraen’s investment ensures that Nigg is firmly in the first category.
The Bigger Picture: Stability, Scale, and Strategic Advantage
For businesses across the North‑east, the benefits are clear:
More predictable project pipelines
Greater local content opportunities
A stronger regional supply chain
Increased inward investment
Long‑term employment stability
For Scotland, the message is even clearer. The country is building the infrastructure needed to anchor the energy transition at home rather than watching it drift overseas.
