Project Objectives/Outcomes

The works comprised three excavations for a Dump Tank and two Oil Interceptors. The Dump Tank was the larger element with excavation dimensions of 20.65m x 11.05m with an excavated depth of 5.735m.  The  Oil  Interceptors  excavations were  8.65m  x  3.85m  and  9.85m  x  3.85m  on plan dimension and 3.365m and 3.77m  deep respectively. The excavations were supported using sheet piles. The Dump Tank were braced using hydraulic frames and the Oil Interceptors were not propped.

Our Role

John Sisk & Son appointed Trench Control to design and install ground support measures to facilitate the construction of three service tanks for the proposed Western Link Interconnector Project.

Commenting on the works, Sisk’s design manager Brian Dillon said the following: “We’ve worked with Trench Control on the Flintshire Bridge Converter Station Project and we’ve found them to be very knowledgeable both in the planning and the execution of their works”
