Bagged cement from Hanson UK's Ketton cement works has been shipped more than 9600 miles for use in the upgrade of Rothera Wharf in Antarctica.
The work is part of a long-term programme to modernise infrastructure at British Antarctic Survey’s Rothera Research Station to ensure its facilities continue to enable world-leading research.
Together with the commissioning of the RRS Sir David Attenborough, one of the most advanced polar research vessels in the world which is due to come into service later this year, the first phase of the modernisation work is to remove the old wharf at Rothera Point and replace it with a new one.
The work is being carried out by construction partner BAM Nuttall over two Antarctic summers (November to February) when temperatures generally range between 0 and 5°C and there is 24 hours of daylight.
The wharf upgrade will improve ship and boating operations and allow it to accommodate the RRS Sir David Attenborough as well as reduce manual handling cargo loading/unloading time.
Hanson said it worked with supply chain partners BAM Nuttall and civils specialist Keyline over a 14-month period of testing to perfect the technical specification of the cement, which needs to withstand the rigors of one of the harshest climates on Earth. Once the formulation was agreed we had just three weeks to produce and bag 125 tonnes to be shipped from Teesport docks.
Each of the 5000 25kg bags had to be vacuum sealed and double shrink wrapped onto heat-treated pallets to ensure Antarctica’s fragile ecosystem was not threatened by the transference of any harmful organisms or non-native species of plants or animals.
