Joint Investigation into CCP-Backed Company Supplying …
Joint Investigation into CCP-Backed Company Supplying Cranes to U.S. Ports: Key Findings and Implications
Introduction
A joint investigation by several House committees has uncovered significant concerns regarding Chinese-built cargo cranes deployed at various U.S. ports. The investigation, focusing on cranes supplied by Shanghai Zhenhua Heavy Industries (ZPMC), a state-owned Chinese manufacturer, has revealed several alarming findings that raise national security concerns.
Discovery of Unauthorized Communications Equipment
- Cellular Modems: The investigation found cellular modems installed on ZPMC ship-to-shore (STS) crane components at multiple U.S. seaports. These modems were not part of the original equipment contracts and were discovered in places such as crane components and server rooms housing the cranes’ firewall and networking equipment.
- Unrequested Installations: Several ports reported that these modems were installed without their request or knowledge. When U.S. port personnel inspected the cranes in China, the modems were already installed.
Security Concerns
- Potential for Spying: The presence of these unauthorized cellular modems has fueled concerns within the Biden administration that these cranes could be used for spying on U.S. ports. This is particularly worrisome given ZPMC’s ties to the Chinese Communist Party (CCP).
- Historical Precedents: In 2021, the Federal Bureau of Investigation (FBI) discovered intelligence gathering equipment on a vessel delivering ZPMC cranes to the Port of Baltimore, further exacerbating these concerns.
ZPMC’s Dominance and CCP Connections
- Market Dominance: ZPMC accounts for nearly 80 percent of the STS cranes in use at U.S. maritime ports. This dominance raises significant security and dependency issues.
- Proximity to PLA Facilities: Many of these cranes are built in an area adjacent to a shipyard where the People’s Liberation Army Navy’s most advanced warships are constructed, including the PRC’s third aircraft carrier and its fleet of Type 055 and Type 052 destroyers.
- Engagement with CCP: The investigation is also examining ZPMC’s engagement with the CCP and any requests from the CCP to ZPMC, highlighting the potential for state-directed activities.
Involvement of Other Companies
- ABB: The investigation includes the Swiss company ABB, as many of the operational components manufactured by ABB are shipped to China, stored for several months, and then installed onto U.S.-bound port equipment by ZPMC engineers.
Operational and Security Implications
- Remote Monitoring: While some of the cellular modems were used for legitimate operational functions such as remote monitoring and maintenance tracking, others were installed without any clear purpose or request from the ports.
- National Security Risk: The unauthorized installation of these devices poses a significant national security risk, as they could potentially be used for surveillance or sabotage.
Conclusion
The findings of this joint investigation underscore the critical need for enhanced scrutiny and oversight of foreign-made equipment, particularly those with potential ties to adversarial nations. The presence of unauthorized communications equipment on ZPMC cranes highlights the vulnerabilities in U.S. port security and necessitates immediate action to mitigate these risks and ensure the integrity of U.S. national security.

Frequently Asked Questions (FAQs)
What is the primary security concern regarding Chinese-made container cranes in U.S. ports?
The primary security concern surrounding Chinese-made container cranes in U.S. ports is their potential vulnerability to exploitation by the Chinese government for surveillance and cyber disruption. These cranes, predominantly manufactured by Shanghai Zhenhua Heavy Industries Co. (ZPMC), can be controlled, serviced, and programmed from remote locations, which leaves them open to being hacked or used for spying. This vulnerability could compromise sensitive data about containers, their contents, origins, and destinations, including military shipments, and potentially disrupt critical infrastructure and supply chains.
How widespread are Chinese-made container cranes in U.S. ports?
Chinese-made container cranes are extremely prevalent in U.S. ports, with ZPMC cranes accounting for nearly 80% of the ship-to-shore (STS) cranes in use. This dominance is due to China’s significant market share and the competitive pricing of these cranes, which are often half the cost of those manufactured in the United States. Over 200 of these cranes are currently operating in U.S. ports, highlighting the extensive reliance on Chinese-manufactured equipment.
What measures are being taken to address the cybersecurity risks associated with these cranes?
To mitigate the cybersecurity risks, the U.S. Coast Guard has issued Maritime Security Directive 105-4, which outlines required cyber-risk management actions for owners and operators of Chinese-made STS cranes. This directive includes specific security measures and requires immediate contact with local captains of the port or district commanders to obtain the directive. Additionally, the U.S. government is proposing new cybersecurity requirements for U.S.-flagged vessels, ports, and container terminal operators, including minimum requirements for cybersecurity plans. There are also efforts to segment networks and use Cross Domain Solutions (CDS) and Content Disarm and Reconstruction (CDR) to protect sensitive data and prevent cyber threats.
What are the potential consequences of a cyberattack on these cranes?
A cyberattack on Chinese-made container cranes could have catastrophic economic and security consequences. The operational technology (OT) systems of these cranes could be exploited to completely shut down domestic port operations, suspending all commercial activity and disrupting both military and commercial supply chains. This could provide opportunities for near-peer nation-state adversaries, such as China, to cripple the U.S. economy. The impact would be felt across the entire supply chain, affecting over $5.4 trillion in economic activity and more than 90% of overseas trade moving through U.S. ports.
What long-term solutions are being considered to reduce dependence on Chinese-made cranes?
The U.S. government is exploring long-term solutions to reduce dependence on Chinese-made cranes by incentivizing the onshoring of crane manufacturing. This includes a significant economic inducement of $20 billion to support the establishment of new manufacturing facilities in the United States. For instance, a major grant has been allocated to PACECO Corp., a U.S. subsidiary of a Japanese industrial conglomerate, to set up a new facility and partner with other international firms to revitalize U.S.-based manufacturing capabilities that have been absent for decades. The proposed Crane Reshoring and National Enforcement of Supply Chain Security (CRANES) Act of 2023 also aims to jump-start American production of new port container handling equipment.
