This bridge has the capability to advance all aspects of community engagement with infrastructure, clean energy innovation in tidal energy conversion, energy storage, structural and environmental impact, and social perception of our engineered environment. The TPM has a universal mounting bracket with a defined bolt pattern, to which turbine developers can mount their turbine. Instrumentation, wave measurement instrumentation, and a mobile data acquisition system was acquired to complement the instrumentation already available through the Living Bridge Project. Various instrumentation components including flow measurement The mooring system at Memorial Bridge consists of robust custom-designed pile guides which attach to 22-ft tall vertical guide posts on Pier #2, allowing the platform to travel vertically with changing water levels. The TDP was first deployed at Memorial Bridge under the NSF-funded “Living Bridge Project” with a 3.2m diameter commercial cross-flow turbine. Axial-flow and cross-flow marine hydrokinetic (MHK) turbines with diameters up to approximately 10 ft (3 m) can be deployed. Turbines are deployed through a moon pool via a turbine deployment mechanism. It uses 42” diameter HDPE pontoons for buoyancy and a galvanized structural steel frame for structural strength. A custom floating platform with nominal dimensions 50 ft x 20 ft (15 m x 6 m) was designed, fabricated and deployed. The bridge sensor network, information communication system and aesthetic lighting are powered by a tidal turbine (vertical-axis cross flow). Aesthetic lighting and social media is used to communicate relevant information from the bridge and environmental sensors, such as weather, tides and traffic to the local community. The information collected with these sensors is shared with researchers, bridge designers and the bridge owner, but also, where appropriate, with K-12 classrooms and the public. This bridge is instrumented with sensors that capture structural performance, traffic patterns, environmental conditions, the behavior of innovative bridge design elements and enable and promote community engagement. The Living Bridge crossing over a tidal estuary, is a living laboratory for researchers, engineers, future engineers and the general public.
