INSTRUCTION FOR USE OF SPREADSHEETGeneral InformationThis spreadsheet calculates the rigging required for a 4-point lift according to DNV standard, Rules forPlanning and Execution of Marine Operations, Part 2, Chapter 5 for lifts >50T.

Refer to ASSUMPTIONS on Design Report page in addition to this information.Note that symmetry is not required and padeyes can be place at any x,y and z coordinates.

Limitations1) 4 leg lift only2) IWRC GR1770 wire rope and Green Pin shackles and masterlinks only

3) Wire rope diameter is only calculated for the critical sling and UC is based on this sling

4) Above water/ offshore/ onshore/ on-platform/ inshore lifts only

5) Single hook lift only

Coordinate System yCOG is at the origin 2

z axis is verticalx and y axis are in the horizontal planeLifting points are labelled anti-clockwise starting from the positive x and y quadrant 3

Inputs requiredAll inputs are in blueThe title block needs to be completed on the first page of the design report onlyInputs

1 Type of lift- Select as applicable (Offshore, On-platform, Inshore, Onshore)

2 Lift weight, to nearest 0.1T

3 Rigging weight, zero initally

4 D/d ratio must be greater than or equal to 4 (DNV Pt2, Ch5, Section 3.1.3), if no bending enter 4

5 Minimum sling angle (must be >= 60 deg)

6 Configuration and tolerance

7 Lifting point coordinates defined with COG at origin

8 Skew factor data, only required for 4 point, approximately double symmetric lifts

9 Sling details are used to determine sling safety factors

10 Override rigging selection

The spreadsheet will determine the rigging with UC's closest to 1

If a lower UC is desired input larger rigging size 11 Splicing reduction factor. Equivalent to termination factor in WEL standard.12 Padeye UC from padeye spreadsheet

SOLVINGDefine all required inputs as above. Solve without rigging weight and then increase weight by including rigging weight to determine UC's. If original UC's are close to 1 the rigging required may change and the process repeated. If the approx UC is used for the SKL calculation this should be checked against the results and iterated if required.

Other Relevant InformationInput 1 Type of lift: Inshore, Onshore/ On-platform or Offshore

This spreadsheet calculates the rigging required for a 4-point lift according to DNV standard, Rules for Input 4 If no bending insert a number greater than 4Input 6 The rigging configuration and tolerance effects the SKL.

Three rigging configurations and SKL calculation methods as below: i) Symmetrical and within specified tolerance, SKL=1.25, section 2.3.2.5ii) Approximately symmetrical, outside tolerance, SKL calculated as per section 2.3.2.7iii) Any unusual geometry, SKL calculated assuming one leg inactive at a time

Input 8 The SKL is dependent on the sling load, and diameter so cannot be directly calculated.A best estimate of fabrication tolerance and UC is required. The lower the UC the higher the SKL, therefore the design should not be too conservative.

Wire rope diameter is only calculated for the critical sling and UC is based on this sling Input 9
