The present invention relates to an LPG tank and a cofferdam with a sandwich insulation structure applied, and a ship having the same. According to the present invention, the LPG tank has the sandwich insulation structure insulating the LPG stored inside from the outside. The sandwich insulation structure comprises: a second protection wall made of an inner side plate of the hull or a ship lower inner plate; a perimeter bar installed on an upper side of the second protection wall; a first protection wall installed on an upper side of the perimeter bar; a vacuum insulation panel built in a box space formed by the second protection wall, the perimeter bar, and the first protection wall; and polyurethane comprising a lower polyurethane formed between the vacuum insulation panel and the second protection wall, and an upper polyurethane formed between the vacuum insulation panel and the first protection wall. The perimeter bar forms the sandwich structure including: a lower plate connected to the second protection wall; an upper plate connected to the first protection wall; and an insulation layer formed between the lower plate and the upper plate. The present invention can reduce manufacturing costs.
