What Niovis Shipping does

Niovis Shipping Co. S.A. is a privately held, family-owned maritime ship management company headquartered in Piraeus, Greece, founded in 1972 by the Mavroleon family and now in its third generation of stewardship. The company operates as both a fleet owner/operator and a third-party ship manager, with a current fleet of 19 vessels comprising 16 Supramax and Ultramax dry bulk carriers (55,000–67,000 DWT), one Aframax tanker, one MR2 tanker, and one MR1 tanker. Average dry-fleet age is under 4.5 years, with vessels built at top-tier yards including Mitsui, DACKS, Hyundai Samho, Hyundai Mipo, Oshima, and NACKS.

The business generates revenue from two interlocking streams: chartering its own dry bulk and tanker tonnage to commodity shippers and traders on voyage and time-charter terms, and providing professional ship management services (operational, crew, safety, environmental compliance) to third-party vessel owners. Commercial and chartering execution is routed through an integrated network of affiliated companies: Bray Shipping Co. Ltd. (London-based agency, 1946), Bray Hellas Ltd. (shipbroking and sale-and-purchase), and Kinissis Navigation Ltd. (chartering). Distribution is direct to charterers globally, with vessels flagged in Greece and the Marshall Islands and trading worldwide.

Operating posture is conservative and compliance-led: USCG Qualship 21 certification covers eight vessels (placing the company in the top decile of foreign-flagged tonnage trading to the US), full INTERCARGO membership confers IMO-recognized standing, and the firm is a HELMEPA member and Neptune Declaration signatory. Pricing is not publicly disclosed; contracts are negotiated privately on cargo, route, duration, and prevailing market conditions. The company is GDPR-compliant, has no disclosed app or API product surface, and shows no AI/ML capability in its public footprint.
