Maraen has announced plans for more than £30 million of investment at the Port of Nigg following the rebranding of three Scottish energy businesses under a single group.
The company said it brings together Port of Nigg, Global Energy (Group) and Global Energy Services after their acquisition by Mitsui & Co. Europe Ltd. and Mitsui O.S.K. Lines Ltd. in 2025.
Maraen added that a final investment decision has been taken to develop a new heavy-duty quay and roll-on roll-off capability at the port.
The investment will enhance capacity to support offshore wind and wider energy projects while attracting new customers and supply chain activity.
The Port of Nigg has already supported the deployment of more than 4GW of offshore wind capacity and will strengthen its role as a strategic hub.
The new quay will also provide a dedicated load-out and export facility for high voltage cables from the adjacent Sumitomo Electric HVDC cable facility.
“This is a defining moment for our business. Our new name, ‘Maraen’ – combining ‘Mara’, the Gaelic word for ‘of the sea’, and ‘En’ for energy – reflects our heritage and our ambition to shape the future of energy across multiple sectors.” said Yoshihiro Hayakawa, chief executive and managing director of Maraen.
“Bringing our capabilities together under one brand strengthens our position as an integrated energy infrastructure solutions provider, allowing us to deliver at a greater scale and invest with confidence in long-term growth for our customers, communities and wider stakeholders.”
“This targeted investment will bolster Maraen Port of Nigg, increasing both our capacity and capability to support large-scale energy projects. The new quay will boost our ability to handle complex, simultaneous operations and meet the growing demands from the energy industry.” said Rory Gunn, facilities director at Maraen Port of Nigg.
Construction of the 16,000 square metre development will begin soon following planning consent and a marine licence, supported by a £10 million grant from Highlands and Islands Enterprise.
Commenting on the announcement by Maraen that it has taken a final investment decision to develop a new heavy-duty quay and ‘roll-on roll-off’ facility at the Port of Nigg in Scotland, RenewableUK’s Deputy Chief Executive Jane Cooper said:
“This decision to invest £30m in the Port of Nigg will transform it into an even bigger base to support and accelerate the deployment of offshore wind here and across the world. The announcement highlights the scale of the opportunity for the UK to expand our offshore wind supply chain, driving the regeneration of ports and establishing them as leading centres of clean energy excellence.
“This Green Freeport is already an offshore wind hub, and 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. Upscaling the port will attract further private investment from other supply chain companies, with businesses operating side by side to provide components and services for the clean energy sector and create high-quality local jobs”.
