STRUCTURE OF COFFERDAM FOR 2-ROW TYPE TANK AND VESSEL HAVING THE SAME STRUCTURE

摘要

PURPOSE: A coffer-dam installation structure for a two-row tank and a ship and floating marine structure with the installation structure are provided to enhance the installation and heat transfer efficiency of a coffer dam by forming a common space coffer dam unit in a structure of connecting a transversal region and a longitudinal region using a common space coffer dam. CONSTITUTION: A coffer-dam installation structure for a two-row tank comprises a common space coffer dam(200). The common space coffer dam has a structure in which the inner spaces of a transversal region(210) and a longitudinal region(220) around the two-row tank are connected to each other by a structural member. One or more common space coffer dams are arranged on hull along the stem and stern. The transversal region is located on the stern of the hull and the longitudinal region is arranged to face the stem of the hull. The common space coffer dams are serially arranged on the stern of the hull along the stem.
