This PhD project investigates strategies to protect underwater infrastructure, such as subsea power cables, from the impacts of submarine landslides—a growing concern as the UK expands its offshore wind capacity. Submarine landslides, which displace large volumes of sediment across the seafloor, pose serious risks to subsea cables, often causing costly damage and service disruptions.

By using a geotechnical centrifuge—a specialised testing setup that replicates gravitational forces at scale—this project will recreate landslide impacts in a controlled environment to assess how different types of flows affect cable resilience.

The research will focus on two primary flow types, cohesive and granular, each representing different real-world landslide behaviours and presenting unique challenges for subsea infrastructure. Cohesive flows, typically denser and slower, exert sustained pressures, while granular flows, more dynamic, deliver high-energy impacts. By experimentally modelling these scenarios, this study aims to understand the fundamental behiour, which inform the design of infrastructure better suited to varied seabed conditions. In doing so, it will address essential knowledge gaps and support the renewable energy and energy security goals of the UK.
