What Master Marine does

Master Marine Comércio e Exportação Ltda., doing business as Master Marine, is a privately held Brazilian ship supply company headquartered in Santos, São Paulo. Founded in 1949 as Mansueto Pierotti & Filhos Ltda. and operating under the Master Marine name since 1965 (with full operations assumed in 2013), the firm is now in its third generation of Pierotti family ownership, led by Eugênio Pierotti (President), Flavio Pierotti (CEO), Renata Pierotti (CFO), and Fernanda Pierotti (ESG Director). The company provides bonded stores, consumable stores, and food provisions to commercial vessels — including container ships, freighters, tankers, offshore tugs, and cruise lines — operating across eight ports in Southeast Brazil (Santos, São Sebastião, Paranaguá, Rio de Janeiro, Itaguaí, Sepetiba, Guaíba, Angra dos Reis), with PETROBRÁS identified as a priority customer.

The company's product portfolio is organized into six categories: beverages and food (dry, fresh, chilled, and frozen); cleaning materials; certified publications and nautical charts; deck and engine supplies; chemicals; and gas handling. Master Marine owns and operates a fleet of eight specialized trucks, including a Mercedes 2426 refrigerated unit with independent cooling, automatic defrost, and remote cell-phone monitoring. The firm was the first ship supply company in Brazil to obtain HACCP food safety certification and holds ISO 9001:2015 quality management certification (achieved May 2018). It is a member of ISSA, WISTA, ABFN, and IMPA, providing global industry credibility.

Revenue is generated through direct, quote-based per-vessel supply contracts, with no publicly disclosed pricing. The go-to-market is enterprise field sales executed through the company's own port-side delivery infrastructure. The firm employs 11–50 people, has no external investors, no subsidiaries, and no disclosed funding; it operates as a self-funded, multi-generational regional logistics business with limited public financial disclosure.
