4.1 Load calculation point
4.1.1 The load calculation point is located at the middle of the full
length, ℓ, at the attachment point of the primary supporting member with its attached
plate. However, for primary supporting members in the cargo hold region the requirements
in Pt 2, Ch 1, Sec 4, [4], as applicable, for bulk carriers and Pt 2, Ch 2, Sec 3, [1]
for oil tankers are to be followed.
For primary supporting members located on transom plate, the y coordinate of the load
calculation point is to be taken corresponding to y value at side shell at z level of
load calculation point for the external dynamic pressure calculation.
