%X The main equipment of offshore seismic exploration of China is the single channel seismic explore system. It is difficult to enhance the resolution in shallow strata. Pointing to the problem, the offshore high resolution multi-channel seismic streamer system is proposed. The system redounds to coastal research and ocean engineering. The quality of seismic profiles would enhance after onboard processings, such as velocity analysis, stacking and migration. The streamer has four sections. They are the deck segment, the leading vibration isolation segment, working segment, and tail segment. The hydrophones made by the Institute of Acoustics of Chinese Academy of Sciences are used. By means of calculation, the individual hydrophone element spacing in a group is determined as 0.15 m. The streamer group interval is determined as 3.125 m. Besides the structure discussion and an ocean engineering example are also presented in this paper.
