Circular Economy - Lock gates

About this project

Start date:	02/03/2025
Project description:	The principal goal of this research is to identify and assess materials for lock gates that offer optimum performance, whilst minimising maintenance challenges. A Multi-Criteria Analysis (MCA) will be employed to evaluate materials based on durability, sustainability, cost, manufacturability and maintenance implications. The specific objectives are: Assess the current condition of lock gates on the Kennet & Avon Canal to identify key deterioration patterns and maintenance challenges. Evaluate alternative materials based on strength, longevity and resilience in a waterway environment. Examine best practices and alternative methods used across the industry to determine if applicable. Analyse maintenance implications, including repair frequency, ease of upkeep and lifecycle costs. Engage industry professionals to ensure that findings align with practical engineering and maintenance considerations. Provide evidence-based recommendations for material selection, balancing performance, cost and sustainability. Given the limited time frame, the exploratory nature of the research and potential for further projects based on this topic not all objectives may be met within this research project. Research Questions This research is guided by the following overarching question: Which materials are most suitable for lock gate construction, considering their durability, cost, sustainability and long-term maintenance requirements? To address this question, the following sub-questions will be examined: What are the primary causes of deterioration in existing lock gates on the Kennet & Avon Canal? What performance criteria should be used to assess alternative lock gate materials? How do different materials compare in terms of durability, environmental impact and compatibility with existing infrastructure? What are the maintenance and lifecycle cost implications of utilising alternative materials? How can alternative materials be effectively incorporated into current lock gate design and maintenance practices?
