According to an aspect of the present invention, an oil unloading hose used when unloading oil from a first vessel equipped with a flare tower to a second vessel, the hose body floating on the sea; And a heat dissipation layer formed on an outer circumferential surface of the hose body, there is provided a floating oil unloading hose.

Description

Floating type hose for unloading oil}

The present invention relates to a hose for unloading oil.

Hoses are used to unload oil stored in ships such as crude oil carriers, FPSOs, and drilling vessels. Floating hoses are used as one of these hoses. Such floating hoses are made of, for example, a material less dense than water in the hose, and float on the sea in the process of unloading oil.

However, a problem arises when such a floating hose is used to unload oil from a ship equipped with a flare tower. Heat or sparks from the flames in the flare tower can damage hoses floating at sea.

An embodiment of the present invention is to provide an oil unloading hose configured to prevent damage by flame generated in a flare tower.

According to an aspect of the present invention, an oil unloading hose used when unloading oil from a first vessel equipped with a flare tower to a second vessel, the hose body floating on the sea; And a heat dissipation layer formed on an outer circumferential surface of the hose body, there is provided a floating oil unloading hose.

In this case, the hose body is made of a double tube structure including an inner tube and the outer appearance, the inner tube and the outer tube may be filled with a material having a lower density than water.

At this time, the heat dissipation layer may be formed in the damage possible region by the flame generated in the flare tower.

According to the embodiment of the present invention, the heat dissipation layer is formed on the outer circumferential surface of the floating hose body, it is possible to effectively prevent the hose from being damaged by the flame generated in the flare tower.

BRIEF DESCRIPTION OF THE DRAWINGS The present invention is capable of various modifications and various embodiments, and specific embodiments are illustrated in the drawings and described in detail in the detailed description. It is to be understood, however, that the invention is not to be limited to the specific embodiments, but includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Referring to the accompanying drawings, the same or corresponding components are denoted by the same reference numerals, do.

1 is a view schematically illustrating an oil unloading hose according to an embodiment of the present invention, and FIG. 2 is an enlarged view of portion A of FIG. 1. 1 and 2, the oil unloading hose 10 according to the present embodiment includes a hose body 20 and a heat dissipation layer 30, and the first vessel 1 to the second vessel 2. Used to unload oil.

Here, the first vessel 1 may be a vessel for processing oil, for example, a vessel for drilling or producing crude oil. Such a first vessel 1 may include conventional drillships, semi submersibles, FPSOs, FPOs, and the like. In this case, the oil drilled or produced by the first vessel 1 can be offloaded by the mooring line 4 to the second vessel 2 mooring behind the first vessel 1.

Alternatively, the first vessel 1 may be a vessel used for recovering oil in an accident well (not shown) in which oil may leak or leak due to an accident. The first vessel 1 is equipped with a recovery facility (not shown) for recovering the oil of the accident well, the recovery facility may include a drilling pipe (not shown) for drilling the accident well. In this case, the oil recovered from the accident well by the first vessel 1 may be transferred to and stored in the second vessel 2 moored behind the first vessel 1.

The hose body 20 provides a moving passage of oil which is unloaded from the first vessel 1 to the second vessel 2.

The hose body 20 is configured to float on the sea. To this end, the hose body 20 may be of a double tube structure including, for example, an inner tube 21 and an outer tube 22, and the inner tube 21 and the outer tube 22 may be filled with a material having a lower density than water. Can be.

In addition, various types of hose bodies 20 floating on the sea may be proposed.

The heat dissipation layer 30 is formed on the outer circumferential surface of the hose body 20. The heat dissipation layer 30 may be formed by applying a heat dissipation material such as heat dissipation paint to the outer circumferential surface of the hose body 20. Alternatively, the heat dissipation layer 30 may be formed on the outer circumferential surface of the hose body 20 by attaching, for example, a heat dissipation tape separately manufactured from the hose body 20.

Such a heat dissipation layer 30 can effectively prevent the hose 10 from being damaged by heat or fire caused by the flame generated from the flare tower (3).

According to the present embodiment, the heat dissipation layer 30 may be located in the damageable area D (see FIG. 1). Here, the damageable area D is an area in which flare tower 3 (see FIG. 1) for incineration of crude oil or gas is expected to be damaged by heat or sparks caused by a flame generated during incineration of crude oil or gas. The amount of crude oil or gas incinerated in the flare tower 3 (see FIG. 1), the height of the flare tower 3 (see FIG. 1), the wind strength, the wind direction, and the like can be determined experimentally.

In this case, the heat dissipation layer 30 may be formed only in the damageable region D without forming the heat dissipation layer 30 over the entire length of the hose 10, thereby reducing the material cost and simplifying the manufacturing process.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, many modifications and changes may be made by those skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims. The present invention can be variously modified and changed by those skilled in the art, and it is also within the scope of the present invention.
