It is unclear if either O Hak San or O Ka San is a misspelled version of the name. A search on Equasis does not yield any names used prior to "SUNTUDSAMUT 4" since June 2018. The name "Dae Dong Gang" yields no result on Equasis. The alternate spelling "Tae Dong Gang" can be found and associated with the IMO 7738656. However, both the "Dae Dong Gang" and the "Tae Dong Gang" are listed in Annex XXXI (p. 111) of the UN Panel of Experts March 2014 report.
