The consequent outcomes are expected to match the main objective of Defraís BREW program, i.e. to return additional landfill tax receipts to businesses in a way that supports them in working to improve their resource efficiency and waste management. The work is being carried out by Dr. Xiu-Tian Yan and Mr. Wendan Wang of Department of Design, Manufacture and Engineering Management, The University of Strathclyde. Two distinct products from two separate heavy industry companies in UK have been selected for the case studies i.e. the electric gasmizer diver gas recovery system from Divex and the cooling water pump from Weir Service Engineering. The electric gasmizer diver gas recovery system is one crucial part of deep-sea diving systems for dedicated diving support vessels and platforms. Its purpose is to recover gas mixtures breathed by divers, re-process them and deliver them into the supply system. Typical applications include off-shore oil and gas exploration, submarine rescue and so on.The main issue in upgrading the gasmizer system is that mechanical functions are still fulfilled by the original design which was developed nearly twenty years ago. Although there have been many advances in technology from computers to automatic control and communication systems, they have not been applied to upgrade these systems. Although the systems in service require technological upgrade, their mechanical components are still in good condition, and they should therefore be upgraded and reused to save the cost and energy of building a complete new system. Unfortunately, not much consideration was given to modular design during their initial development. As a consequence of this some components are now proving too difficult to upgrade and reuse. It is important to introduce a credible design methodology as soon as possible to lead the system to be more modular. The team has so far refined the proposed modular design methodology for product upgrade and reuse, and applied this methodology into the gasmizer system. They are currently investigating the upgrading requirements of the cooling water pump from Weir Service Engineering. The feasibility of the proposed design methodology will be concluded by validating the solutions resulting from its application on these two products.
