Case Study: Jacket Stabilisation

Case Study: Jacket Stabilisation

Seabed scour had occurred at the platform and hydrodynamic loading was causing the jacket to move about the driven piles. This movement could be felt in the steel platform and topside. The movement was expected to reduce the life of the jacket had it not been rectified.

The jacket has six main legs and is fixed to the seabed by one pile driven through each corner leg. The jacket was secured to the driven piles by crown shims welded at the top of each corner leg. The structural integrity of the jacket was dependant on a strong welded crown shim connection and the mudmats resting on the seabed.
