A mooring apparatus using a submerged pontoon that does not interfere with floaters and sailing vessels, is not affected by oceanic weather conditions by being submerged at a constant depth, easily separates the floater such as FPSO from the submerged pontoon, in order to cope with an emergency such as stormy weather and avoids collision, and, upon the emergency being terminated, enables the floater such as FPSO to return to the operation area and moor to the submerged pontoon and start the operation. An apparatus for mooring a floater using a submerged pontoon including a submerged pontoon that is placed and fixed at a constant depth below the bottom of the floater, wherein the submerged pontoon is fabricated with buoyant pipes, assumes a planar polygon, is lashed by ropes that are connected to weights or anchors on the seabed and is lashed by ropes that are connected to the floater.

The apparatus for mooring a floater using a submerged pontoon of claim 1, wherein the submerged pontoon configured into a closed one-piece pipe or with two or more pipes, which are occluded at both ends, intersecting with each other to form one or more of linear, crossed and tri-pronged structures, extend to the positions of adjacent floaters. 3. The apparatus for mooring a floater using a submerged pontoon of claim 1, wherein the internal cross-section of the pipes that constitute the submerged pontoon is any one of an occluded shape that assumes any one shape of a circle, an ellipse or a polygonal, open shape that is open at an end or fin shaped that has, internally or externally, along the length of the pipe, a fin structure in one or more longitudinal, horizontal or diagonal directions. 4. The apparatus for mooring a floater using a submerged pontoon of claim 1, wherein the ropes includes two or more pontoon mooring ropes, one end of each pontoon mooring rope is connected to each of one or more weights on the seabed while the other end of each pontoon mooring rope is connected to the submerged pontoon; two or more anchor ropes, one end of each anchor rope is connected to each of one or more anchors on the seabed while the other end of each anchor rope is connected to the submerged pontoon; and two or more floater mooring ropes, one end of each floater mooring rope is connected to the floater while the other end of each floater mooring rope is connected to the submerged pontoon. 5. The apparatus for mooring a floater using a submerged pontoon of claim 4, wherein the submerged pontoon includes one or more stays that connect vertexes or corners that face each other or sit oppose to each other or points between the two corners to make diagonals or quasi-diagonals. 6. The apparatus for mooring a floater using a submerged pontoon of claim 4, wherein the floater mooring ropes includes a buoy that is to be connected by an extension lead after an end of the floater mooring rope is disconnected from the floater. 7. The apparatus for mooring a floater using a submerged pontoon of claim 6, wherein the buoy is equipped with a self-descending buoyancy controller that automatically submerges and emerges by generating and eliminating, respectively, buoyancy according to ultrasonic signals. 8. The apparatus for mooring a floater using a submerged pontoon of claim 1, wherein the floater is equipped with a length controller that winds or releases the rope to control the rope length by measuring the change in the draft of the floater and the tension of the rope according to buoyancy change. 9. The apparatus for mooring a floater using a submerged pontoon of claim 1, wherein the submerged pontoon includes a buoyancy regulator that increases or decreases the buoyancy by means any one of a piston system that make water be charged to or discharged from compartments and a compressed air supplier that injects water into compartments by opening a valve or pushes against water by injecting compressed air into the compartments.
