This invention relates to offshore structures.

With the rapid development of international industrialization and industry, the use of earth resources such as petroleum is gradually increasing, and thus the stable production and supply of oil is becoming a very important issue on a global scale.

For this reason, the development of marginal oil fields and deep-sea oil fields, which had been neglected due to economic difficulties, has become economical in recent years. Therefore, along with the development of submarine mining technology, drilling rigs with drilling facilities suitable for the development of these oilfields have been developed.

In other words, it is necessary to collect resources such as crude oil and gas buried in the seabed by limited resources. However, in order to be able to collect crude oil and gas in the deep sea area where the platform can not be installed, The plant was developed.

Drilling rigs and offshore plants are equipped with various drilling equipment to drill oil and gas existing under the sea floor, and a moonpool is formed in the center to allow the riser to move up and down.

Here, the riser is a device for recovering mud, sand, gravel and the like which are sprayed during drilling and protecting the drill pipe for drilling. In the drilling work, the riser is transported from the receiving part through the drill floor to the platform , And when the drilling operation is completed, it is again transported to the receiving place, which is the loading place, through the reverse route.

In particular, progressive exploration of deep-sea oil wells and exploration of polar-oil wells are progressing, and the development of rig ships as an offshore plant that can be applied to polar regions is continuously required. Along with this, depending on the cold outside conditions of the polar regions and the mooring situation of the limited supply boats, the importance of hose loading devices capable of receiving oil and bulk is increasing.

However, the hose loading device is exposed to the upper part of the deck due to the purpose of use such as fire generated from the upper part of the deck and accessibility to supply fluid to the outer boat, so that it is difficult to operate by cold air in the polar region.

The object of the present invention is to provide an offshore structure capable of preventing malfunction or malfunction of the hose loading device due to exposure to cold air in an environment such as a polar region.

Specifically, the closed space is composed of the interior of the deck, so that the inflow of ambient air into the hose loading device can be reduced.

Specifically, the hood loading device is provided at a lower portion of the deck, the deck has a hatch hole opposed to the outside air blocking portion, and the outside air blocking portion is formed at an upper portion of the deck, A hatch cover covering the hatch hole; And a box-shaped barrier provided on the hatch cover to define a space for the hose to pass therethrough.

Specifically, the hatch cover may be provided with a hose hanger to which the hose is fixed to be discharged in conjunction with the opening of the hatch hole.

In the offshore structure according to the present invention, the hose loading device is provided in the closed space inside the upper deck to prevent the hose loading device from being exposed to the outside of the offshore structure, so that the influence of the outside air is reduced, The operation of the hose loading apparatus can be smoothly performed, and the reliability of operation of the hose loading apparatus can be improved.
