No, the Manager is not accusing the Shipyard of "possible liability issues" but warning of "possible action in regard to liability for damages".
I'm not sure a Manager can charge a Shipyard with anything. They can certainly warn them that they intend suing for damages.

But I'm not sure whether you are trying to understand what a certain sentence means, or you know what it is supposed to mean, and are trying to work out how to say it.
