What Nanjing High Accurate Marine Equipment Co. does

Nanjing High Accurate Marine Equipment Co. (NGC Marine) is a Chinese marine propulsion and industrial transmission equipment manufacturer, spun off in 2007 from NGC Group (南高齿 / China Transmission) to consolidate the parent's 50+ years of gear-engineering heritage. The company designs and manufactures a full portfolio of marine propulsion systems — controllable pitch propellers (NCP), azimuth thrusters (NRP, NRPL, NTRP, NRRP, NDRP), electric pods, side thrusters, and PTI hybrid propulsion units — alongside industrial gearboxes for steel, cement, mining, and power generation applications. Its 160,000 sqm Nanjing manufacturing facility produces 1,000+ propulsion and transmission units per year, with cumulative deliveries of 6,000+ gearboxes, 1,500+ side thrusters, and 1,000+ azimuth thrusters supporting 1,000+ ship exports globally.

The business is structured as a private B2B enterprise with quote-based project pricing, multi-year contracts, and direct sales coverage across seven domestic Chinese regions plus four wholly-owned international subsidiaries (Singapore as SEA HQ, Malaysia, Fort Worth USA, Duisburg Germany) and agent networks in 14+ additional countries. The company is the only qualified Chinese gearbox supplier approved by Rolls-Royce, MAN Energy Solutions, and Wartsila for main propulsion gearboxes, and holds certifications from all major ship classification societies (CCS, BV, DNV, ABS, LR, NK, KR, RMRS, RINA) plus IRS, with 200+ patents and 40+ technology awards supporting the technical positioning. Recent product launches include China's first oil-electric hybrid tugboat propulsion (2023), 1,600-ton offshore wind installation platform lifting gearboxes (2022), and a 6,300m³ LPG/ammonia carrier CPP system (2025), signaling a strategic shift into new-energy marine propulsion and offshore wind verticals alongside the 2026-reported pivot from domestic to export-oriented revenue mix.
