Rotary type mooring apparatus

Abstract

Abstract PURPOSE:To simplify the whole constitution of a rotary type mooring apparatus by laying a plurality of anchor chains radially onto a rotary plug installed rotatably onto a hull and arranging two winches for taking-out and driving-out the anchor chain. CONSTITUTION:A rotary plug 7 is installed rotatably onto a hull 8, and a plurality of anchor chains 3 are radially laid through the ship bottom part from the center opening on the rotary plug 7. Two winches 3 are arranged onto the hull 8 close to the rotary plug 7. Each anchor chain 3 radially laid and the winch 2 are freely connected and separated through a shackle and connection and separation from each anchor chain 3 are performed in succession by turning the hull 8 by a side thruster 9, and the necessary taking-out and driving-out are performed. Therefore, the installation of the winch for each anchor chain is not required, and the whole constitution can be made simple.
