Chinese-Made Cranes at U.S. Ports: A National Security Threat

Introduction

Chinese-manufactured ship-to-shore cranes, predominantly produced by Shanghai Zhenhua Heavy Industries Company (ZPMC), have become a significant concern for U.S. national and economic security. Here is a comprehensive guide to the issues and implications associated with these cranes.

Dominance of ZPMC in the Global Market

• ZPMC holds an approximate 80% market share of ship-to-shore (STS) cranes operating in U.S. ports.
• This dominance is due to the competitive pricing and advanced technology of ZPMC cranes, which are often fully assembled and sealed upon delivery, integrating directly into port community platforms and other IT systems.

Cybersecurity and National Security Vulnerabilities

Backdoor Modems and Data Collection

• Recent investigations have revealed that these cranes contain cellular modems not requested by U.S. ports or included in contracts. These modems are connected to Linux computers on the cranes and are intended for collecting usage data, creating a significant backdoor security vulnerability.
• These modems can bypass firewalls and potentially disrupt port operations, posing a risk to the integrity of port infrastructure.

Remote Access and Control

• ZPMC has requested remote access to its STS cranes at various U.S. ports, particularly on the West Coast. If granted, this access could be extended to other PRC government entities, posing a significant risk due to China’s national security laws that mandate cooperation with state intelligence agencies.
• The ability to control, service, and program these cranes from remote locations raises concerns about potential espionage and cyber threats.

Integration with Critical Infrastructure

• These cranes handle sensitive data about containers, their contents, origins, and destinations, and integrate directly into port community platforms and other IT systems.
• The centralized network provided by these cranes can be used to acquire business intelligence and potentially manipulate U.S. maritime equipment and technology.

Potential Impact on U.S. Supply Chains and National Security

Disruption of Port Operations

• Malfunction or intentional shutdown of these cranes could cripple U.S. transportation capacity, leading to dangerous shortages and cascading supply chain failures.
• Such disruptions could severely impact commercial activities and hinder the Department of Defense’s ability to deploy supplies and resources, particularly in the Indo-Pacific region.

Geopolitical Implications

• China’s dominance in maritime infrastructure and its assertiveness, especially regarding Taiwan, raise concerns about the security of U.S. maritime supply chains.
• In a potential future dispute over Taiwan, the PRC could restrict or manipulate the supply of critical components or materials essential to U.S. maritime infrastructure.

Government and Industry Responses

Legislative and Regulatory Actions

• The 2023 National Defense Authorization Act required the Maritime Administration to lead an interagency study on the security threats posed by these cranes.
• The Coast Guard has ordered ports to implement better cybersecurity measures, including new cyber requirements for ship-to-shore cranes.

Alternative Manufacturing Initiatives

• Efforts are underway to start domestic production of ship-to-shore cranes in the U.S., in collaboration with Japanese heavy industrial companies, to reduce dependence on Chinese-made equipment.
• The Biden administration has called for investing billions of dollars in cranes to counter Beijing’s potential influence.

Industry Compliance and Challenges

• Despite the risks, commercial actors are reluctant to take actions that could cause operational or financial hardship due to their deep dependence on Chinese equipment.
• Ports and the shipping sector are facing increasing regulatory burdens, including rigorous inspections, control regimes over private assets, and costly replacement of ZPMC cranes.

Conclusion

The presence of Chinese-made cranes at U.S. ports poses significant cybersecurity and national security risks. Addressing these threats requires urgent action from both the government and industry stakeholders to ensure the integrity and security of U.S. maritime infrastructure and supply chains.

Frequently Asked Questions (FAQs)

What are the primary security concerns associated with Chinese-made ship-to-shore (STS) cranes in U.S. ports?

The primary security concerns with Chinese-made STS cranes revolve around their potential vulnerability to cyber exploitation. These cranes, predominantly manufactured by Shanghai Zhenhua Heavy Industries (ZPMC), are designed to be controlled, serviced, and programmed from remote locations, which leaves them open to potential cyber threats. The presence of cellular modems and other unauthorized components installed by ZPMC technicians raises fears that these cranes could be accessed and controlled by Chinese entities, posing a risk to U.S. port operations and national security.

Why are U.S. authorities recommending the disabling of modems and communications capabilities on Chinese STS cranes?

U.S. authorities, including the U.S. Coast Guard and Congressional committees, are recommending the disabling of modems and communications capabilities on Chinese STS cranes due to the discovery of suspicious device installations that are not part of the original contracts. These components, such as cellular modems, do not contribute to the operation of the cranes but could potentially allow for remote access by Chinese entities, thereby posing a significant cybersecurity risk. Disabling these capabilities is seen as a necessary step to prevent potential disruptions to port operations and protect U.S. critical infrastructure.

How are U.S. ports and the Biden administration responding to the security risks posed by Chinese STS cranes?

The U.S. ports and the Biden administration are taking several steps to address the security risks associated with Chinese STS cranes. The U.S. Coast Guard has issued a Maritime Security Directive requiring owners and operators of Chinese-made cranes to take specific actions to mitigate cyber risks. The Biden administration has also announced an Executive Order to strengthen maritime cybersecurity, which includes a $20 billion investment over five years to enhance U.S. port infrastructure and rebuild domestic industrial capacity for producing port cranes. Additionally, there are initiatives to support U.S.-based manufacturing of STS cranes to reduce dependence on Chinese-built cranes.

Do all experts agree that Chinese STS cranes pose a security risk?

Not all experts agree that Chinese STS cranes inherently pose a security risk. Some, like Cees Van Pelt from Rotterdam Shortsea Terminals, argue that with proper precautions, such as blocking access to terminal operations and using secure connections, the risk can be mitigated. The American Association of Port Authorities has also stated that there have been no recorded security breaches involving Chinese cranes in U.S. ports. However, U.S. national security officials and Congressional committees remain concerned about the potential vulnerabilities and the broader geopolitical implications of relying heavily on Chinese-made equipment.

What are the implications of the U.S. decision to impose tariffs on Chinese-made STS cranes and to invest in domestic crane manufacturing?

The U.S. decision to impose a 25% tariff on Chinese-made STS cranes and to invest in domestic crane manufacturing has significant implications. The tariffs aim to discourage the use of Chinese cranes and encourage the development of a domestic industry. This move is part of a broader strategy to reduce U.S. dependence on Chinese equipment and mitigate potential cybersecurity and national security risks. The investment in domestic manufacturing also reflects a long-term strategy to strengthen the U.S. industrial base and enhance the security and resilience of U.S. port infrastructure. However, this transition is expected to be costly and may take several years to implement, as Chinese cranes are currently significantly cheaper and more widely available.
