Slipway Hoist System for Marine Vessel Slippage
What work was done by Qualter Hall on this Marine Vessel Slippage System?
The system comprises cradles which are pulled up the slipway by a hoisting system designed by our team and manufactured in the Qualter Hall workshop. It is operated using a control system designed and installed by our specialist in-house controls and commissioning teams.
This project was planned in two phases. Initially, our team designed, supplied, installed and commissioned the central slipway carriage and winching system. Subsequently for phase two, we replaced the two remaining outer carriages with similar upgraded units, each one specifically designed to maximise the space available on the slipway
During phase one a new central carriage and winching system replaced existing units which were beyond economical repair, with the winching system being required to operate a further two existing outer carriages.
The carriage itself incorporates an innovative feature for Kilkeel, having hydraulically actuated support beams. This removes the need for building keel blocks to suit every slipped vessel, dramatically increasing efficiency on the slipway.
The travelling winch system comprises two individual hoisting units which are synchronised to load share and speed match, providing 100% redundancy in the event of rope or hoist failure.
Control of the system is available at the winch house and the carriage mounted kiosk, or by radio pack allowing operation from onboard the incoming/outgoing vessel.
