DAF - Offshore Lift Spreader Bar 1

[hungrydinosaur]

Hi All,

As per DNV Rules for Lifting Appliance, what is the DAF we need to use for a spreader bar of SWL 400 Tonnes? Also, any idea on what GL mentions for this? Thanks in advance.

Also a table is applicable for offshore lift in air in minor sea states, typically Hs <2-2.5m, see
DNV Rules for Marine Operations, 1996, Pt.2 Ch.5 Lifting –Capacity Checks
Table 2.1 Pt.2 Ch.5 Sec.2.2.4.4
