Marine Scotland has given its approval for Aberdeen Harbour Board’s planned £415million expansion into Nigg Bay.
The authority has granted two marine licences covering the construction and dredging operations for Nigg Bay, which lies to the south of the existing port.
The harbour board is still waiting for Transport Scotland to make a decision on the harbour revision order application which was submitted earlier this year.
Aberdeen City Council has already awarded planning permission in principle for the expansion.
Colin Parker, chief executive of Aberdeen Harbour Board, said: “The award of this statutory approval marks an important milestone in the Aberdeen Harbour expansion project and takes us one step closer to commencing construction of the new, expansive facilities.
“If final approval is given to the plans, the resulting development will help ensure the north-east of Scotland remains the home of globally significant supply chains, anchors decommissioning activity in Scotland, and puts Aberdeen city and shire on the map as a major cruise ship destination for many decades to come.
“I would like to thank Marine Scotland, Scottish Enterprise, my colleagues, our consultants and supporting organisations, who have worked tirelessly for several years to achieve this important goal.”
