A massive transformation is underway at one of Scotland’s most critical energy sites. The Port of Nigg is officially rebranding to Maraen and launching a £30 million expansion project to cement its status as a global leader in renewable energy. This major investment marks a new chapter for the Highlands and promises to accelerate the UK’s transition to green power.
Announced today, the project includes the construction of a new heavy-duty quay designed to handle the massive components required for offshore wind farms. Under the fresh leadership of Japanese owners Mitsui & Co. and Mitsui OSK Lines, the newly formed Maraen group is bringing together the port’s capabilities with Global Energy Group and Global Energy Services into a single, powerhouse entity.
A New Era Under Maraen Brand
The most visible change for the public is the new name. The Port of Nigg and its associated businesses have operated as separate entities for years, but they are now united under the banner of Maraen. The name is a thoughtful nod to the region’s heritage and future purpose. It combines “Mara,” the Gaelic word for “of the sea,” with “En” for energy. This rebranding follows the acquisition of the businesses last year by the Japanese trading and shipping giants.
Yoshihiro Hayakawa, the CEO and Managing Director of Maraen, described the move as a defining moment for the company. He emphasized that bringing these capabilities together strengthens their position to support complex, large-scale projects.
“The final investment decision on the Eastern Inner Dock Quay demonstrates that ambition,” Hayakawa said. “It underlines our commitment to supporting complex, large-scale projects across oil and gas, offshore wind and nuclear, and positioning Maraen at the forefront of international energy infrastructure.”
Heavy-Duty Quay to Power Green Energy
The £30 million investment is not just about a new logo. The core of this project is the construction of the Eastern Inner Dock Quay, a vital piece of infrastructure that will significantly increase the port’s capacity.
Key features of the new development include:
- Heavy-Duty Capacity: A reinforced quayside capable of bearing the immense weight of offshore wind turbines and generators.
- Ro-Ro Capability: A new Roll-on/Roll-off facility that allows heavy cargo to be driven directly onto ships, speeding up logistics.
- Expanded Space: The project adds approximately 16,000 square meters of operational area.
- Financial Support: The project is backed by a £10 million grant from Highlands and Islands Enterprise (HIE).
This infrastructure is essential because offshore wind turbines are growing larger every year. Ports need deeper water and stronger quays to handle the next generation of clean energy technology. With this upgrade, Maraen ensures that Scotland remains the go-to location for these massive logistical challenges.
Strategic Partnership with Sumitomo Electric
One of the main drivers for this expansion is the port’s neighbor. Sumitomo Electric is currently completing a state-of-the-art high-voltage cable factory right next to the port. This factory is set to begin operations later this year and will produce the critical cables needed to connect wind farms to the national grid.
The new quay will serve as the primary export point for these cables. Instead of transporting them by road, Sumitomo will be able to load miles of heavy cabling directly from their factory onto installation vessels docked at the new Maraen quay.
Jane Cooper, Deputy Chief Executive of RenewableUK, highlighted how this creates a perfect ecosystem for the industry.
“This Green Freeport is already an offshore wind hub,” Cooper explained. “The new quay will improve Sumitomo Electric’s capability to provide high-voltage cables for offshore wind farms at scale from its factory on the same site.”
Economic Boost for Highlands and Islands
This investment is a massive win for the local economy in the Highlands. The Port of Nigg has already supported the installation of over 4 GW of offshore wind capacity, but this expansion opens the door for even more work.
The site is part of the Inverness and Cromarty Firth Green Freeport, a special zone designed to attract business through tax incentives and simplified customs rules. By upgrading the port, Maraen is ensuring that the benefits of the Green Freeport are fully realized.
The ripple effects for the local community include:
- Job Creation: Construction of the quay and future operations will require skilled labor.
- Supply Chain Growth: Smaller local businesses will have opportunities to provide services to the expanded port.
- Global Attraction: A world-class port attracts private investment from other international companies looking for a base in Europe.
Cooper noted that upscaling the port will attract further private investment. She believes businesses operating side by side will create high-quality local jobs and provide essential components for the clean energy sector.
The construction of the new quay is set to begin soon, signaling a bright future where the Highlands remain at the beating heart of the global energy transition.
