It cleans, inspects and removes steel structures on the Danish gas platform: Tyra the Robotic Crawler, a robot that eliminates the need for dangerous and expensive dives. To protect the robot against corrosion and wear during its work in the harsh North Sea, the engineers rely on high-performance polymers from the motion plastics specialist igus.
The next time you holiday in Denmark and turn on the gas stove, bear in mind: with a probability of 90 per cent, the gas comes from the Danish North Sea. Pumped from a platform called Tyra, which the company Total has been operating since 1987, located 200 kilometres west of the city of Esbjerg. But Tyra is in danger. Because the porous limestone layers under the seabed are diminishing. The seabed - and the gas platform - has sunk by over five metres in recent decades. This has brought the platform so close to the water that high waves in winter become a danger to employees. Therefore, Total has decided to rebuild the gas platform. Gas production has been discontinued until 2022. Construction work has been scheduled.
