Work on the redevelopment of the busy Port of Felixstowe is well underway by Costain, with extensive marine work in progress. WM Plant Hire is using the 95 tonne CAT 375 and the 60 tonne CAT 345 long reach machines to remove demolition material and underwater obstructions and keep the deepwater channels clear for freight movements. A grapple attachment is being used for lifting the concrete and steel some 13 metres underwater.
