Beneficial OwnerUnknown. The provided sources identify the company as part of Spring Marine Group / Spring Marine but do not disclose beneficial owners or a parent legal entity in the available results.[4][15][16]
SanctionsNone found. OpenSanctions reports the company is not found on international sanctions lists, and MagicPort screening also states it is currently not sanctioned.[1][9]

⚠ Red Flags

  • Fleet-size data is inconsistent across sources: one profile shows 5 managed vessels while another shows 28 and the company website states 27 operated vessels.[7][9][15][16]
  • Multiple address records exist for the same company across directories (Athens/Palaio Faliro vs Piraeus vs a Marshall Islands trust-company address in entity data), requiring source-by-source validation.[1][17]
  • OpenSanctions lists at least one vessel-related entity connected via 'c/o Spring Marine Management SA' (Merengue Shipping Co), which may warrant relationship review even though it is not a sanctions finding.[5]
