P&O Cairnryan Berth 1 linkspan replacement


McLaughlin & Harvey has 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 & 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.
