Abstract

At present, theoretical calculation and model test about resistance and space state basically focus on a single underwater towed body, while the comprehensive resistance and stance of towed objects of multi-streamer seismic survey vessels are less concerned. For the convenience of the operators to predict the state of towed bodies in the sea quickly, the structure of multi-streamer seismic survey vessels for towed objects and the character of fluid resistance are analyzed on the basis of existing research on the fluid resistance of underwater towed objects. A simplified way to calculate the resistance and to estimate the horizontal stance is presented. This paper takes the configuration of common towed objects as an example, and the difference between estimation result and actual working status is within the permitted scope. The effectiveness of the proposed method is confirmed.
