 Post operational and decommissioning work draws heavily on the wide range of skills and design acquired gathered over many years at Workington. Once a process has been proven in terms of costs, efficiency and programme, the technology can be transferred and further developed for future decommissioning tasks. A staged and phased approach is undertaken to each task and not until all parties have bought into the proposed methodology is the design and processes passed for production. Projects include:
B29 Re-Equipment Corus Process Engineering designed and manufactured equipment for this decommissioning project. The blind wash skip-cleaning facility consisted of a galvanised steel structure supported on an underwater bogie, underwater skip support and location frame and submersible pump with associated valve and pipework feeding a spray ring to clean the outer skip walls. Underwater cameras, lights and skip detectors were provided to improve operability of systems over a varying range of pond water (visibility) conditions. Each decanning and withdrawal bay was fitted with an underwater trolley system comprising new tracks, stainless steel trolley with underwater motor gear unit powered from an above water 'contained' reeling drum feeding cable via an underwater swivel pulley system. Underwater cameras, lights and skip detectors were provided to aid operator control. | |
