Abstract: A floating offshore structure to which a one-side spread mooring system is applied is provided. The floating offshore structure includes: first mooring lines fastened to one of a port and a starboard of a hull, the first mooring lines being spread out in a first direction, which is a direction away from the hull, into a seabed; and second mooring lines fastened to the same side of the hull as the first mooring lines, the second mooring lines being spread out in a second direction, which is a direction toward an opposite side of a centerline of the hull to the first mooring lines, into the seabed through a lower space of the hull.

Abstract: Disclosed is a floating marine apparatus including a liquefied natural gas (LNG) tank.

Abstract: Mobile telecommunication service system and method using a public frequency are provided. The method includes receiving a call connection request for a certain recipient from a mobile communication terminal; and connecting a radio interval between the mobile communication terminal and a Base station Transceiver Subsystem (BTS) of a call connection interval of the mobile communication terminal and the certain recipient, using a public frequency band. Accordingly, it is possible to stably connect the call to the public institution in case of the emergency or the public operation. By raising the utilization of the limited frequency resources, the insufficient frequency in the private mobile telecommunication can be addressed. The public institutions provide the public frequency to the private telecommunication companies and use the mobile communication service for free or at a low cost in return.
