Fleet1 vessel(s)
Beneficial OwnerUnknown. The available sources identify SEA WOLF SHIPHOLDING CORP as the registered owner of SEA WOLF I and associate the company with Perosea Shipping Co. S.A., but do not disclose beneficial owners, shareholders, or a parent company.
SanctionsNo sanctions listing or enforcement action involving SEA WOLF SHIPHOLDING CORP was identified in the available sources. MagicPort reports that the company was not matched to its sanctions-watchlist screening and was not flagged as risky; this is not a substitute for official sanctions-screening databases.[10]

⚠ Red Flags

  • The shipowning entity uses the address of a separate ship-management company, Perosea Shipping Co. S.A., which is also associated with other shipowning entities.[1][7][10]
  • Publicly available sources do not identify the beneficial owners or corporate shareholders.
  • The company appears to have a single-vessel ownership structure, which limits publicly observable operating history.

Fleet16 vessels vessel(s)
Beneficial OwnerUnknown. The available sources identify PERTANKO MANAGEMENT SA as an ISM manager but do not disclose beneficial owners, parent companies, or a definitive corporate ownership structure. PEROSEA SHIPPING CO SA is identified as the commercial manager for several vessels managed by PERTANKO, but the sources do not establish ownership or control between the entities.
SanctionsNo sanctions, investigations, or enforcement actions involving PERTANKO MANAGEMENT SA were identified in the available sources. MagicPort reports that its screening against more than 300 international sanctions watchlists found the company not sanctioned. This is not a substitute for independent screening against current government sanctions lists.

⚠ Red Flags

  • The company operates through a network of separately named shipholding entities, including SEA WOLF SHIPHOLDING CORP, while PERTANKO is listed as ISM manager; this structure is common in shipping but limits transparency regarding ultimate ownership.
  • The same 22 Alkiviadou Street address is associated with more than one maritime company.
  • Beneficial ownership information was not identified in the available sources.
  • The reported fleet size and vessel-management roles are derived from commercial maritime databases and should be independently verified against current flag-state, class, registry, and sanctions records.
