Special work ship (such as Marine survey ship, rescue ship, etc.) in the deck stern operation, need to release detection instrument (such as AUV) to work in the sea or recover from the sea water to complete the work of the instrument, generally through A ship installed in the deck stern can swing back and forth A frame device to achieve.

 

Rack device of such A frame back and forth, filed instruments can easily from the deck, can also smooth recovery instruments from sea level, in order to achieve the instrument from the deck to the release of the surface process, the instrument is boosted by A derrick left deck, need through A derrick ontology across stern deck bulwark (or rail) to achieve safe release distance can be released to the water, This requirement is such that the height of the A-frame should not fall below A certain limit value. In the design of a salvage vessel, this limit is up to 10.8 m. This kind of high A frame has A more adverse effect on the ship's center of gravity. Second, the arrangement of stern deck needs to occupy a larger space; The third is to produce a large side wind area, the ship stability has an adverse impact.

 

Therefore, A kind of A-frame device which can not only meet the requirements of the height limit, but also eliminate the adverse effect on the ship as far as possible is needed to ensure the smooth realization of the engineering operation.
