Pressure Rise in a Vented Cargo Tank due to External Heating.

Abstract

The normal venting capacity of marine cargo tanks appears to be adequate for relieving vapor generated when integral tanks are exposed to an external fire. However, the unwetted tank walls surrounding the ullage are subject to substantial weakening in those cases where the fire heat flux increases the wall temperature above 1000 deg. F. Convection and radiation can adequately cool the unwetted wall only for incident heat flux less than 16,000 BTU/hr/ft2. Thus, the failure mode of cargo tanks with an external fire may be due not to the vent system, but rather to heating of the unwetted wall. (Author)
