Plans for a significant investment exceeding £30 million into the Port of Nigg have received approval, coinciding with the unification of three prominent North-east Scotland energy businesses under the new Maraen brand.
Maraen emerges as an integrated energy infrastructure services provider, bringing together the capabilities of the Port of Nigg, Global Energy (Group), and Global Energy Services. The three entities will now operate under the names Maraen Port of Nigg, Maraen Fabrication, and Maraen Solutions, respectively. This rebranding follows the 2025 acquisition of these businesses by Mitsui & Co Europe Ltd and Mitsui OSK Lines Ltd, with Mitsui holding a 51% stake and Mitsui O.S.K. Lines (MOL) holding 49% of the companies.
Central to this strategic commitment is a final investment decision (FID) to develop a new heavy-duty quay and introduce roll-on/roll-off (Ro-Ro) capabilities at Maraen Port of Nigg. This substantial investment is projected to significantly enhance the port’s overall capacity and operational efficiency. It aims to improve inbound and outbound logistics for a diverse range of projects within the offshore wind sector and the broader energy industry. Furthermore, the upgrade is anticipated to attract new projects and clients to the facility, thereby stimulating additional investment and fostering job creation across the supply chain.
The development, which will span over 170,000 square feet (approximately 16,000 square metres), is partly funded by a £10 million grant from Highlands and Islands Enterprise (HIE). This grant forms a component of the Scottish Government’s wider commitment to invest up to £500 million over five years to strengthen Scotland’s offshore wind supply chain. The Scottish Government first announced this initiative in October 2023.
Yoshihiro Hayakawa, Chief Executive and Managing Director of Maraen, commented on the strategic move, stating: “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.”
Hayakawa further elaborated on the benefits of the consolidation: “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.”
He added: “The final investment decision on the Eastern Inner Dock Quay demonstrates that ambition, underlining our commitment to supporting complex, large-scale projects across oil & gas, offshore wind and nuclear, and positioning Maraen at the forefront of international energy infrastructure.”

Rory Gunn, Facilities Director at Maraen Port of Nigg, highlighted the impact of the investment on the port’s operations: “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.”
Gunn concluded: “By continuing to invest in our infrastructure, we are reinforcing our position as a leading UK energy port – trusted by developers to deliver the scale, efficiency and reliability required to support the energy industry now and into the future.”
