About This Project

CMP were contracted to install 50 tubular piles that provided the foundations for 3 new mooring dolphins. The piles were up to 40m meters long and 1.050m in diameter, driven up to 8 meters into the mudstone seabed.

CMP provided all the plant equipment, manpower and innovation to install these piles. A special frame was built to allow the piles to be installed at raking angles ranging from 1 in 4 to 1 in 2.5. The piles were initially driven into the alluvium with a crane suspended vibro-hammer, then back driven using CMPs 1146 HH14 piling hammer, which used a 14 tonne ram to provide up to 9000KN of driving force.

All the piles had to be installed using marine access due to the deteriorated condition of the existing pier. Piles were supplied from the shore by transport barges and a crane was stationed on a special modular piling barge designed specifically for the job.

Works Description
  • Tubular impact piling, with raker piles.
  • Modular crane barge provided with 180t crane lifting our 33 tonne hammer.
  • Installation of HZ 1080 (Arcelor) box piles using a special driving shoe.
  • Hire of piling barge and manpower to assist in concrete works.
  • Temporary works design and installation for piling frames.
