Stena Line Ports

SAFE NAVIGATION OF VESSELS IN THE PORT WAS KEY FOR THIS PROJECT'S SUCCESS

The project involves the construction of a green field ferry port “Loch Ryan Port”, which will substitute the existing Stena Terminal in Stranraer Port, located only 10 kilometres away from the proposed new port, and will accommodate Stena Line’s existing ferry service between Stranraer and Belfast.

The land based site is approximately 115,000m2 in area. Dredging of approximately 796,000m3 will be required to allow the safe navigation of vessels to/from the port and to provide the necessary material to allow ‘reclamation’ of the site.

The main components of the port design which ByrneLooby was responsible for was all piling works mainly relating to the marine elements of the project. ByrneLooby’s role services included design of rotary bored piles for two-berth RO/RO finger jetty, bankseat, temporary reaction anchors for test piles and axial pile design for structures. Ground conditions comprise 5m of made ground (reclaimed land) over 6m of loose estuarine sand, overlying some 30m of very soft compressible estuarine alluvium.

Competent termination stratum for piled foundations was either firm clay or gravel at depth. Piles consisted of up to 40m long 900mm diameter rotary bored piles with sacrificial casing through compressible soils.
