Remarkable progress has taken place at the Aberdeen Harbour Expansion Project in 2021, and all marine-based activities at the project are now complete. Construction of two critical structures - the South Breawkater and the Crown Wall - has finished, and all 22 caissons are in place. The last of the 9,000 accropodes has been made, and the remaining accropodes will be placed along the North Breakwater in the coming weeks. In 2022, work will continue to build the quaysides, with the provision of service trenches and other utilities.
