USCG Proposes Damage

Stability Rules

For Dry Cargo Ships

The U.S. Coast Guard recently proposed regulations which would require new dry cargo ships of 500 grt or more to meet a set minimum standard of subdivision and dam- age stability. The proposed rules would be in addition to an interna- tional standard which was devel- oped to ensure that a vessel could sustain damage without loss of the vessel.

The dividing of the internal por- tion of a ship into watertight com- partments is known as a subdivi- sion, and its purpose is to limit the amount of water which may be in- troduced into the ship as a result of hulldamageorpipingfailures. Dam- age stability is the ability of a ship to remain afloat and not capsize should any type of flooding occur.

The proposed regulations include roll-on/roll-off vessels and dry cargo vessels which are less than 328 feet long, and also feature a section which defines "subdivision length" and "new ship," as well as loading restriction requirements. Calcula- tions would be made for each ship to which the regulations apply in or- der to demonstrate compliance with the international requirements for damage stability of dry cargo ships.

For vessels less than 328 feet in length, a required index would be calculated from a given equation.
