Sec. 54.05-30  Allowable stress values at low temperatures.

    (a) The Coast Guard will give consideration to the enhanced yield

low temperature for the purpose of establishing allowable stress values 
for service temperature below 0 [deg]F.
    (b) The use of such allowable stress values must be specially 
approved by the Coast Guard for each application. Further information 
may be obtained by writing to the Coast Guard (G-MSE).
    (c) Submittals must include information and calculations specified 
by the Coast Guard (G-MSE) to demonstrate that the allowable stress for 
the material cannot be exceeded under any possible combination of vessel 
loads and metal temperature.
