Karrera & Gallanach – Slipway Extensions & New Breakwater

The Inner Hebridean island of Kerrera is accessed by ferry across the Sound of Kerrera from the slipway at Gallanach, 3 miles south of Oban. This project was to lengthen the slipways at both Gallanach and on Kerrera to removal tidal berthing constraints and to construct a breakwater on Kerrera to enable berthing under adverse weather conditions.

The contract was awarded on GL’s Alternative Design which offered a £200k saving on the conforming offer and the key elements comprised:

  • 15m sheet-piled extensions of the slipways, with
  • hardcore infill and pre-cast concrete deck.
  • A 40m x 6m sheet-piled cofferdam infilled andform the new breakwater
  • capped with pre-cast concrete deck sections to
  • 5,000cum dredging and 1,000t of rock armour

The site was serviced by the MV Misneach work boat which together with a barge delivered the piles, rock armour, craneage, excavators and other heavy plant across to Kerrera.
