1. (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.
2. (b) Vessel baseline strength and stability characteristics must be pre-entered into such programs and be consistent with the vessel's existing configuration.
3. (c) Access to the shore-based calculation program must be available 24 hours a day.

4. (d) At a minimum, the program must facilitate calculation of the following:

   1. (1) Residual hull girder strength based on the reported extent of damage.
   2. (2) Residual stability when the vessel's compartments are breached.
   3. (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. (4) The bending and shear stresses caused by pinnacle loads from grounding or stranding.
