Offshore

Large and complex deep-water installations require many hours of testing and data collection before they’re ready to operate at several thousand meters depth. Before these types of subsea structures can be placed offshore, hundreds of hours of shallow water testing must be reviewed. With underwater drones from Blueye, one can gather more information about the external condition during testing and before the structures are moved offshore.

Assessments on subsea structures with underwater drones

For several years, Siemens has together with other industrial partners, developed the world's first system for distribution of medium voltage based on pressure-compensated technology. This technology should be applicable to subsea fields as deep as 3000 meters.

Bjørn Rasch is the Product Lifecycle Manager at Siemens for the Subsea Power Grid. He explains that the power system will make it possible to distribute and control power supply to various customers working offshore. Pumps, compressors, pipeline heating and the like need electricity to operate. Before the Subsea Power Grid is ready to be lowered to a depth of 3000 meters, the power system must go through 3000 hours of testing in shallow water. By using Blueye underwater drones, Siemens were able to take a quick check on the external condition without emptying the dock for water.

Include colleagues on your inspections with the underwater drone

If you want to share the underwater inspection with colleagues or other onshore expertise, you can do so using both the Blueye Dive Buddy app and/or sharing the device screen on a larger external monitor.

Blueye Dive Buddy can be downloaded to other iOS and Android devices. You only need to connect to the same WiFi network as the drone and you’ll have the video stream on the drone on multiple devices in a flash. It’s also possible to share live video stream on a larger screen from the device running the Blueye Dive Buddy via an HDMI cable or a custom docking station.

Easy data processing after inspection

The video and picture capturing function on the drone makes it easy to document inspections. Once the inspection is complete, you can easily transfer them to a smartphone, tablet or PC with the Blueye app or the Blueye File Transfer.

Mounting additional equipment to the underwater drone

With the included action camera mount on the drone it is possible to place eg a GoPro camera which enable shooting at multiple angles. This gives you more room to film what you are looking for.
