Description

Crane for floating offshore structure and floating offshore structure including the same The present invention relates to a crane for a floating offshore structure and a floating offshore structure including the same, and more specifically, to a crane for a floating offshore structure and a floating offshore structure including the same capable of protecting a pilot boarding a cabin provided for operating the crane from heat and radiation. Generally, floating offshore structures include FPSO (Floating, Production, Storage and Offloading), LNG-FPSO, FSO (Floating Storage Offloading Unit), and FSRU (Floating Storage and Regasification Unit). These floating offshore structures perform exploration and extraction operations for the production of various resources from the deep sea. Crude oil or natural gas produced through these drilling operations are transported from the underwater production facilities to the aforementioned floating offshore structures via equipment such as risers. The transported crude oil or natural gas undergoes a separation process through refining and can then be transferred to land via separate transport vessels. During this refining process, toxic or low-productivity waste gases or waste oil are incinerated using a flare tower. The flare tower is designed to be tall to prevent heat radiation from the incineration from affecting the production facilities and workers. Meanwhile, cranes are used on floating offshore structures to load and unload cargo. Cranes are equipped with a boom that varies in length and inclination angle, and a cockpit is provided to control this boom. The cockpit is located at a certain height above the ground, and an operator sits in the cockpit to control the boom. Since the operator must monitor changes in the boom's length and inclination angle from the cockpit, they are positioned as close as possible to the height of the boom. Due to the crane's structure, safety issues may arise as large amounts of heat and radiation emitted during the incineration process of the flare tower in emergency situations may come into contact with the crane operator.

FIG. 2 is a drawing showing the structure of a protection unit for a crane for a floating offshore structure according to one embodiment of the present invention. FIG. 3 is a drawing showing the pre-operation state of a crane protection unit for a floating offshore structure according to one embodiment of the present invention. FIG. 4 is a drawing showing the state after operation of a crane protection unit for a floating offshore structure according to one embodiment of the present invention. FIG. 5 is a drawing showing the structure of one side of the cabin after operation of a crane protection unit for a floating offshore structure according to one embodiment of the present invention. Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following embodiments are presented to sufficiently convey the concept of the present invention to those skilled in the art to which the present invention pertains. The present invention is not limited to the embodiments presented herein and may be embodied in other forms. In order to clarify the present invention, the drawings may omit the illustration of parts unrelated to the description and may slightly exaggerate the size of components to aid understanding. FIG. 1 is a drawing showing a floating offshore structure according to one embodiment of the present invention. Referring to FIG. 1, a floating offshore structure (10) according to one embodiment of the present invention may largely include a flare tower (100) and a crane (200) for a floating offshore structure.
