Ah, here’s the IMO database entry on the MV Aman. It provides much additional context. https://www.ilo.org/dyn/seafarers/seafarersbrowse.details?p_...

In particular, here’s a recent update that sheds some light on why Mr. Aisha remained aboard - in short, he refused to leave unless and until he was paid the wages due to him:

  Govt. of Bahrain (7 March 2021)
  From Registration of Ships & Seamen Affairs
  I would like to highlight few facts as below:
  1) Vessel is not abandoned, but under court arrest due to ongoing cases.
  2) Seafarer by the name Mohamed Aisha had accepted a court appointment to act as court representative onboard. As such, when the owner repatriated all other crew members he was not allowed to be repatriated by the courts. 
  3) We had intervened with owner several time and also arranged for the courts to allow his repatriation by appointing another representative, but he decided not to disembark due to outstanding wages.
  4) The owners have tried with all resources available to repatriate him but he was not willing to cooperate.

  If he is now ready to be repatriated, then the owners are willing to cover such costs of air passage and local charges as a show of our commitment towards him.
