Robot in place to contain oil spills
A new robot will be introduced at the Port of Gothenburg. Its task will be to deploy booms in the event of an oil spill. This new technology will result in more rapid and safer oil spill clearance at the Port of Gothenburg.
The Port of Gothenburg is the site of the largest energy port in Scandinavia. Crude oil is brought in and refined into petrol, diesel, asphalt and other products. Despite very strict safety stipulations, an accident could occur resulting in an oil spill.
“What is most important is that the oil is contained as quickly as possible to allow clearance to begin,” said Dan-Erik Andersson, Head of Operations at the Energy Port in Gothenburg.
For this purpose, the Port of Gothenburg has invested SEK 3.5 million in an automatic GPS-controlled boom. In the event of a spill, a member of staff at the Energy Port office presses a button on the wall. This activates a torpedo-like unmanned craft that travels around the dock towing a 400m-long boom. The automatic boom is made of plastic and is half a metre below water and 20cm above water.
“The robot tows the boom from one pier to another. It could be said that it forms a large bag in which the oil is collected. It has already been in operation once for testing and the results were good,” said Dan-Erik.
Compared with the customary approach – towing booms manually using boats – the automatic boom saves time. It takes approximately 10 minutes to contain a spill compared to half an hour when the booms are towed by boat.
“These are valuable minutes if we are to limit the spill as much as possible,” Dan-Erik Andersson stated.
Unique technology
It is the Gothenburg-based company SP Marine, together with the Port of Gothenburg, that has developed the automatic boom. The project commenced five years ago.
“It has taken a long time to adapt the robot to the conditions in the Göta Älv river and at the Energy Port and that is why it feels particularly gratifying now that development has been completed,” said Dan-Erik Andersson.
Similar robots are used in Malmö and are being developed in Stenungsund. Up to now this technology is unique to Sweden.
