Buoy including a mooring device

Claim 1

In a mooring device comprising a submerged buoy having a submerged portion of relatively large cross-sectional area and intersecting the surface of the water with a portion of relatively small cross-sectional area, a traction-resistant torsionally stiff connection between the buoy and a ground anchor, said connection having joints between the buoy and the anchor, an outrigger by which the buoy is connected above the water level to a buoyant body, means pivotally interconnecting the outrigger and the buoyant body for swinging movement about only a horizontal axis, the outrigger being connected to said portion of relatively small cross section of the buoy by a universal joint above the water level, and a conduit extending from the bottom toward the top of the buoy and by means of a swivel at said universal joint via the outrigger toward the buoyant body; the improvement comprising an auxiliary buoy, guiding arm interconnecting the auxiliary buoy with the first-mentioned buoy, a traction-resistant torsionally stiff connection between said auxiliary buoy and a ground anchor, joints between said last-mentioned connection and said auxiliary buoy and last-mentioned ground anchor, said conduit comprising pipe sections extending parallel to the last-mentioned torsionally stiff connection and having disconnectible flexible tube connections at the upper and lower ends of the last-mentioned connection, said conduit also comprising parts extending through said auxiliary buoy and a tube connection from the top of the auxiliary buoy to the top of the first-mentioned buoy.
