ALE performed the Jacking of the Cutty Sark to create new exhibition space underneath the ship.
ALE implemented a 24-point jacking system using 100te climbing jacks, jacking beams and over 5000 hardwood timbers. The system used was designed and integrated to the clients lifting cradle steelwork inside and surrounding the ship. ALE worked closely with the client to develop the system and also conducted site visits and 3D survey models.
ALE also provided load monitoring equipment and software throughout the jacking process, this together with strain gauges on the ship’s structural members meant that the structural integrity could be confirmed throughout the process.
ALE positioned the lifting steelwork and carried out a trial lift prior to commencing. The ship was then jacked to the final height and permanent supports were put in place. ALE assisted with the adjustment of the permanent supports while lowering off the jacking system.
