Abstract:
PURPOSE: A pressure tank module for a carbon dioxide carrier ship and a control method thereof are provided to reduce unnecessary manufacturing costs and the amount of used raw materials caused by designing the thickness of a pressure tank thicker than needs. CONSTITUTION: A pressure tank module for a carbon dioxide carrier ship comprises a pressure tank(100), a safety valve(200), an exhaust valve(300), and a control part(400). The pressure tank is manufactured at a design pressure higher than a shipping pressure of when liquid carbon dioxide is shipped. The pressure tank is mounted on a ship and maintains a sealed state. The safety valve is installed in one side of the pressure tank. When the internal pressure of the pressure tank is drastically and abnormally risen to the design pressure, the safety valve is opened to discharge the boil-off gas of the liquid carbon dioxide received in the pressure tank so that the internal pressure of the pressure tank can be dropped. The exhaust valve is mounted in one side of the pressure tank. When the internal pressure of the pressure tank is risen, the exhaust valve is opened to discharge the boil-off gas of the liquid carbon dioxide received in the pressure tank so that the internal pressure of the pressure tank can be maintained within a constant range. The control part detects the internal pressure of the pressure tank and checks whether or not the internal pressure of the pressure tank is reached at a predetermined set pressure and the design pressure to operate the opening and closing of the exhaust valve.

PURPOSE: A power management system and method for a new and regeneration energy generation plant are provided to store surplus power produced in a new and regeneration energy generation part by including a power storage part. CONSTITUTION: A new and regeneration energy generation part(10) produces power by using new and regeneration energy. A first power control part(20) controls the transmission of power produced from the new and regeneration energy generation part. A power use plant part(30) produces fuel energy by using the power from the new and regeneration energy generation part. A power storage part(40) stores residual power from the new and regeneration energy generation part. A second power control part(50) controls the transmission of the power stored in the power storage part.

PURPOSE: An upper support structure of a floating marine structure and a method thereof are provided to disperse the load of a deck and equipment through properly installed non-tight girders. CONSTITUTION: A floating marine structure(1) comprises equipment(35) which are installed on an upper wall(14) of a hull(10) and liquefy natural gas, a plurality of stools(30) which are arranged between the equipment and the upper wall in order to support the equipment, inner walls(18) which are installed lengthwise inside the hull in order to divide storage tanks(20) installed under the upper wall into two rows, and a trunk part(19) which is formed between the inner walls and the upper wall.
Abstract:
PURPOSE: A movable port is provided to promote the more effective marine transportation and operation of harbor facilities by loading and unloading cargos in a sea area away from harbor facilities located on land, to exclude the work for controlling the quantity of water in a ballast tank by keeping the submerged depth in the seawater regularly regardless of the amount of cargos loaded and securing the required draft, and to prevent the disturbance and contamination of a marine ecosystem. CONSTITUTION: A movable port comprises a main platform(10) having transportation equipment(12) for loading and unloading cargos(3) and a mooring portion(14) for mooring an external vessel(1), and a sub platform(20) mooring to the main platform and having a non-watertight space for allowing seawater to enter and leave, wherein a basket type loading box(7) is installed to the non-watertight space to be separable to load the cargos within.

Abstract:
PURPOSE: A tension adjusting device and a tension control system of the tendon at a TLP(tesnioned leg platform) are provided to control tension in real time by the selection of remote controllable equipment and to reduce manufacturing/working cost by the minimizing of the number of installation positions of an existing ballast system and a pump system. CONSTITUTION: A tension adjusting device of the tendon at a TLP(tesnioned leg platform) comprises a motor(M) and a tendon tension adjusting unit(240). The motor generates forward or backward rotating movement depending on a signal. The tendon tension adjusting unit is installed on the end of the tendon. The tendon tension adjusting unit converts forward and backward rotation by the motor to translating movement to vary the tension of the tendon. The tendon tension adjusting unit controls the length of the tendon by raising or lowering the tendon by the translating movement using a screw jack. The tendon tension adjusting unit controls the length of the tendon by raising or lowering the tendon by the translating movement using a turn buckle.
