|Situation:||4 Parallel single valve isolations|
|Result:||Guaranteeing safe work environment with double block & vacuum|
Recently there was a maintenance requirement on the Neptune Energy L10-A bridge-linked complex in the Dutch sector of the North Sea. On the L10-AD platform a compressor barrel had to be exchanged. There were 4 isolation points in parallel, all single valves with a connection possible to the body cavities of these valves.
With our Valvetight DBB-SAVER solution a tight shut-off isolation was 100% guaranteed. We created, maintained, controlled and monitored the vacuum in all four cavities simultaneuously, with just a single DBB-SAVER set-up. A Liquid KO vessel was used upstream of our DBB0SAVER vacuum unit. The work could be safely executed without delays, further shutdowns or depressurization of adjecent systems.
We thank Neptune Energy for their trust and great collaboration and welcome atmosphere on board!
