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.

DBB system in instrument piping – a cost effective safety solution

DBB system in instrument piping – a cost effective safety solution (BA Series).

I remember very well when we started the development of our Double Block & Bleed Valve Series. We called it “VariAS-Blocks”. Production started 20 years ago, and we have made many improvements since there.

We based the design on the standard SHELL MESC SPE 77/165 (which the MESC SPE 77/170 superseded) and EEMUA 182.
