Installation of a new geothermal heating system for Manchester Cathedral is currently being fast-tracked through use of a Marini drilling rig in order to meet the Christmas deadline for reopening the cathedral.
Ground source heat pump specialist Eco Friendly Installations is using the rig supplied by Skelair to carry out the radial drilling and pipe installations for the new heating system.
Work on the scheme must be completed by November but there was only a 12 week window in the overall redevelopment works for the heating work to be carried out. The scheme calls for 32 bores with a total length of 1.6km to be installed.
Ground conditions at the site have been challenging and a reamer and drag bit were needed to prevent the bores collapsing in the high groundwater and mudstones. The Marini rig has helped Eco to keep on track thanks to its small size and its manoeuvrability.
