Marine & offshore connectors are core components for electrical connection and signal transmission in marine and offshore environments, specially designed to resist seawater corrosion, salt fog, mold, vibration, and extreme temperature fluctuations. Our KMYD marine & offshore suitable connectors cover specific models such as M8, M12, M16, M23 connectors (M series), SP13, SD15, LD20, FD25 connectors (SP/SD/LD/FD series), marine standard connectors (DNV certified: LBCXCH, CXCH connectors), offshore customized connectors (VG 95234, VG 95328 compliant), and RF connectors (SMA, N-type connectors), all optimized for marine & offshore scenarios and widely applied in ships, offshore platforms, port equipment, and marine supporting systems, complying with strict industry standards and certification requirements.

1. Application Scenarios

Ships (passenger ships, cargo ships, warships, yachts): M series connectors (M12, M23 connectors) for on-board control system signal transmission and medium-power supply, LBCXCH, CXCH connectors for marine filtering and electromagnetic compatibility enhancement, and offshore customized connectors for main engine and power system stable power transmission, adapting to long-term seawater erosion and ship navigation vibration environments. 

Offshore platforms (oil and gas drilling platforms, wind power platforms): SP/SD/LD/FD series connectors (SP13, SD15 connectors) for offshore equipment control and signal integration, VG 95234 compliant connectors for power and signal dual-purpose transmission, and RF connectors (SMA, N-type connectors) for offshore communication and monitoring signal transmission, meeting IP68 high protection and anti-salt fog requirements. 

Port and terminal equipment (loading and unloading machinery, shore power facilities, navigation aids): M8 connectors for small sensor wiring and monitoring equipment connection, M16 connectors for shore power transmission and terminal control system connection, complying with GB/T 11918—2014 standard for shore power connector unification requirements. 

Marine supporting facilities (underwater detection equipment, marine observation stations): Underwater customized connectors (DNV certified) for underwater wet-mate photoelectric hybrid connection, and M12 connectors for underwater sensor signal transmission, with excellent waterproof sealing and pressure balance performance to adapt to deep-sea working conditions. 

2. Connector Structure & Forming Suggestions

Locking Structure: Screw lock or bayonet lock system is recommended to ensure stable connection and strong anti-vibration, anti-shock performance, avoiding loosening caused by ship navigation, wave impact, or offshore platform shaking, with vibration resistance up to 10Hz~2000Hz, acceleration 147m/s². 

Protection Level: IP67 or above for general marine scenarios; IP68 (submersible) for underwater or frequent seawater contact environments, and IP69K for high-pressure cleaning scenarios (port equipment), effectively preventing seawater, salt fog, and dust intrusion. 

Anti-misinsertion Design: Precise positioning structure and anti-misinsertion design are required to avoid circuit faults caused by wrong connection, ensuring compatibility between different connectors and improving maintenance efficiency in harsh marine environments. 

Structural Type: Single-core or multi-core modular design is adopted; reinforced double-wall shell structure is recommended for offshore high-pressure and high-corrosion scenarios, and pressure balance structure is added for underwater connectors to adapt to deep-sea pressure changes, with single-pole and multi-pole options to match different power and signal transmission needs.
