Offshore Heavy Lift Rigging Analysis Using Spreadsheet
Publication: Practice Periodical on Structural Design and Construction
Volume 14, Issue 2
Abstract
A practical solution for offshore heavy lift rigging analysis using spreadsheet is presented in this paper. The procedure employed is based on the stiffness method with nonlinear geometrical considerations. The method is able to consider variations in the location of the center of gravity and slings make up in a quick and rational manner. The spreadsheet uses embedded visual basic macros to perform most of the computations. Parametric studies of heavy lifts can be performed easily using the spreadsheet to assess the sensitivity of the variables of the lift system. A simplified direct equation for skew load factor is proposed based on the results of the parametric studies.
