How a natural gas terminal meets 99% supply availability with DBB valves

Natural gas terminal meets 99% supply availability with DBB valves.

The cease of natural gas imports from Russia forced Germany to switch from energy providers. Since then, Norway has grabbed the number one spot as the main supplier. To secure reliable gas transfer and distribution, all facilities within the circuit must be at peak capacity. One of those facilities is a Gassco plant located in northern Germany. The revamped Emden natural gas terminal kicked off operations in 2016 with the operative premise of providing an availability delivery rate above 99%. Since the start-up the plant did not reach its potential due to a leakage problem at the shut-off valves. Together with the customer, we set about working out a solution to achieve the high requirement of 99% availability. Here’s how we helped Gassco get to the promised target.

How to isolate a process line from process instrument with a DBB valve

Different methods to isolate process line from process instrument.

Block and Bleed and Double Block & Bleed isolation systems are used in process instrumentation to isolate your instrument from the main process line. The isolation valve(s) stop the flow from the upstream, while the bleed valve removes any pressure or residual product that remains in the downstream section or in the section between the two valves.

Use of block and bleed valves is mandatory in many industrial processes for isolating the measuring instrument from the process line. This allows maintenance work to be performed on the instrumentation without the need to shut down the entire operation. There are two approaches to the installation of a block and bleed or a double block and bleed setup.
