Maran Tankers Management

What Maran Tankers Management does

Maran Tankers Management ("MTM") is the oil tanker shipping management unit of the Angelicoussis Group, a privately held, family-controlled Greek shipping conglomerate with roots dating to 1947. Founded in 1992 and headquartered in Kallitéa, Athens, MTM manages a fleet of 50 oil tankers with 13 additional vessels on order, totaling 13,081,403 DWT of active capacity and an average fleet age of 9 years — meaningfully younger than industry norms. The company operates a single-segment, asset-heavy tanker management business that annually transports approximately 139 million metric tons of cargo across roughly 155 port calls (per firmographic data; company website cites 1,446 port calls annually) and 3.35 million nautical miles.

MTM delivers an integrated eight-line service stack: Technical Management, Operations, Performance, Crewing, HSQE (Health, Safety, Quality, Environmental), Chartering, Training, and Newbuildings. Revenue is generated on a transaction-fee basis through direct B2B chartering relationships with oil companies, commodity traders, and energy sector clients requiring seaborne crude oil and petroleum product transportation. The GTM motion is sales-led, targeting enterprise energy clients across global tanker markets through direct corporate engagement and maritime industry presence rather than through intermediary channels. Pricing is quote-based and not publicly disclosed. The company employs over 8,000 seafarers and shore-based professionals worldwide.

Technology adoption includes the Orca AI Co-Captain real-time navigation platform (connecting to a 1,000-ship network for hazard, weather, and compliance intelligence), a five-year aftermarket service agreement with Nikkiso for high-pressure pump systems, and active participation in a nuclear propulsion feasibility study targeting the first commercial nuclear-powered tanker by 2035. Customer concentration is concentrated among major oil companies and commodity trading houses, with limited public disclosure of specific charterers beyond CPC Terminal (Kazakhstan) references.
