Designation
This system has been designed for installing onboard the sea-going vessels, of unrestricted navigation region, offering possibility of freefall launching of the lifeboat loaded with a complete set of passengers, even at a vessel's list up to 20o either way and/or trim up to 10o and remains operable at ambient temperature within the range from -30oC up to +65oC.
Moreover, the system will also allow for:
- launch of the boat with a complete set of passengers by means of a hydraulic davit arrangement;
- recovery of the boat with a crew of 3 to the stowage position by means of a hydraulic davit arrangement.
Rules and regulations
All components of the system comply with requirements of SOLAS 74 Convention - Consolidated Edition of 1992, IMO Resolution A.689/17 and requirements of particular classification societies as BV, DMA, DNV, GL, LR, MRS, MSA, PRS and SBG.
Specification
The complete Hydraulic Davit Freefall Survival System consists of a freefall lifeboat and launching arrangement comprising launching ramp, davit arm assembly, hydraulic winch and cylinders, hydraulic installation, traverse beam for boat suspension and necessary rigging. With slings disconnected and releasing pin unlocked the boat runs down the ramp and freefalls into the water. In case the freefall launching is unrealisable the design of the system enables also normal launching of the boat loaded with a complete set of passengers with a davit arm swung out by hydraulic cylinders and hydraulic winch that lowers the boat onto the water.The boat with a crew of 3 can be recovered and stowed in its normal position on the ramp the same way. Pump unit is provided with a hydraulic pump driven with
