COFFER DAM HEATER AND A FLOATING MARINE STRUCTURE WITH THE SAME, CAPABLE OF BEING USED AS THE REFRIGERANT FOR COOLING A VARIETY OF EQUIPMENT IN THE FLOATING MARINE STRUCTURE

摘要

PURPOSE: A coffer dam heater and a floating marine structure with the same are provided so that a heat exchange medium, which transfers the heat into the coffer dam and cools itself, is used as the refrigerant for cooling a variety of equipment.;CONSTITUTION: A coffer dam heater comprises a pipe(31), a pump(32) and a cold heat retrieving device. The pipe is arranged over the inside and the outside of a longitudinal coffer dam, which is extended along the hull length of the floating marine structure. It is arranged through inside and outside of the longitudinal direction coffer dam. The pump transfers the heat exchange medium in the pipe. The cold heat retrieving device retrieves the cold heat from the heat exchange medium cooled in the process of passing through the inside of the longitudinal coffer dam. The cold heat retrieving device is installed on the floating marine structure and needs to be cooled in operation.;COPYRIGHT KIPO 2011
