Kennacraig Ferry Terminal Upgrade

CONTINUOUS OPERATION DURING CONSTRUCTION WAS ESSENTIAL FOR THE SUCCESS OF THIS PROJECT

Kennacraig Ferry Terminal is the mainland terminal supporting CalMac Ferries Ltd (CFL) sailings to Islay. It is situated in Loch Fyne. Caledonian Maritime Assets Ltd (CMAL) has procured a new vessel, the MV Finlaggan, to operate between Kennacraig and the Islay and, as a result, the existing ferry terminal needs to be upgraded. Scope of Works - To accommodate the new vessel, upgrade some of the existing infrastructure and effect repairs to accident damage a variety of works are required.

The works include- construction of a new open piled berthing dolphin/pier extension at the end of the existing pier, with steel walkway spanning back to the existing berthing dolphin. Dredging at the berths to suit the new vessel draught, relocation/provision of bollards to suit a revised mooring layout (including possible provision of concrete plinth supports); repairs to sheet pile walls, re-profiling of the existing concrete fixed ramp and replacement of damaged drainage channels in the marshalling area

ByrneLooby’s role during the construction stage was to provide design and construction supervision support on mooring & berthing upgrade, including design of temporary works to allow continued operation of the ferry terminal during construction.

The alternative design proposed by Byrne Looby Partners following a value engineering process included installation of large diameter hollow steel piles (1020mm with 27mm wall thickness) up to 27m long in deep deposits of compressible alluvium and rock socketed into metamorphic ‘country’ rock.
