Bulk carrier disabled in English Channel, curious salvage

Bulk carrier SEA HERMES reported propulsion failure at 2030 UTC Feb 22 in English Channel north of Cape Gris-Nez, Pas-de-Calais, France. Attempts to fix the problem by crew means failed, SAR ship ABEILLE LANGUEDOC was designated to tow bulk carrier to UK waters, at around 0100 UTC Feb 23 French pilot and a standby Captain from ABEILLE LANGUEDOC were transferred on board of bulk carrier by helicopter – absolutely unclear why, and what specific circumstances demanded deployment of pilot and Captain from another ship. Towage commenced at 0840 UTC Feb 23, pilot was taken off the ship by helicopter, standby Captain remained on board. At 1330 UTC Feb 23, both ships were laying dead in water east of Dover UK, ABEILLE LANGUEDOC apparently disengaged from towing. Probably, bulk carrier is in process of anchoring.
Why by the way, French MRCC Gros-Nez, wrote in press-release, that the ship is Panama-flagged, and is en route from Spain?
Bulk carrier SEA HERMES is en route from Argentina to Gdynia Poland.
