The present invention relates to an apparatus for passively preventing a marine floating body from twisting during mooring by controlling tension in ropes connected to the marine floating body within a predetermined allowable limit. The apparatus includes: a floating main body connected to the ropes, fixed on the sea, and providing a space for marine work; winches disposed on the floating main body and retracting or releasing the ropes fixing the floating main body; fairleads disposed on portions of the floating main body and guiding the ropes to the winches through themselves; and braking units disposed on portions of the floating main body at a predetermined distance from the fairleads, with the ropes passing through the fairleads and themselves, and controlling a speed of the ropes that are retracted to the winches at a predetermined speed.

The present disclosure relates to a natural gas hydrate tank container loading system for transporting natural gas hydrate, and the present disclosure provides a natural gas hydrate tank container loading system, enabling self-powered power generation and boil-off (BOG) gas treatment, includes: a refrigerator for inhibiting the generation of boil-off gas which naturally generates in a natural gas hydrate tank container during transportation; and a solar cell, a battery, and a generator, which operates by means of the boil-off gas, for supplying electric power to the refrigerator, thereby ensuring a generation capacity sufficient to operate the refrigerator by means of the solar cell, the generator, and the battery, and thus always maintaining a stable phase equilibrium (self-preservation) in the natural gas hydrate tank container even during long-distance transportation and solving problems of fire, environmental pollution, or the like which occur when the boil-off gas (BOG) is discharged to the outside.
