Teesport Berth Reconstruction Phase 1 and 2

Title: Teesport Phases I & 2

Client: McLaughlin & Harvey Ltd

Solutions: Marine based Rotary Bored Piles, relief drilling to sheet piles and and Design and Installation of Anchors for storm bollards

The piling contracts for Phases 1 & 2 comprised the installation of 450 no. rotary bored piles with permanent steel casings up to 1050mm diameter to support the new quay construction. 

Quinn Piling mobilised three rotary piling rigs and worked shifts for much of the project to improve on the main contractors demanding programme, achieving six piles per day. At each pile location on the existing quay deck, a 1360mm diameter hole was bored through the existing 4ft thick reinforced concrete deck with a bespoke core-barrel fitted with heavy duty tungsten-carbide teeth. Once the existing deck was cored, a permanent steel casing was inserted and drilled through the existing rock armour below  and into the bedrock. A further 15m rock-socket was bored to construct the pile which had total depths of up to 36.5m.

The piling works were completed well ahead of program and the sequence was co-ordinated with the main contractor to enable the demolition and new quay slab construction activities to follow close behind the rigs and progress concurrently. The total length of quay reconstructed was approximately 550 metres in under two years.

The anchor package involved the design, installation and testing of 63.5mm diameter double corrosion protection anchors, drilled to depths of up to 60m. The 110 ton high-capacity anchors resist forces from large storm bollards used by the port to secure large cargo ships during high winds. There were five storm bollards in total with four anchors in each bollard foundation.
