DNV GL has issued Technical and Regulatory News including all related information you need when preparing a deck cargo for bulk carriers.
Structural strength
The deck and hatch covers on modern bulk carriers usually have a structural capacity of around 2.0 to 2.5 t/m2 of uniformly distributed load (UDL), without any reinforcements. This load corresponds to the green sea pressure used in the approval of the vessel. With a few minor reinforcements, it may be possible to increase the UDL, especially for the deck area.
Stability documentation
Compliance with applicable stability and longitudinal strength criteria in deck cargo loading conditions shall be shown in updated/amended stability manuals.
In general, intact GM limit curves shall be recalculated taking into account an additional wind profile area from deck cargo.
