Marine Development
Marine Development (Glasgow) Ltd., established in Scotland in 1972, developed the linkspan for over 30 years. They pioneered integral tank, submerged tank, and mobile linkspans under the direction of John Rose. These semi-buoyant ship-to-shore bridges minimise engineering infrastructure requirements and were originally designed a cheap and simple means of using ro-ro ferries in the Western Isles of Scotland, but later found wider applications.
