Offshore/Marine Active Heave Compensation Crane

Our Active Heave Compensation (AHC) cranes are engineered for offshore energy, cable-laying, marine construction. Their core AHC system offsets vessel heave caused by waves, ensuring precise, stable lifting even in ultra-deep waters or harsh sea states—critical for tasks like underwater cable deployment, heavy load landing, and subsea intervention.

Features

1. Active Heave Compensation Core System
– Main winch integrates AHC functionality to stabilize loads against vessel movement, enabling millimetric precision for subsea operations
– Optional fiber rope solution extends operational depth to 4,000+ meters, suitable for deep-sea energy projects.

2. Lightweight & High-Stability Design
– Optimized structure reduces weight while maintaining strength, improving vessel stability and deck load efficiency.
– Low-center-of-gravity component layout minimizes power consumption and operational risk.

3. Marine-Grade Corrosion Resistance & Extreme Adaptability
– Main structure uses high-strength low-alloy marine steel to resist saltwater corrosion.
– Withstands extreme temperatures (-40°C to +40°C) and humid environments; electrical components have IP66/IP67 protection ratings.

4. Intelligent Monitoring & Safety Protection
– Standard with condition monitoring systems (e.g., OnWatch Scout) for predictive maintenance, reducing unplanned downtime by 30%+.
– Multi-layer safety systems: overload protection, emergency stop buttons, and constant tension control.
– Supports remote operation from the bridge to reduce personnel exposure to offshore hazards.

5. Multi-Scenario Adaptability
– Power options: electric (for fixed platforms with shore power), diesel, or hydraulic.
– Optional add-ons: anti-collision systems, winches, and dynamic load calculators.
