The invention discloses a
single point mooring system device, comprising floating hoses, one or two
mooring cables, a tumbler, buoys, a
mooring anchor chain, a mooring anchor
pile, flexible vertical pipes, an
umbilical cable and a manifold platform, wherein the floating hoses 1 are two parallel
pipe lines and float on the sea surface; the mooring anchor
pile is fixedly arranged on the
sea bottom; one end of the mooring anchor chain is tied on the buoys; the other end of the mooring anchor chain is tied on the mooring anchor
pile; the buoys are in a cylinder-shaped structure; the cylinder center is formed into an
open type center cabin; six sealed cabins are equally divided along the circumference; six sets of chain stoppers are evenly arranged on the outer sides of the bottom parts of the buoys; the tumbler is provided with four functional platforms, namely a mooring platform, a
piping platform, a balance platform and a center rotary table; the balance platform is arranged in a manner symmetric with the mooring platform and the
piping platform relative to the center platform; and moreover, the whole tumbler can rotate around the buoys. Through the
single point mooring system device, a complete set is formed with applicability of operations in various sea areas, and can provide oil tankers of 35 ten thousand tons within 100m
water depth with mooring for loading and unloading operations, so that a large berth
wharf is unnecessarily built.
