Net-Zero Bathymetric survey in Amsterdam (Deep Green)
Project summary
A lot of construction is taking place around Amsterdam Central Station. Building materials are often transported to the construction sites by water. For a project at the Oosterdok, a floating pontoon with maximum load capacity had to reach the construction site, without getting stuck on the bottom. To ensure this was possible, contractor Mammoet engaged Deep Green for an emission-free survey.
EMISSION-FREE SURVEY WITH DEEP GREEN PURPLE
Since the Oosterdok in Amsterdam is part of an emission-free zone where only electric vessels are now allowed, this was a perfect job for Deep Green. Our surveyors developed a plan for the survey area, prepared the necessary equipment, and launched the 100% electric vessel Deep Green Purple in Amsterdam-Noord. After crossing the IJ, we were able to map the area.
THE CHALLENGES OF AMSTERDAM’S WATERS
Even though the location was easily accessible, our team encountered several challenges. The survey area included water beneath a bridge - and under bridges, the GPS signal drops out. Therefore, we used an INS (Inertial Navigation System) motion sensor to collect accurate data. We also had to navigate through the busy water traffic around Amsterdam Central Station. Since we occasionally had to wait for a passing tour boat or other vessels, data collection took a bit longer than expected.
In the end, we successfully delivered the data to the client on time. After analyzing the results, it was confirmed that the pontoon could safely reach the construction site without any issues.
