DELIVERING RESULTS THAT MATTER

Whether you may be looking to work with Savante as part of a routine integrity maintenance campaign; or to provide critical assessment in response to the discovery of an emergent risk Savante only delivers the highest quality materials and data.  


We have summarised a selection of case studies; achieved utilising our laser modules to assess pipelines, mooring chain systems, well-heads and many other subsea assets below to underline our successes and commitment to helping deliver the right data so the vest decisions can be made.

Client A

United States IOC

Summary:

During a routine annual inspection of a subsea field, our client detected an anomaly on the internal sealing surface of a subsea wellhead.

With the client unable to qualify the wellhead as safe to operate; we were asked to deploy a bespoke laser deployment and measurement solution to the gulf and collect sufficient evidence; this guiding the clients future operations.  Without confirmation of an effective dual-sealing barrier system at the wellhead; local regulations prevented the client from deploying a BOP.

This video presents an overview into the operational use of our subsea laser scanner in confirming the integrity of a subsea wellhead. The integrity of the wellhead was questioned after a series of digital stills images were recorded of a number of indications located within the wellhead using an ROV and a video camera.

Savante Technical Assistance Summary:

FRAQ - FIRST RESPONSE ANOMALY QUALIFICATION

  • Laser and camera deployed.
  • Presence of a gouge confirmed.

SRAV - SECOND RESPONSE ANOMALY VISUALISATION

  • Laser scanner deployed.
  • Operations completed in 12 seconds.
  • 3D surface model of anomaly rendered.
  • Measurements to precision 0.065mm recorded over width and depth of gouge

Outcome:

Savante detected and confirmed the presence of an integrity-compromising defect under guidance from the wellhead manufacturer.  The client ceased all further operations until a repair remedy had been implemented. Whilst expensive in terms of delaying the start of production to the wellhead, the clients operational safety record was never compromised and their prudence prevented the potential for any environmental incident.

 

Client B

West African NOC

Summary: 

During biannual mooring system inspection campaign, FPSO operator reported significant wear on 105mm studded chain links beneath the splash zone.

Client was unable to quantitatively confirm the condition of the mooring links and assure the continued safe operation of the installation.


Savante Technical Assistance

 

FRAQ - FIRST RESPONSE ANOMALY QUALIFICATION

  • Moved straight to SRAV

SRAV - SECOND RESPONSE ANOMALY VISUALISATION

  • Laser scanner deployed.
  • Anomalies scanned with WROV in free-flight.

Outcome:

Confirmed areas of wear loss and chain link elongation.  Oil operator has developed a progressive inspection program to monitor for further chain degradation.  Chain replacement program created.

Operational safety never compromised.  Integrity and company brand protected.
