312 valves, one shutdown
Servicing every valve on a shallow-water platform during a 19-day shutdown, with the Onne workshop running day and night.
Shallow water, 2025
Platform shutdowns are expensive, so every hour counts. We surveyed every valve two months ahead and tagged each one with a QR code linked to its history, spares and procedure.
During the shutdown, valves that could be serviced in place were done by three offshore crews. The rest came to the Onne workshop by supply vessel, were stripped, lapped, rebuilt and pressure tested, and went back out within 48 hours.
The client received a digital record for every valve: photographs before and after, test charts and the technician’s name.

E4What we learned
- 01Plan around the window
The schedule was built backwards from the date access would close, not forwards from mobilisation.
- 02Move the camp with the work
Less travel means more working hours and fewer boat incidents.
- 03Inspect the same day
Same-day inspection means a repair is a short job, not a crisis.
