Marlan Maritime Technology – Samantha Godfrey

The key research challenge here is to complement Marlan’s radar-based products for monitoring coastal change in the intertidal zone and below the water line by examining the use of still photographs and light reflectance to produce digital elevation models of beaches and maps of their evolving grain size. The primary environmental benefits of the integrated radar system are safer and more resource-efficient port and shipping operations and will contribute to Marlan’s new product development aimed at optimizing traffic management for fuel efficiency and targeting maintenance interventions such as routine pilotage and tug assistance, bathymetric surveys and dredging operations to maintain navigable channels. The introduction of the integrated radar system would aim to reduce dredging by at least 10%. 

This project also feeds into reducing carbon-intensive interventions for addressing erosion problems by intervening earlier and, thus, supporting nature-based solutions that work with coastal processes. There are many different types of seawall, depending on manufacturer, design and purpose. Recently competed Rossall sea defenses used over 1000 25 tonne precast concrete blocks.  These blocks alone equate to around 3,250 tonnes of CO2, without considering additional factors such as transportation or construction of the 270,000 tonne rock armour wall.
