P&O Cairnryan Berth 1 linkspan replacement


McLaughlin & Harvey Civil Engineering have won this prestigious design and build contract, with project partners TTS as linkspan designer and fabricator and Royal Haskoning as Marine Structures Designer. The project began on-site in January 2013, and to date works are progressing well.

With the existing Berth 1 linkspan at Cairnryan coming to the end of its operational life, P&O’s requirement is primarily to improve the Port facility and future-proof the operations at Cairnryan, reducing turnaround times for vessels and increasing reliability of the linkspan.

The aim of this scheme is therefore to design and build a new double deck Ro-Ro floating linkspan which shall cater for a wider range of vessels, with reduced operational and maintenance requirements.

The first task on this project was to construct a new access directly off the A77 road. Once complete, works then began on reclamation.  Over the course of 7 weeks, we imported and placed 80,000t of cobble fill out into the existing Loch at a rate of 1500-2000t/day.

We then constructed temporary piling and crane platforms, in order to complete the permanent pile installations. Rotary bored pile installation and revetment construction is on-going at present.

With the berth remaining fully operational throughout the duration of the contract, disruption to the existing Berth 1 ferry operations have to be kept to a minimum.  One 48hr shut-down period to the existing service will be permitted during November 2013, in order to switch the existing berthing line to the realigned berth. All on-shore reclamation works including bankseat construction, marine pile installation, drainage, CCTV, service installations, maintenance building and surfacing works shall be complete prior to this.
