According to directory reference data, offshore cranes typically have a maximum lifting capacity ranging from 5 to 50 metric tons. However, the actual capacity depends on the specific model and application, so it is essential to verify with the manufacturer.
Motion compensation systems, either active or passive, counteract vessel heave, pitch, and roll to maintain load stability. Active systems use sensors and actuators to adjust the crane's movements in real-time, while passive systems rely on accumulators and damping mechanisms. The reference accuracy is ±3 meters, but actual performance varies by model.
Offshore cranes may be designed to standards such as DNVGL-ST-0378, which provides guidelines for construction and safety. Other standards like ISO 4301-1 for lifting capacity and ISO 4302 for wind loading may also be relevant. Always confirm compliance with the manufacturer.
Directory reference data indicates an operating temperature range of -20 to 45 degrees Celsius and working wind speeds up to 20-30 meters per second. However, these are general ranges; specific models may have different limits, so verify with the supplier.
