Harbour wall inspection partnered with LE34

Blue Atlas Robotics partnered with a leading Danish surveying service provider in order to inspect an ancient Danish harbour. 

Industry Partnership

The task, in collaboration with LE34, involved collecting high-quality data on quay facilities and conditions. The Danish Ministry of Defence’s Property Agency, which manages Christiansø and Frederiksø, requested the information in order to carry out a thorough investigation of deciding  the next steps for managing and maintaining the area.

Modern data necessary for ancient harbour walls

 The  survey target area has a special protected status, which means that any restorations must result with an end-product that exactly matches the start-point.
Rocks and other element can be moved but in the end, must be placed back.

In order to achieve this, extensive and accurate documentation of the current conditions is necessary, which is where Blue Atlas’ Sentinus robots, so that after any repairs, the visual condition can be returned exactly to as it was, down to small details.

Martin Steenberg, surveyor and expert in technical measurement, LE34 said:
“Preparation and coordination were a big player in this task. We had to make sure we had the right equipment with us once we were at Ertholmene. ”


In addition to data collection of the harbour, LE34 performed an above-water survey of the island’s rock contours for future planning of outlets for sewage treatment. LE34 surveyed on land with GPS to document existing conditions, and then sent the drone into the air to collect data for above-water 3D models and terrain models. In this way, the collaboration delivered a complete point cloud of the area, both above-water and below-water, which the Ministry of Defence’s Property Agency now has as comprehensive documentation.

FROM SENTINUS ROBOT

Visual results from the collaboration were clear and stable

A large-scale area was capturing during the duriation of the collaborative job. The footage from the 6 onboard cameras was clear and steady, revealing useful information for future maintainence decision-making. 

Results: detailed 3D models produced
