Milford Haven Dock Construction

Background

McLaughlin & Harvey were appointed by the Port of Milford Haven for the £6m project to replace the lock gates linking the tidal estuary to the harbour and marina. This was the biggest investment of its kind to happen at Milford Haven Dock for more than half a century and aimed to significantly improve commerical and leisure craft access into and out of the harbour.

Scope of Works

WM Plant Hire was employed to assist in the removal and installation of the gates at the dock entrance which required some challenging underwater engineering, including the removal of concrete, cutting a new sill for the new gate to profile and level with the client brief of maintaining boat access at all times, and dealing with underwater obstructions.

Solution

The 85 tonne long reach excavator was supplied with an underwater breaker and rock cutting wheel attachment to break out existing structure and form a new sill to house the gate, working around the tides.  Using a GPS computer the operator had a computer image of the excavation allowing incredible accuracy and recording of the works carried out.
