The heaviest ever cylinder has been supplied by Bosch Rexroth to enable the smooth operation of a 130 meters tall derrick. Bosch Rexroth is known for its expertise in engineering in the world and the was called by the Government of China to provide with an innovative cylinder solution for a new piling barge.
The cylinder will not only provide stability but also help with the derrick’s smooth mobility and will be able to reach places of the seabed which has not been explored yet.
China is looking forward to develop more of offshore wind farms thereby increasing the available amount of green energy and also build bridges and harbor walls for protection and to connect.
Finding an area at sea that will suit the construction was difficult. To make this possible, the Government of China decided on the biggest piling barge of the world.
The barge is featured with a derrick that is 130 meter tall that can help reach the housing for concrete pillars into areas of the seabed that remains unexplored yet. This will enable the government to make more investment in offshore wind farms and green energy solutions and they will also be able to make more bridges so as to get along with the increasing population moving. It is important for the derrick to be stable in challenging conditions and be slowly moved with no sudden changes in speed. This will be possible with the cylinder and thus, Bosch Rexroth has been selected by the Chinese Government for it.
“They chose us because of our experience, and our trusted name,” says Rob Drabbe, Sales Manager for Large Cylinders at Bosch Rexroth. “We build cylinders like this all the time, so they knew they could rely on us to produce the equipment according to their specifications. Even though it’s going to help control such a large derrick, it’s not the biggest cylinder we’ve ever made. It is, however, the heaviest, at 146 tons.”
Consultation was also given by Bosch Rexroth at the procurement process relating to the initial plans for the cylinder’s construction.
“They had suggestions for coatings, seals and bearings,” adds Rob, “but we were able to show them that although the individual suggestions themselves were good, they didn’t work as well when combined in a single system. We were also able to show them our research and development facility, where they could talk to our engineers, which gave them even more confidence in Bosch Rexroth.”
The cylinder is so designed that it can withstand any condition and thus, operate smoothly and reliably. All the aspects from smoothness, corrosion protection, security factors to tribology has been taken care of in its construction. It is a robust and innovative cylinder which is coated with Enduroq to make it even more durable.
“The cylinder will be exposed for long periods,” concludes Rob, “so the construction had to have excellent corrosion resistance. We used our Enduroq laser welded stainless steel coating, as this is proven to be highly durable while offering the required smoothness. We’re looking forward to seeing how our cylinder can contribute to the success of this groundbreaking piling barge.”
