    Case Study: SCM Recovery Project Background In 2023, a Dril-Quip Subsea Control Module (SCM) from the Catcher Field’s CI1 location was recovered following reports of a hydraulic fluid leak. The intervention confirmed that hydraulic fluid was leaking from the gas end valve assembly of one of the three low-pressure (LP) accumulators installed on the SCM. The faulty SCM was returned to Proserv’s Great Yarmouth facility for detailed inspection and root cause analysis. Findings
  • The gas end valve was fabricated from low-grade stainless steel (SS 304), which is not corrosion-resistant in subsea environments
  • The component was not connected to the SCM’s cathodic protection system, leaving it vulnerable to galvanic corrosion
  • Corrosion was confirmed as the likely failure mechanism
  • The associated accumulator bladder was also found to be damaged; however, it remains unclear whether this failure preceded or resulted from the gas end valve issue
    •  Corrective Action Plan Upon identifying the issue, Harbour Energy initiated a campaign to recover and upgrade all 24 SCMs in the field. The key upgrades include:
  • Replacing the LP accumulator gas end valve assemblies with corrosion-resistant SS 316 components
  • Installing earth bonding to ensure future protection via cathodic protection
  • Refurbishing two SCMs (Unit 10 and 14) at Proserv’s Great Yarmouth facility to serve as operational spares
    •  Scope of Work - Onshore (Proserv Great Yarmouth)
  • Development of new test procedures and engineering drawings
  • Load testing and replacement of affected components, including:
    • Gas end valve assemblies
    • LP accumulators
    • Filter assemblies
  • Removal of all calcifications from anodes to prevent system contamination
  • Cleaning of all accessible external stainless steel components
  • Assembly of upgraded SCM housing and completion of all required testing
    •  Scope of Work - Offshore (Proserv Scope)
  • Removal of SCM side panels and top plates
  • Initial visual inspection of internals
  • Secondary wash down with panels removed
  • Detailed inspection and assessment of LP accumulator gas end valves
  • Pre-charge checks and top-up of LP / HP accumulators
  • Removal and replacement of affected gas end valve assemblies
  • SCM pre-deployment checks following retrofit
    •  Results & Observations
  • 12 out of 14 SCMs (86%) recovered exhibited significant corrosion of the LP accumulator pre-charge components
  • SCM 18 (BP3) was quarantined after an unsuccessful recovery attempt by vessel contractor, where it fell to the seabed. It was replaced offshore by SCM 10
  • SCM 22 was recovered and found to have a pre-fitted earth strap. Dril-Quip confirmed that SCMs 22 and 20 had previously been upgraded to the latest revision
  • SCM 11 was upgraded onshore at Proserv to the latest specification
  • SCM 19 (CP4) was successfully retrieved and returned onshore for rework. It was replaced offshore by SCM 14
    •  Conclusion The campaign has effectively identified and mitigated a systemic corrosion risk to subsea infrastructure caused by suboptimal material selection and insufficient cathodic protection. The proactive retrofit program significantly enhances system integrity and operational reliability across the Catcher field.
