Ownership & Management
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]
⚠ 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 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.
⚠ 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.
