GB/T 41888-2022 in English

Core Essentials of Technical Standards

This standard innovatively integrates the marine airbag power calculation model and the graded construction requirements of the slideway, and defines differentiated construction specifications for four types of ships. For the first time, the moment balance formula verification requirements are clearly proposed for Class III/IV large-tonnage ships. The number of airbags in the quick calculation method is arranged. The contact length at the mid-section of the ship is directly related to the square coefficient...

Compared with the first generation of technology in 2005, the 2022 version includes three major technological breakthroughs: stepped micro-pressure control replaces the original instantaneous full pressure mode, and the measured loss rate is reduced by 58%; the dynamic push-up model is used to replace the static bag arrangement scheme, and the risk of lateral capsizing is reduced by 76%; the new laser three-dimensional slope calibration system makes the relative error of the entry angle controlled within ±0.3°...
