Equinor is saving millions with the use of the underwater drone from Blueye.

May 25th Adressavisen wrote an article about how Equinor is reducing operational costs at the Kristin platform in the Norwegian Sea with the use of the underwater drone from Blueye. Equinor is using the drone to conduct frequent inspections of the seawater intake for the fire extinguishing system. The inlet is located at the bottom of the semi-sub pontoon. If the fire pumps are to start when the intake is full of marine growth, then there is a risk that the fire sprinkler nozzles will get clogged, which is very critical in case of a fire.

Equinor is just one of our customers that are using underwater drones for conducting frequent inspections themselves, which enables them to only hire external help when there is a job to be done. This reduces operational costs dramatically because they can reduce the use of large ships and ROVs. The article also states that Equinor has hunted costs for a long time. When the costs are high, the potential for savings is as well.

"We are continuously working with enhancements, and this case is one that we are really proud of." Says Terje Moum, Production Manager for the Kristin-field at Haltenbanken in the Norwegian Sea.

Blueye is proud to assist in cutting massive costs, while at the same time contributing to make the oil-industry a bit greener by reducing the use of large vessels.

The Blueye Pro provides ultra-sharp images that are transferred to a tablet or a mobile device. At the same time, it is possible to share the inspection with a remote team at shore via Microsoft Teams. This feature makes it possible to discuss the drone footage live in a meeting during the inspection, even if some team members are not physically present. The Platform Manager at Kristin, Narve Aske says that the drone does an excellent job, providing sharp videos that document the status of marine growth. Marine growth, or fouling, is a well-known problem for anyone that has a boat or some structure under the water, but when it cumulates at certain places, it can cause a hazard for the platform safety.

"Equinor saves one million NOK, every time we can spare the hire of a big offshore vessel for these types of inspections." Says Aske to Adressa.

Now it is the state of the marine growth that will trigger when it is necessary to hire a vessel for cleaning.

The Engineering magazine, Teknisk Ukeblad also published an article about Blueye and Equinor. In this article you can read about the challenges Equinor had when they first tried to inspect the seawater intake from the surface in a service boat. The waves gave too large motions and the drone got hard to control when the boat was drifting. Equinor then contacted Blueye and got valuable training and advice that made them succeed on their next attempt. Together we figured out that the best solution was to perform the inspection from the platform itself by lowering it down from the lifeboat deck at Kristin. A pulley was mounted in the ceiling which made it easier to lower the drone about 20 meters down to the sea surface.
