A Deep Diving System (DDS) has recently been completed after the successful shop test at Kobe Shipyard of Kawasaki Heavy Industries, Ltd. This system is planned to be mounted on a submarine tender (AS) for delivery to the Japan Defence Agency. The DDS consists of 1PTC (Personnel Transfer Capsule), 2DDC_s (Deck Decompression Chamber), 2MCC_s (Main Control Console) and supporting system. This system is designed to enable saturation diving up to 300m depth by total 12divers. The saturation diving is accomplished by the long term residence of divers under the high pressure of helium mixed gas corresponding to the diving depth. So, the environmental control inside the chambers are very important to keep the life and safety of the divers. Based on the knowledge on diving medicine and hyperbaric (high pressure) physiology, environment control system is designed and equipped. In the design of environmental control system, the special discussions are held about the environmental control criteria, adoption of external circulating system and temperature control responce. The various shop tests were carried out including unmanned operational test under 300m diving pressure and manned operational test under 60m diving pressure. Through the shop tests, fine environmental control performances are attained, as follows: pressure control accuracy: ±0.3m depth oxygen partial pressure control accuracy:±0.02 kgf/cm^2 temperature control accuracy:±0.5℃
