Case Study – Pembroke Dock Marina Project

Earlier this year ABI Equipment Ltd supplied a Delmag RH34 drilling rig to BAM Nuttall for use on the Pembroke Dock Marina Project.  This major infrastructure project is part of the £1.3 billion Swansea Bay City Deal which is developing a world-class centre fro marine engineering and is set to create around 1,800 highly skilled jobs, as well as generating extensive opportunities for the local supply chain.

The work being undertaken includes upgrading key elements of the port’s infrastructure and the construction of new slipways and pontoons.  These will give access to the new floating offshore wind farm planned for the Celtic Sea.  The new slipway will allow for the easy launch and recovery of marine vessels and the pontoons will enable the floating offshore wind industry to operate more effectively.

The Delmag RH34 piling rig, working from a jack-up barge, was fitted with a drill axis extension kit to increase reach and clearance in front of the leader mast. Working through a guide frame and large diameter casing the rig drilled Ø1500mm x 8m deep sockets into hard limestone rock to depths of 17m.  Once formed, the Ø1220mm pontoon piles were carefully placed and grouted within extremely tight tolerances.

It was an interesting and challenging project – read the full case study on our website here  Case Studies page.
