Proper maintenance of subsea connectors significantly extends service life and prevents in-service failures. Follow these guidelines:

Before Each Deployment

• Inspect O-rings for cuts, compression set, or surface contamination; replace if in doubt
• Apply a thin film of approved O-ring lubricant (Parker Super-O-Lube or equivalent silicone grease)
• Inspect contact pins for corrosion, deformation, or contamination; clean with isopropyl alcohol
• Verify dummy plugs are fitted to all unused receptacles
• Confirm locking thread or bayonet coupling is fully engaged

After Each Deployment (Recovery from Seawater)

• Rinse connector with fresh water within 2 hours of recovery
• Inspect for biofouling; gently remove with soft brush -- do not use wire brushes on sealing faces
• Dry thoroughly before storage; store in clean dry environment with dummy plugs installed
• Record mating cycles in maintenance log; replace O-rings at manufacturer-recommended intervals

O-Ring Replacement Schedule

• Standard NBR O-rings: Replace every 12 months or 200 mating cycles, whichever comes first
• Viton O-rings: Replace every 18 months or 300 mating cycles
• Always replace O-rings after any suspected seal failure event
