Description

A submerged concrete caisson, partially buried below seabed serving as a water intake facility, was to be instrumented to monitor potential settlements during its operation. To meet the objectives of the monitoring project, two Model 6160 MEMS Tiltmeters (located inside the caisson) were used to monitor any tilting and four Model 4420 Displacement Transducers (12.5 mm range) were installed on each pipe connection to measure longitudinal displacements; 2 on the stainless steel pipe and 2 at the stainless steel to concrete caisson pipe connection.
