Towing vessel under charter? Don’t let it cause a break in the safety system

‘Findings of Concern’ focuses on the hazards of corrosion

The Coast Guard issues findings of concern to disseminate information related to unsafe conditions identified as causal factors in a marine casualty and that may cause a similar casualty on other vessels. Findings of concern are intended to educate the public, state, or local agencies about the conditions discovered so they may address the findings with an appropriate voluntary action or highlight existing applicable company policies or state/local regulations.
