Life rafts, which has been used for domestic vessel currently, are fabricated mostly for the ocean-going vessels in accordance with the SOLAS Resolution. Therefore, there is not any small-sized life raft which can be installed on small fishery boat, leisure boat and cargo vessel with those length shorter than 20 meters in our country. However, in many foreign countries, new standards or the small-sized life rafts applicable to those small vessel have been developed according to the standard of ISO 9650. Furthermore, they make their effort to contribute the safety for the life at sea by supply the superior product of life rafts, which have been adopted by light material (i.e. thermoplastic polyurethane, TPU) and economic production process (i.e. heat sealing, radio-frequency welding, RFW), etc. In this paper, the development results of the small-sized life raft, which has been used the lightening material TPU and fabricated by RF-welding method, will be introduced.
