ALEXANDER TANKERS SHIPPING

ALEXANDER TANKERS SHIPPING CORP. is a Marshall Islands-based maritime company identified as the ship owner for the tanker ALEXANDER/ALIMEDON in maritime sanctions-related records. It appears to function as a vessel-owning entity within a tanker ownership/management structure rather than as a large diversified shipping group.

Fleet1 known vessel; otherwise unknown vessel(s)
SanctionsThe company appears in Ukrainian GUR war-sanctions listings as the ship owner for ALIMEDON (IMO 9826720), a vessel categorized for transporting Russian crude oil/petroleum products in violation-related sanctions context. No separate enforcement action against the company itself was found in the available records.

⚠ Red Flags

  • Listed as ship owner for a vessel appearing in sanctions/shadow-fleet related records
  • Marshall Islands offshore registration with limited transparency on ownership
  • Single-vessel ownership structure indicated by available records
🏢
EXECUTIVE SHIP MANAGEMENT

Executive Ship Management Pte Ltd is a Singapore-based ship management company headquartered at 78 Shenton Way and identified by IMO company number 1834165. Publicly available records show it serves as ISM/safety management or technical manager for multiple vessels, including the tanker ALEXANDER (IMO 9826720), and it states that it has offices in multiple cities worldwide.

Fleet101 vessel(s)
SanctionsOpenSanctions indicates no match on international sanctions lists. However, Ukrainian state war-sanctions sources list Executive Ship Management Pte Ltd as the ship safety management manager for vessels identified as part of the shadow fleet, including ALIMEDON and AFRAMAX RIVIERA, and associate ALEXANDER with a vessel that changed ownership and management after sanctions on Sovcomflot in 2022. Canada also recorded an administrative enforcement action against Executive Ship Management PTE. LTD. in 2024 for a marine pollution/dangerous chemicals violation.

⚠ Red Flags

  • Named by Ukrainian war-sanctions authorities in connection with shadow-fleet vessels
  • Canadian administrative enforcement action in 2024 for a pollution/dangerous chemicals compliance violation
  • Fleet associated with a vessel structure involving separate owner and commercial manager entities for ALEXANDER
  • Shared Singapore corporate address used by maritime companies
🏢

Fleet2 vessels vessel(s)
Beneficial OwnerUnknown. Public vessel records show commercial management by Sealion Tankers Inc and registered ownership by single-ship entities such as Polo Crude Carriers SA and Nimus Crude Carriers SA, but no beneficial owner of Sealion Tankers Inc was identified in the gathered sources.
SanctionsThe company appears in Ukraine’s war sanctions/shadow fleet maritime listings as a commercial ship manager connected to vessels used in Russian crude oil trade. No separate enforcement action against the company itself was found in the gathered sources.

⚠ Red Flags

  • Listed in shadow-fleet/sanctions-related maritime databases
  • Commercial manager of crude oil tankers linked to Russian crude trade
  • Uses a single office address for tanker management and correspondence
  • Corporate structure relies on single-ship owning entities rather than an identified operating parent
