  • Sewage Treatment Plant (STP) – Processes black and grey water before overboard discharge.
  • Exhaust Gas Cleaning System (Scrubber) – Reduces sulfur oxides (SOx) emissions to comply with IMO 2020 regulations.

🛑 Potential Risks: Non-compliance, equipment clogging, chemical exposure.
✅ Risk Management: Routine maintenance, regulatory audits, system automation.

6. Communication & IT Systems (Vessel Connectivity & Cybersecurity)

📌 Facilitating onboard and shore-based communication.

  • Integrated Shipboard IT Network – Provides seamless communication between ship systems and crew.
  • Satellite Broadband (VSAT, LEO, Inmarsat, Starlink Maritime) – Enables high-speed connectivity at sea.
  • Cyber Intrusion Detection & Prevention System (IDPS) – Monitors for unauthorized access to ship networks.
  • Remote Ship Monitoring & Diagnostics – Allows shore-based teams to assess system performance in real-time.
  • Electronic Chart Display and Information System (ECDIS) Updates – Ensures compliance with the latest chart updates.
  • Emergency Position Indicating Radio Beacon (EPIRB) – Sends distress signals in case of abandonment.

🛑 Potential Risks: Signal loss, hacking, outdated navigation charts.
✅ Risk Management: Encrypted communications, firewall systems, backup data storage.

7. Crew Welfare & Habitability Systems (Enhancing Crew Comfort & Efficiency)

📌 Ensuring a livable and safe environment onboard.

  • Crew Fatigue Monitoring System – Tracks working hours and rest periods to prevent fatigue-related accidents.
  • Smart HVAC System – Provides adaptive temperature and humidity control in crew quarters.
  • Vibration & Noise Control Systems – Reduces exposure to machinery noise for crew health.

[MaritimeCyberTrend] Relationship and prospects between U.S. Chinese maritime operations and maritime cybersecurity

Image
U.S. Sanctions on Chinese Ships & Cybersecurity Compliance The U.S. Trade Representative (USTR)’s sanctions on Chinese shipping and shipbuilding are expected to heighten the importance of cybersecurity regulations in vessel operations. In particular, as the U.S. increasingly frames Chinese-built ships and shipping companies as cybersecurity risks, compliance with maritime cybersecurity standards will become a critical issue for global shipping stakeholders. The United States is increasingly likely to classify Chinese-built vessels as national security and cybersecurity threats, using this as a basis for additional regulations and sanctions. In particular, drawing from past sanctions on Huawei and ZTE, the U.S. may argue that ships built in Chinese shipyards and equipped with Chinese IT systems (navigation, communication, and monitoring equipment) pose risks to the digital maritime infrastructure of the U.S. and its allies. As a result, the U.S. Coast Guard (USCG) is expected to s...
