The current methods of secondary docking positions and block removals are reviewed and a new approach using jacks is presented. The development of an initial version of the new approach is described. This covers the elements of removal and replacement concept, general arrangement, limitations of the existing equipment, removal equipment and wood compression properties. These aspects are then brought together to create the requirements for the jacks. Operational experience on the first three dockings using the initial version at Babcock’s Devonport site is discussed. The limitations of the initial approach are quantified and a fully developed solution which allows 100% block removal is presented. The paper concludes that the new approach of using jack-able super blocks provides benefits to both the shipyard and the ship operator. This project has been achieved through new research and the application of a sound knowledge of engineering and tolerances. The intellectual property of the paper is the subject of a pending patent.
