The Norsafe NDSC-25MW21 slewing davit is specifically designed for safe and efficient launch and retrieval of fast rescue boats and life rafts. It is intended for long term, reliable operation in harsh and hazardous marine and offshore environments. The davit system is designed in accordance with latest Solas and IMO requirements.
The davit consists of a mechanical slewing jib and an electric driven winch with single wire fall. Slewing and dead ship slewing functions are driven by a small hydraulic power pack. The hydraulic system is equipped with a stored power unit - which allows full operation of the davit in “dead ship” conditions.
The system provides:
Hoisting of the loaded rescue boat by electric motor
Gravity lowering of the loaded rescue boat independent of external power supply
Dead ship slewing of the rescue boat by the nitrogen accumulator installed on the davit arm
Retrieval of the rescue boat by manual hoisting
Manual slewing by hand-pump.
