Its main advantages in comparison with other methods normally used up to now are: less expensive, time saving, no need for specially designated water area, direct visual observation, good reliability and safety. The working principle has been presented with the example of two platforms 'Bohai No. 8' and 'Bohai No. 10', to which the method was used. Also a comprehensive comparison with other methods in technological and economical aspects is given in the paper.展开更多
