A collaboration combing the expertise of two Mersey Maritime members which saw a complex project delivered in time and on budget was the subject of a fascinating presentation at the July Face2Face networking breakfast.
Royal HaskoningDHV and Beech Group came together to manage the demolition of a set of passenger walkways, built more than 20 years ago, at the Port of Holyhead to make way for a new structure.
Owned and operated by Stena Line Ports, Holyhead handles a significant ro-ro and passenger traffic trade route between Ireland and the UK and Continental Europe. The work was focused on the demolition of the walkways linking terminal 3 with the terminal building.
Terminal 3 is where the Irish Ferries vessels berth and there are fours sailings a day 365 days a year. At the breakfast event, Jamie Gray from Royal HaskoningDHV told Mersey Maritime members that working around the sailings presented a huge logistical challenge.
“Any delays to the sailings either on the way in or on the way out would incur a cost of around 75,000 euros – so it is an expensive mistake if we can’t work within specific windows,” said Jamie.
Beech Group’s Chris Wainwright added: “When each boat left we would have a four-hour window to do what we needed to do. Key to the success of this project was sitting down with the clients to go over every detail.
“Everything had to be timed and every day we would have meetings on site to plan everything down to the last detail. It was a complicated job – not just because of the sailings but also because of potential disruption from changing weather conditions.”
The final lift was undertaken using a land based 750-tonne capacity crane reaching over 40 metres to lift a 34 metre span section of walkway weighing 35 tonnes.
Jamie added: “This operation was a great example of collaboration between Royal HaskoningDHV and Beech Group and this was an excellent operation.”
