SIMPLEX AMERICAS LLC

SIMPLEX AMERICAS LLC specializes in the design, manufacturing, and overhaul of critical marine propulsion and sealing systems for U.S. Navy auxiliary vessels. Their core capabilities center on the fabrication and installation of stern tube seals, gaskets, and precision sealing devices used in shipboard propulsion shaft systems, ensuring watertight integrity under extreme hydrodynamic loads. The contractor demonstrates deep technical expertise in marine mechanical systems, particularly in the repair and sustainment of fleet oilers and replenishment ships, with direct experience in retrofitting and replacing high-pressure sealing components for submerged driveline assemblies. Their work requires strict adherence to naval engineering standards, material compatibility with seawater and lubricants, and tolerance control for rotating shaft interfaces—key differentiators in mission-critical naval maintenance environments. The company maintains a consistent relationship with the Department of Defense, delivering specialized components and overhaul services for Navy fleet support ships, including T-AO class fleet replenishment oilers. Their work supports vessel availability and operational readiness by addressing wear-prone sealing systems that directly impact propulsion system reliability and hull integrity. SIMPLEX AMERICAS LLC operates primarily within NAICS 336611 (Ship Building and Repairing) and 339991 (Gasket, Packing, and Sealing Device Manufacturing), positioning itself as a niche supplier of mission-specific marine sealing solutions rather than a general shipbuilder. They serve the naval surface fleet’s sustainment market with engineered components that replace proprietary or obsolete parts, often requiring reverse engineering and material substitution under strict military specifications. As a small business structured as a 2L entity based in Flemington, New Jersey, SIMPLEX AMERICAS LLC lacks federal certifications but maintains focused technical capabilities aligned with DoD maritime maintenance needs. Their geographic proximity to East Coast naval infrastructure supports rapid response and logistics coordination for scheduled dry-dock overhauls and emergency repairs.
