Shihang Intelligent

What Shihang Intelligent does

Shihang Intelligent (世航智能), branded internationally as SEAHI Robotics, is a marine robotics company founded in October 2023 and headquartered in Kunshan (Suzhou), China. It designs, manufactures, and operates autonomous underwater and surface robots for port operators, shipping companies, energy groups, and government agencies, with operations spanning 20+ ports across China, Hong Kong, Singapore, and exploratory entry into the Middle East. Its product platform centers on the 虎鲸 (Orca) general-purpose underwater robot capable of 0–10,000 m full-depth operations, the 虎鲨 (Tiger Shark) surface robot, the SEAHI X deep-sea prospecting unit, the lightweight 虎鲸 Mini, and the proprietary 盘古 (Pangu) thruster series — all unified by six self-developed core systems (propulsion, control, sensing, navigation, waterproof sealing, deployment/recovery) and governed by the 沧穹 (Cangqiong / CEORION) ocean embodied large model trained on millions of hours of real commercial ocean operations data.

The company monetizes through three streams: (1) hardware sales of marine robots and Pangu thrusters to enterprise and government buyers; (2) robot-as-a-service (RaaS) field operations where Shihang deploys its own fleet and trained operators to perform underwater hull cleaning and inspection at customer ports on per-vessel or per-operation contracts; and (3) customized industry solutions (offshore solar, offshore wind, marine ranching, deep-sea resource exploration) typically won through competitive tendering. Pricing is custom-quoted by enterprise deal, with no public price tiers. Named enterprise customers include China Merchants Shipping, COSCO Bulk, Shandong Port Group, China Nuclear Power Group (CGN), National Energy Group Port, Fujian Marine Shipping Group, and undisclosed major international ports plus Singapore and Hong Kong shipping counterparts — alongside selection into Singapore MPA's national underwater hull inspection and cleaning plan (CFP).

The business is anchored in deep regulatory and standards leadership (Shihang led drafting of China's first underwater cleaning robot operational standard with the Ministry of Transport, CCS, China Merchants Shipping, Shandong Port and others) and a capital base exceeding 1 billion RMB (~$148M) raised across angel through Series A rounds by 2026, with the Series A alone being described as the largest single financing round in the global marine robotics sector. Backers include Vertex Growth (Temasek), Vertex Ventures China, GSR Ventures, Shanghe Momentum Fund (Moore Threads / Kunlun AI Chip industrial arm), CITIC Group, Huaying Capital (manager of the National SME Development Fund), China Merchants Startup Capital, and others; the company holds 400+ IP rights and is classified as a national high-tech enterprise, Jiangsu potential unicorn, and Beijing IP pilot advantage unit.

Its AUV business is directly comparable to Shihang's Orca/SEAHI X deep-sea platforms, while its broader portfolio (bridge systems, propulsion) overlaps with Shihang's thrusters and navigation stack.

Regional players

• Subsea 7: Subsea 7 is a global subsea engineering, construction, and services contractor operating ROV fleets for offshore oil & gas and renewables projects. While its focus is on subsea construction rather than mass-market ship cleaning, it addresses the same enterprise customer base (shipping, offshore wind, ports) and competes indirectly for inspection/maintenance contracts.
