  • Date: December 2009
  • Programme Duration: 3 months
  • Project Number: 2149
  • Value: £170,000
  • Client: New Walton Pier Company
  • Principal Contractor: New Walton Pier Company

The Challenge

The Haven Seajack 1 jack up barge was positioned as close as possible to the pier without disturbing the current supporting piles. A 50Tonne crawler crane was configured with a 1.5Tonne BSP drop hammer to install the new tubular sheet piles at specified points along the pier. A hanging work frame was also specially manufactured to provide operatives access to the underside of the pier in order to arry out minor repair works to the wooden joists, bents and beams.

The consistency for the seabed upon which to jack up was of poor quality in places and for a couple of occasions meant that the legs had to be removed by letting the rising tide lift the legs out of the mud.

Due to the condition of some of the old piles, due to be replaced, two disintegrated and fell into the sea during bad weather. Extra piles therefore had to be driven in order to complete the works.
