Sec. 155.240  Damage stability information for oil tankers and offshore 
oil barges.

    (a) 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.
    (b) Vessel baseline strength and stability characteristics must be 
pre-entered into such programs and be consistent with the vessel's 
existing configuration.
    (c) Access to the shore-based calculation program must be available 
24 hours a day.
    (d) At a minimum, the program must facilitate calculation of the 
following:
    (1) Residual hull girder strength based on the reported extent of 
damage.
    (2) Residual stability when the vessel's compartments are breached.
    (3) The most favorable off-loading, ballasting, or cargo transfer 
sequences to improve residual stability, reduce hull girder stresses, 
and reduce ground-force reaction.
    (4) The bending and shear stresses caused by pinnacle loads from 
grounding or stranding.
