They did engage a "professional" engineering house to do the design. Unfortunately, the basis of this design seems flawed, or the engineering outcomes required from this basis were misinterpreted. While the result has put tremendous strain on the company, the reasons the basis was flawed are never so clear. You can't just claim a "guarantee". Nevertheless, engineering companies carry professional indemnity insurance which could (should?) be tested at some future point - but it would be a mistake of management to focus on that now instead of trying to resolve the situation and get the plant back up. Park it and circle back next year when things are better....
