A passing-valve campaign closed with a client completion certificate

The valve and its duty

A pipeline installation in the southern region engaged us to arrest passing valves.

Passing valves on a petroleum pipeline weaken every isolation the operator depends on.

Arresting passing early also protects the pipeline's planned maintenance isolations later.

The committee purchase covered cleaner, sealant and services to arrest passing valves.

One party carried both parts, so no gap opened between product and application.

The installation wanted the whole set arrested in one planned campaign, not piecemeal visits.

Cleaner and sealant work as a pair across a campaign of mixed valve conditions.

The intervention

1. Our team put in six man-days on site through the campaign.
2. Cleaner came first on each valve, then sealant, following the graded route.
3. The client's own engineer wrote the field report on the work.

Cleaning before sealing lets each valve show whether contamination or damage drives the passing.

Sealant then follows only where the cleaned valve still needs it.

Six man-days on site kept momentum and let each valve be followed up.

A campaign format treats every listed valve inside one mobilisation.

The outcome and the record

The client issued a formal completion certificate for the campaign.

Both the field report and the certificate were the client's own documents.

A completion certificate is the client's statement that the scope was delivered.

The field report likewise came from the client's engineer, not from our team.

Together the two documents close the campaign with independent evidence.

Payment for the completed campaign followed the client's certificate in due course.

Client-authored records carry more weight than any claim a vendor writes about itself.

That is why our cases quote written confirmations rather than internal summaries.

Written closure like this is what we aim for on every campaign.
