Analysis and Calculation of Ocean Current Load and Wave Load on a Floating Crane under a Normal Working State

Zhu, F.; Jiang, Y., and Li, W., 2015. Analysis and calculation of ocean current load and wave load on a floating crane under a normal working state.

This paper takes a certain ultra-large all-slewing floating crane as the research object, analyzing its ocean current load, wave load and their effects on the vessel in the process of normal work. The paper discusses the ocean current and wave load impact on the stability of the floating crane, and how the horizontal impact force and crosswise moments of force are calculated according to the given parameters when the floating crane is affected by crosswise and lengthwise ocean currents. Furthermore, the perpendicular disturbance moments and crosswise drifting forces are calculated based on horizontal and vertical waves. Finally, this approach makes a basis for anti-overturn stability calculations.
