Without a cap, we can't carry a water bottle in our bag. Without an elaborate tank lid system on cars, each bend in the road would become a danger - caps are often inconspicuous. It is hard to understand their true importance, unless they are missing. At a very large scale, the same is true for oil and gas production at sea: Technologically sophisticated insulation caps are needed to safely close and protect the wellhead at the bottom of the sea. Without them, oil and gas would emerge into the sea. Rarely is a cap subjected to conditions as difficult as these. A leading developer of systems for the oil & gas industry has evaluated and found that the Röchling material SUSTAPVDF can operate in these most demanding of conditions for producing their caps.
About a third of natural gas and oil worldwide is currently produced through offshore drilling. As many deposits in shallow waters are already depleted and the drilling and production technology is constantly improving, companies venture into ever deeper ocean depths for gas and oil production. Once a new oil or gas deposit is tapped, any oil production company is faced with two questions: How can we extract these resources quickly and reliably and how can we stop oil and gas from emerging into the sea during the extraction process? It is all about economic viability and safety. Engineers develop sophisticated technology to solve these problems.
Once a deposit is tapped, the wellhead cannot just be connected to a pipeline. To enable flow control and monitoring, the wellhead is connected with a "subsea tree" - a complex technical system consisting of valves, connections and other components. The subsea tree has a production opening to which the production pipe is connected. High demands are made of the engineers who develop this system. They have a great responsibility: A failure of the subsea tree would be very costly for the operating company; replacing defective components at the bottom of the sea would be complex. The worst case, however, would be oil and gas emerging into the sea. For these reasons, every detail is important in the planning stage. Economic viability and efficiency go hand in hand with safety. The insulation caps are particularly important for operating safety. They prevent oil and gas from emerging into the sea.
