One (1) of the three (3) oiler positions required by the COI minimum safe manning is currently vacant, reportedly due to the oiler's STCW medical certificate (2 year period of validity) expiring during the voyage from Southampton (UK) to Baltimore, requiring him to off-sign from the vessel.
The vacant oiler position shall be filled and the COI minimum safe manning levels achieved prior to embarking on an international voyage (meaning prior to departure from Galveston for Altamira, Mexico, based on the vessel's reported upcoming port rotation).
Update 4/21/23: deficiency due date has been extended until the vessel's return to Baltimore, MD on/about 5/2/23; see activity # 7673016.

COI's minimum safe manning are currently filled/met.
The minimum manning required by the COI shall be

Each line is an incident investigation the Coast Guard recorded with this hull among the vessels involved, with the date and the classification the Coast Guard gave it, and the bridge, lock or dam the investigation names where it names one. Involvement is not fault. The investigation narrative is not published. Source: IIR, through 2026.
Ownership record
The Coast Guard's documentation record for this hull -- the Abstract of Title,
with its owners and liens as filed -- is not in PSIX. Ask, and Maury buys it from the National
