# §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.**
