Method of launching a large floatable object from a dock to water and delaunching it

摘要

A method of launching a large object such as a ship, barge or floatable offshore structure from a dock to water at a lower level than the dock surface by pushing the object over the dock edge, supporting the portion of the object extending past the dock edge on open bottom launch cans and continuing the procedure until the object is fully supported above the water only by the launch cans. By ballasting the launch cans the object is lowered into the water where it floats.
