  • U-534 Project

    In 2008 Holemasters were contacted by MerseyTravel to undertake one of its most ambitious projects to date, to slice up an old German U boat, nemesis of Allied ships during World War Two.

    The boat sunk in 1945, was recovered from the Kattegat between Denmark and Sweden in 1993. It was the brought to Liverpool by MerseyTravel to turn it into a tourist attraction at the Woodside Ferry Terminal.

  • Windscale Chimney Decommissioning

    The Windscale chimneys have been a major part of the Sellafield skyline since the 1940s and work to decommission the filter gallery on top of the last remaining chimney is now half way there.

    Sellafield Ltd is demolishing the 530 tonne filter gallery before the chimney itself can be dismantled. This chimney worked as a ventilation shaft for Windscale Pile One which caught fire in 1957 and the filters fitted at the top of the chimney prevented much of the radioactive contamination escaping to the local area.
