APPARATUS FOR HEATING COFFERDAM AND FLOATING MARINE STRUCTURE HAVING THE APPARATUS

摘要

PURPOSE: A cofferdam heating apparatus, which is configured as a single integrated system where a pipe extended from a heater installed inside a lateral cofferdam is arranged inside a longitudinal cofferdam, and a floating marine structure having the same are provided. CONSTITUTION: A cofferdam heating apparatus for providing heat to the inside of a lateral cofferdam(20) and a longitudinal cofferdam(30) arranged between storage tanks(10) in a floating marine structure comprises a heat transfer unit, a pump, and a heat exchanger. The heat transfer unit is arranged inside the lateral cofferdam and the longitudinal cofferdam and transfers the heat provided from an external heat source to the inside of the lateral cofferdam and the longitudinal cofferdam. The pump circulates heat exchange media flowing through the heat transfer unit. The heat exchanger heats the heat exchange media which are cooled by passing through the inside of the longitudinal cofferdam and the lateral cofferdam.
