本発明は、洋上でヘリコプターが燃料を補給するため等
に使用する一本コラム自立式の洋上ヘリポートに関する
ものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a single-column self-supporting offshore helipad used for refueling helicopters on the ocean.
洋上でヘリコプターに燃料を補給するためには、ヘリコ
プター支援船か、人工島、またはやぐらを必要とするが
、人工島、またはやぐらは水深が深くなれば、その設置
コストが高価になる。Refueling helicopters at sea requires a helicopter support vessel or an artificial island or tower, but the deeper the water, the more expensive it becomes to install an artificial island or tower.
また、オフショア．リグのごとく、目的地が固定されて
いる時には、移動する船をヘリポートとして使用する必
要はない。一方、ブイやガイドタワーをヘリポートとし
て使用すると、荒天時にへりデッキに煩斜が生じて、安
全な着陸ができない。Also offshore. When the destination is fixed, like a rig, there is no need to use a moving ship as a helipad. On the other hand, if a buoy or guide tower is used as a helipad, the edge deck will become sloped during stormy weather, making it impossible to land safely.
そこで本発明は、ヘリポートとして使用される本体が荒

より構成される。That is, in the offshore helipad of the present invention, the lower end of the column, which is provided so as to be able to stand upright in water by adjusting its buoyancy, is connected to the anchor via the pole joint and its housing, and the upper end of the column is connected to the anchor through the ball joint and its housing. It is connected to the IJ deck through the housing, and then vertically connected by wire to each eye plate provided correspondingly on the IJ deck and anchor on the same radius from the center of the upper and lower ball joints. be done.

うにしている。Next, top. A cylindrical structure 6, which is a column whose lower end is rotatably connected by a ball joint 5.5', is established perpendicularly to the ball joint housing 3, and its upper end is positioned sufficiently higher than the water surface W, and the ball joint 5 is connected to the edge deck 7. The ball joint housing 8 is connected to the ball joint housing 8 provided in the center of the ball joint housing 8, and a ball joint cover plate 9 prevents the ball joint from falling off.

１３′をそれぞれ適当に設けている。On the other hand, eye plates 11, 11' are arranged on the foundation material of the truss 7' constituting the helideck 7, corresponding to each other on the circumference having the same diameter as the eye plates 10, 10' on the upper surface of the anchor 2. Eyeplate 10 and 11 and 1.0
' and 11', in this embodiment eight wires 12,
12' are vertically connected to each other by wires 12'.
, 12', the rigging screws 13,
13' are provided appropriately.
ここで、コラムである円筒形構造物６には、必要な浮力

しようとする。Here, the cylindrical structure 6 that is the column is given the necessary buoyancy to stand upright in still water, but this buoyancy always maintains a positive buoyancy even when the tide level changes or wave troughs occur. If you adjust it so that it will stand upright, it will try to stand upright under any sea conditions.

る。On the other hand, even if the cylindrical structure 6 is tilted due to tides, wind, or wave forces, the edge deck 7 always moves while forming a plane parallel to the plane of the anchor 2 due to the wires 12 and 12'.
If the plane of the anchor 2 is installed horizontally, the helideck 7 is always held horizontally. Therefore, in the offshore helipad of the present invention, the lower end of the column having pole joints at both ends is connected to the anchor, the upper end is connected to the edge deck, and the eye plate on the circumference of the helideck and the eye plate on the anchor with the same diameter are connected in parallel to each other. Since the anchor plane and the helj deck plane are always held horizontally independently of the mirror of the column by tying them together with ropes of length or length, even if the main body of the anchor is distorted, the heli deck on the upper deck The plane remains level, allowing the helicopter to land safely.
また、本発明の洋上ヘリポートは構造も簡単であり、か
つ、その製作コストも比較的安価である。Furthermore, the offshore helipad of the present invention has a simple structure and is relatively inexpensive to manufacture.
