Hello David,
Herakles was laid up at Swinoujsce for a couple of years, but reactivated in the summer of 2018 for a bridge project in Greenland. Then back into lay-up again.
Hermes is known for buying ocean going tugs, using them once or twice for a tow and then scrapping them.
Does not look good for the old Salvageman.
Best wishes,
Hans
