Oceanographic & Environmental Monitoring
Connectors for Oceanographic and Environmental Monitoring Systems
Oceanographic instruments -- CTD sensors, ADCP current profilers, sediment traps, landers, and mooring arrays -- operate for months to years in the deep ocean without maintenance. The connectors that interconnect these systems must provide zero-leakage reliability over multi-year deployments, often at full ocean depth (6,000+ m). RV Power Group manufactures subsea connectors engineered specifically for long-duration, unattended oceanographic deployments.
Oceanographic Deployment Challenges
| Challenge | RV Power Group Response |
|---|---|
| 12-24 month unattended deployment | Dual O-ring seals, 100% pre-deployment pressure test |
| Full ocean depth (6,000+ m) | Rated to 7,000 m; titanium shell option |
| Biofouling over multi-year deployment | 316L SS / titanium shells resist marine growth adhesion |
| Low power budget (battery-operated) | Gold contacts with <5 mO resistance minimize I2R losses |
| Multi-drop mooring topology | Multi-pin Circular connectors for branching mooring configurations |
| CTD / chemical sensor cables | Compatible cable assemblies in PU, Neoprene, or XLPE jacket |
