    Hello and warm wishes for the new year from TheNavalArch!

    We are glad to publish a new article titled Preliminary Rigging Arrangement Design OF 4 point, Single Hook Lifts for Non-Specialists by Michael Harwood

    This article is intended to provide guidance to non-specialists (including knowledgeable designers) in developing slightly conservative preliminary lift rigging designs. Two cases are considered - with and without a spreader bar.

    An excerpt is presented below:

    "
    Preliminary rigging design as described here is summarized in the table below and further described in notes following the table.

    • Obtain/Calculate a best estimate of the Package weight along with its expected centre-of-gravity (CoG).
    • Establish the Package lift points
    • Work out the key setting-out work points of the selected rigging system
    • Estimate the sling forces in the rigging system
    • Form a table of work points developed in Step #3 to be exported for use in constructing a “starter model” with AutoCAD 3D
    • Build the input for Rigging System sub-model to be exported for use by a Structural analysis program
