We deployed the subsea structural monitoring system on a bridge pier in the Fraser River delta. The first month gave us enough data to assess both the hardware and the compliance workflow under the Navigable Waters Protection Act.
The sensor array itself performed as specified. The accelerometers and strain gauges returned consistent readings through tidal cycles and a minor freshet event. What stood out was the permitting support. The team at wiredfortheweteye handled the NWPA Section 5 review for the riverbed anchor points, including the fish habitat assessment and the sediment disturbance plan. That part alone saved us roughly three weeks of back-and-forth with Transport Canada.
One concrete detail: the telemetry unit lost signal twice during the first week. A firmware patch was pushed remotely within 48 hours, and the data gap was logged and recoverable. The calibration logs showed no drift beyond the expected 0.02% over the 30-day window.
For a first deployment, the system met the structural monitoring requirements we outlined. The NWPA compliance documentation was filed and accepted without revision requests. That is the metric that matters for our next phase.
