The present invention relates to an LPG tank and a cofferdam applied with a sandwich insulation structure and a ship having the same. According to the present invention, the cofferdam is formed by a front transverse partition and a rear transverse partition, and divides a large number of tanks for storing LPG. The cofferdam is formed with a sandwich insulation structure in which at least one of the front transverse partition and the rear transverse partition forms a secondary protection wall. The sandwich insulation structure comprises: the secondary protection wall; a parameter bar installed on an upper side of the secondary protection wall; a primary protection wall installed on an upper side of the parameter bar; a vacuum insulation panel built in a box space formed by the secondary protection wall, the parameter bar, and the primary protection wall; and polyurethane including a lower polyurethane formed between the vacuum insulation panel and the secondary protection wall, and an upper polyurethane formed between the vacuum insulation panel and the primary protection wall. The present invention can reduce manufacturing costs.
