HONG KONG EASTRELIANT SHUNWAY

HONG KONG EASTRELIANT SHUNWAY is a Hong Kong-linked maritime owning entity based in Qingdao, China, and is identified as the registered owner of the crude oil tanker COSMO SAIL. Available vessel databases indicate it is a single-vessel owner/manager structure, with operational management handled by Taihu Shipping Co Ltd.

Fleet1 vessel(s)
SanctionsThe company was listed as the ship owner of COSMO SAIL in Ukraine’s War & Sanctions database, and COSMO SAIL itself was added to Ukraine sanctions on 2026-02-12. No additional sanctions, investigations, or enforcement actions specific to HONG KONG EASTRELIANT SHUNWAY or its principals were found in the available sources.

⚠ Red Flags

  • Single-vessel ownership/management profile
  • Uses c/o address at Taihu Shipping Co Ltd in Qingdao
  • Company associated with a vessel designated by Ukraine as part of the shadow fleet
  • COSMO SAIL reported as transporting Russian crude oil under sanctions pressure
🏢
TAIHU SHIPPING CO LTD

TAIHU SHIPPING CO LTD is a China-based maritime ship manager with a listed address in Qingdao, Shandong. Public vessel databases identify it as the commercial manager and ISM manager of the crude oil tanker COSMO SAIL, and a maritime database describes it as managing a fleet of 1 vessel.[1][2][3]

Fleet1 vessel(s)
Beneficial OwnerUnknown. Public vessel records identify the registered owner of COSMO SAIL as HONG KONG EASTRELIANT SHUNWAY, while TAIHU SHIPPING CO LTD is listed as commercial/ISM manager; no verified beneficial owner or parent company was found in the available sources.[1][2]
SanctionsCOSMO SAIL was designated by Ukraine in February 2026 for sanctions-related shadow fleet activity involving transport of Russian crude oil, and public sanctions records list TAIHU SHIPPING CO LTD as the vessel’s commercial and ship safety management manager as of 2025-10-23.[1] No separate sanctions action against TAIHU SHIPPING CO LTD itself was found in the available records.

⚠ Red Flags

  • Manager of a vessel designated by Ukraine as part of the shadow fleet.[1]
  • Company is listed as commercial manager and ISM manager for COSMO SAIL, while the registered owner is a separate Hong Kong entity.[1][2]
  • Fleet appears very small and concentrated in a single 2007-built tanker, which can increase transparency and counterparty concentration risk.[2][3]
🏢

Fleetunknown vessel(s)
Beneficial OwnerUnknown. Retrieved vessel databases identify COSMO SAIL’s registered owner as Hong Kong Eastreliant Shunway Industrial Co Ltd and the commercial/ISM manager as Taihu Shipping Co Ltd; no direct beneficial owner information for HAO XIN LONG LTD was found in the available sources.
