Digital Twin Technology in Lighthouse Maintenance

Digital twin technology — the creation of an accurate virtual replica of a physical structure — is transforming the way lighthouse maintenance is planned and executed. By combining drone photogrammetry and laser scanning, engineers can identify problems months before they would be visible to the naked eye.

A traditional inspection of an offshore lighthouse requires a crew vessel and several days of weather-dependent access windows. A digital twin inspection can be completed remotely in a matter of hours.
