CITRINE MARINE SPC

CITRINE MARINE SPC is a UAE-registered shipping company identified by IMO Company Number 0138716. Available records identify it as the registered owner of oil tankers, including OASIS, and associate it with the transport of Russian crude oil and high-risk shipping practices.[1][3][5]

FleetAt least 6 vessels identified in available records; the complete fleet size is unknown. vessel(s)
Beneficial OwnerUnknown. Available records do not identify natural-person beneficial owners or a parent company. EU materials state that various CITRINE MARINE SPC tankers are managed by Nova Shipmanagement LLC-FZ and that the companies share a UAE address.[5]
SanctionsEuropean Union records identify CITRINE MARINE SPC as a UAE-based tanker owner associated with vessels transporting Russian crude oil, including for export, and describe its vessels as part of Russia's so-called shadow fleet and involved in irregular or high-risk shipping practices.[5] Ukrainian government records identify OASIS, ARROW, SPARTAN, BOBCAT, and AMAZON in shadow-fleet records and associate them with CITRINE MARINE SPC.[2][3][6][8][10] The available results do not establish a specific sanctions designation or enforcement action against CITRINE MARINE SPC itself.

⚠ Red Flags

  • Association with vessels described in official or government records as part of Russia's shadow fleet.[3][5]
  • Vessel ownership linked to transportation of Russian crude oil during applicable embargo and price-cap periods.[5][8]
  • Use of a C/O shipmanagement address and association with another Dubai-based shipmanager, Nova Shipmanagement LLC-FZ.[1][5]
  • Reported changes or differing records involving the company's management/address from Nova Shipmanagement LLC-FZ to Greenlight Shipmanagement FZE.[1][2]
  • Limited publicly available information on beneficial ownership.
🏢
GREENLIGHT SHIPMANAGEMENT FZE

Greenlight Shipmanagement FZE is a UAE-based maritime company identified by IMO Company Number 0164726. Available records identify it as a commercial and safety-management manager for multiple tankers, including OASIS as stated in the query, but the supplied search results do not establish its incorporation details, full business activities, or ownership.

FleetAt least 6 vessels reported in a KSE Institute Russian Oil Tracker publication, including five former Sovcomflot vessels transferred from Nova Shipmanagement LLC-FZ and one transferred from Moonlight Shipmanagement LLC in 2025. vessel(s)
Beneficial OwnerUnknown. The available results do not identify beneficial owners, parent companies, directors, or controlling shareholders. Ukrainian vessel records list Citrine Marine SPC c/o Greenlight Shipmanagement FZE as owner for several vessels, but this does not establish that Greenlight owns or controls Citrine Marine SPC.
SanctionsOpenSanctions indicates that Greenlight Shipmanagement FZE itself has not been found on international sanctions lists. However, Ukrainian government war-sanctions records identify Greenlight as commercial and safety-management manager for sanctioned or shadow-fleet vessels including CAVALIER, DISCOVERY, BOBCAT, and SPARTAN. The records state that related owners, operators, managers, executives, and senior crew may be subject to sanctions measures. A KSE Institute report states that the company operates six former Sovcomflot tankers and is actively operating former Sovcomflot vessels with North Fleet Ltd.

⚠ Red Flags

  • The company is recorded as manager of multiple vessels sanctioned or identified by Ukrainian authorities as part of a shadow fleet.
  • The company is reported to manage six former Sovcomflot tankers, linking its fleet activity to vessels previously associated with a sanctioned Russian state-owned shipping group.
  • Ukrainian records list Citrine Marine SPC c/o Greenlight Shipmanagement FZE as owner for several vessels, while the beneficial ownership relationship remains unverified.
  • The available evidence does not establish the company's beneficial owners, parent entity, directors, or full corporate structure.
  • The company appears in maritime sanctions-risk datasets even though OpenSanctions reports that the company itself has not been found on international sanctions lists.
