置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a buoy moored in the sea that is not affected by waves, with a first feed hose connected to equipment installed on the seabed, and a second feed hose that is attached to a marine facility so as to be movable up and down and supported by a rigid body. The present invention relates to a submarine feed hose mooring device that prevents the feed hose from being damaged by waves by removably connecting each end of the feed hose to the feed hose.

Alternatively, when supplying driving fluid to equipment installed on the seabed, hoses for delivering these fluids are connected between the submarine oil well mouth, the submarine equipment, and the offshore facility. As you get closer to the sea surface, you are more susceptible to the effects of sea weather such as waves and wind, and as a result, the hose shakes around a lot and becomes fatigued, significantly shortening its useful life.In addition, when evacuating offshore facilities during stormy weather, the hose must be pulled up from the seabed. Therefore, it took a lot of effort and time to pull up the hose. Furthermore, since the connecting portion between the hose and the submarine equipment is installed on the seabed, maintenance and inspection of the connecting portion is difficult.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. A weight 1 is placed on the seabed B, and a wire lobe 2 is attached to the bottom of the water to avoid the effects of wind and waves. A hose joining device 4 is attached to the buoy 3 moored at a location, and the other end of the first fluid supply hose 5, which has one end attached to the joining device 4, is connected to an equipment 6 installed on the seabed, such as crude oil or natural gas from a submarine oil well. It is connected to equipment for collecting gas etc., equipment for collecting other submarine resources, etc., and one end is attached to the offshore facility 7 moored on the sea so that it can be raised and lowered freely, and the other end is detachably attached to the hose joining device 4. The second fluid supply hose 8 is supported by a rigid body 9 attached to the offshore facility 7 so as to be operable to raise and lower it.

。Therefore, to explain the case of pumping up a fluid such as crude oil or natural gas from an oil well mouth on the seabed, the fluid collected by the pumping equipment 6 installed on the seabed passes through the first supply hose 5 and the hose attached to the buoy 3. The oil flows into the second feed hose 8 by the joining device 4 and is fed to the oil storage tank of the marine facility 7.

The second supply hose sends the water from the pump of the offshore facility 7 through a route opposite to that described above, and is returned through the same route as described above.

である。As described above, the present invention moors a buoy at a depth of water that is not affected by wind, waves, etc., connects the buoy to the seabed with the first fluid supply hose, and moored the buoy at a depth of water that is not affected by wind, waves, etc. The first and second sections are connected by a second rigidly supported fluid delivery hose, and a hose connection device provided on the buoy connects the first and second fluid supply hoses. Since the second fluid delivery hose is in communication and the second fluid delivery hose is removably attached to the hose coupling device, the first fluid delivery hose is connected to the wind,
Since it is not affected by waves, etc., fatigue and damage caused by wind, waves, etc. are prevented and the useful life of the hose is improved, and there is no need to pull up the first fluid supply hose even in stormy weather. There is no need to remove the hose from equipment installed on the seabed, and since the second fluid supply hose is supported by a rigid body, there is no risk of bending fatigue or damage due to wind, waves, etc., and a reduction in service life is prevented. With,
In the event of rough weather, only the second fluid supply hose can be disconnected from the hose connection device and pulled up onto the offshore facility, which of course prevents bending fatigue and damage to the second fluid supply hose. There is no risk that the connection between the rigid body supporting the hose and the hose connection device will be damaged by rough waves, and since the connection is located at a much shallower depth than the seabed, the hose and the rigid body and hose It is easy to attach and detach the joining device, and its maintenance and inspection can be carried out without difficulty, and it is particularly effective as crude oil production equipment on the ocean floor in deep water.
