§155.240. Damage stability information for oil tankers and offshore oil barges.
33 C.F.R. § 155.240
Owners or operators of oil tankers and offshore oil barges shall ensure that their vessels have prearranged, prompt access to computerized, shore-based damage stability and residual structural strength calculation programs.
Vessel baseline strength and stability characteristics must be pre-entered into such programs and be consistent with the vessel's existing configuration.
Access to the shore-based calculation program must be available 24 hours a day.
At a minimum, the program must facilitate calculation of the following:
Residual hull girder strength based on the reported extent of damage.
Residual stability when the vessel's compartments are breached.
The most favorable off-loading, ballasting, or cargo transfer sequences to improve residual stability, reduce hull girder stresses, and reduce ground-force reaction.
The bending and shear stresses caused by pinnacle loads from grounding or stranding.
