During these fire tests (both IMO L1 and IMO L2), a serious flaw in the test setup has been discovered that causes a disproportionate amount of fire protection in order to reach two relatively simple requires defined as “no leakage” during fire testing (Nitrogen) and water pressure test at rated pressure after the first test.

 

This inherent flaw is uncovered because Favuseal has, in consultation with SINTEF/SP including a variety of temperature sensors that are not defined in the IMO. The inclusion of these additional temperature sensors does not inflict or impair the fire test performed…
