The opening / closing valves provided in the respective oil discharge holes may be operated independently according to the water detection signal of the water detection sensor of the oil discharge hole, or a separate control means may recognize the water detection signal of each water detection sensor, Can be selectively controlled.

In addition, a plurality of oil reservoirs are provided, and an oil discharge pipe connected to each oil reservoir is collected in an oil transfer pipe of the oil collecting member, and each oil discharge pipe can be selectively opened and blocked.

The marine structure having the oil collecting apparatus according to the present invention has the following effects.

When an oil spill occurs due to damage to the hull of an offshore structure, oil is collected on the oil collecting member provided on one side of the offshore structure, thereby preventing marine pollution. In addition, when seawater flows into the oil reservoir, the stability of the offshore structure can be maintained by sensing the incoming seawater.

The present invention proposes a technique for preventing leakage of oil to the oceans by collecting oil that is leaked out due to damage of an offshore structure by an oil collecting device. Specifically, when seawater is introduced into an oil reservoir located inside an offshore structure when an accident occurs due to damage to an offshore structure, the oil in the oil reservoir is located at the upper part of the seawater due to the difference in specific gravity with the seawater. When the seawater further flows into the oil reservoir, the oil located in the upper part of the seawater is transferred to and collected by the oil collecting member provided at one side of the offshore structure through the oil discharge pipe, It is possible to fundamentally prevent marine pollution caused by water.

Hereinafter, a marine structure having an oil collecting apparatus according to an embodiment of the present invention will be described in detail with reference to the drawings. In the present invention, an offshore structure refers to a drilling rig, an oil tanker, a ship, etc. having an oil reservoir.

2, an offshore structure having an oil collecting apparatus according to an embodiment of the present invention includes an oil reservoir 110, an oil discharge pipe 120, and an oil collecting member 130.

The oil reservoir 110 is provided in the interior of the marine structure, for example, inside the hull, and is composed of a closed space disconnected from the external environment. The oil discharge pipe 120 discharges the oil stored in the oil reservoir 110 when a pore is generated due to damage to the hull. In the oil reservoir 110, an oil discharge hole 111 is provided at regular intervals on a vertical line, and each oil discharge hole 111 is connected to the oil discharge pipe 120. 5 and 6), the oil in the oil reservoir is located at the upper part of the seawater due to the difference in specific gravity between the oil in the oil reservoir and the incoming seawater And is transferred to the oil discharge pipe 120 through the oil discharge hole 111.

The oil discharge pipe 120 extends to the oil collecting member 130 and the oil collecting member 130 collects the oil conveyed through the oil discharge pipe 120. The oil collecting member 130 needs to have a space of at least a certain volume in order to collect a predetermined amount of oil or more, and the oil collecting member 130 may be formed as a tube in one embodiment in consideration of normal space utilization . In other words, it can be constructed so as to have a space of a certain volume by injecting air immediately in case of an oil spill in case of being mounted on one side of an offshore structure in a state where air is normally removed, and it is made of fabric or reinforced vinyl, It has a strength and a small specific gravity so that it can float on the sea.

On the other hand, it is necessary to selectively transfer only the oil to the oil collecting member 130 in case of oil leakage. To this end, the following structure is added to the oil reservoir 110 and the oil discharge pipe 120.

As described above, the oil reservoir 110 is provided with oil discharge holes 111 spaced apart at regular intervals on a vertical line. The oil discharge holes 111 are formed in one side of the oil discharge holes 111, An on / off valve 112 for selectively opening and closing, and a water detection sensor 113 for detecting the presence or absence of water at the corresponding position. The water detection sensor 113 is a sensor for sensing water. When water is sensed by the water detection sensor 113, the oil discharge hole 111 at the corresponding position can be blocked by the opening / closing valve 112. The oil in the oil reservoir 110 is transferred to the oil discharge pipe 120 through the oil discharge hole 111 by discharging a certain amount or more of oil to increase the water level or to allow water to flow into the oil reservoir 110 The water sensor 113 provided in the oil discharge hole 111 of the corresponding position senses the water and the oil discharge hole 111 is selectively opened To prevent water from being transferred to the oil discharge pipe (120) through the oil discharge hole (111). The water detection sensor 113 and the on-off valve 112 provided in each oil discharge hole 111 are operated in conjunction with each other or the operation of all the water detection sensors 113 and the on- It can be controlled as a whole. That is, the opening and closing valves 112 provided in the respective oil discharge holes 111 are operated independently according to the water detection signal of the water detection sensor 113 of the corresponding oil discharge hole 111, It is possible to recognize the water detection signal of the water detection sensor 113 and selectively control the on / off valve 112 at a specific position. In addition, when the stability of the offshore structure occurs due to the horizontal or longitudinal inclination caused by the seawater flowing into the oil reservoir of the offshore structure by measuring the head of the seawater introduced by the water detection sensor, It is also possible to control the blocking or opening of the ball.

When a plurality of oil storages 110 are provided in the offshore structure, an oil discharge pipe 120 connected to each oil reservoir 110 is collected in an oil transportation pipe 131 provided on one side of the oil collecting member 130 In this case, a control valve 121 may be additionally provided at one side of each oil discharge pipe 120 to selectively open and shut off the oil discharge pipe 120 (see FIG. 4).

Meanwhile, the oil collecting member 130 is normally mounted on an offshore structure and is exposed to the oceans in case of an oil spill, but is preferably fixed by a fixing line 132 or the like to prevent the oil collecting member 130 from escaping (see FIGS. 3A and 3B) .
