What Posidonia does

Posidonia Shipping is a privately held Brazilian maritime logistics operator founded in 2006 and headquartered in Barra da Tijuca, Rio de Janeiro, with regulatory authorizations from ANTAQ, ANP and IBAMA to conduct cabotage, long-haul and maritime support shipping including the transport of dangerous goods, crude oil, petroleum derivatives, petrochemicals and biofuels. It runs an integrated four-line service platform: (1) Maritime Cargo Transport covering both dry bulk (ores, grains, steel products, general and project cargo) and liquid bulk (crude oil, derivatives, chemicals, asphalt, biofuels, vegetable oils); (2) Ship Management for third-party vessel owners; (3) Offshore Support (Apoio Marítimo) with AHTS, PSVs and OSRVs serving oil & gas clients; and (4) Special Operations for project cargo such as ultra-heavy hydroelectric rotors, ro-ro machinery and wind turbine blades exceeding 60 meters.

The company's commercial platform spans owned vessels — including the PSV Posidonia Lion, AHTS Atlantic Kingfisher, the heavy-lift Posidonia Megatron (18,000 dwt), plus tankers, bulkers and tug/pusher units — alongside a chartered fleet exceeding 100 vessels per year and a managed fleet that includes large bulk carriers such as the Amazon Commander. Recent fleet additions include two PSV DP2 newbuilds (Posidonia Arlete and Posidonia Iara, 4,600 t deadweight each). Operational scale as disclosed on the company site reaches 15M+ tons of dry cargo and 28M+ cubic meters of liquid bulk transported annually, supported by 700+ qualified professionals across Operations, HSEQ, Technical, Finance, Legal, Administration and Commercial areas.

Posidonia operates a direct, sales-led B2B model targeting enterprise customers in energy, mining, petrochemicals and industrial logistics, with named clients including Petrobras, Shell, Galp, Vale, Alcoa, Arcelor, Braskem, Raízen, Ipiranga, Prio, Vibra and Modec. Revenue is generated through voyage/time charter fees, maritime transport contracts and ship-management service agreements; pricing is bespoke and not publicly disclosed. Capital structure relies on CVM-registered commercial notes (9th series issued in 2025) rather than equity issuance, consistent with apparent family ownership centered on the Ikonomopoulos leadership cohort alongside CEO Abrahão Salomão. The company is ISO 9001/14001/45001 certified by DNV and holds TRACE International, EcoVadis, DUNS & Bradstreet and UN Global Compact credentials.
