Description

The existing western dolphin at Berth 6 at the Port of Dover was reported to move during berthing raising concern for the structural integrity of the portal frame and the long term operation for the berth. During an assessment period, the berth remained operational with regular measurements taken of the dolphins to ensure that movement at the structure remained within safe operational limits.

CGR was commissioned to assess the affects of the movement of the dolphin and to design suitable remedial works. The work undertaken by CGR included:

  • Structural assessment of the portal frame supporting the linkspan to determine any increased stresses due to lateral displacement of two of the frame legs
  • Review of the dolphin stability and proposal of suitable remedial works
  • Review of vessels using the berth and anticipated loadings
  • Design and specification for remedial works comprising the installation of new torsion arm fenders to reduce the imposed loads on the structure
  • Design and specification of new structural works to upgrade the foundation comprising new raker piles to the rear of the dolphin and associated reinforced concrete works.
  • Tender assessment and recommendations to Dover Harbour Board.
  • Technical support for Dover Harbour Board during the construction phase to deal with any technical queries from site.
  • Technical review of the new Torsion arm fender calculations and details.
