Design and testing of scour protection for Adriatic LNG GBS
The Adriatic LNG terminal is a liquefied natural gas offshore terminal located about 17 km off the coast of Rovigo, Italy in the northern Adriatic, where the water depth is approximately 29 m. Scour protection was needed around the GBS and the mooring dolphins to prevent the bed material under them...
