The course emphasises the importance of undersea CI, such as internet and telecommunication cables, power transmission lines, oil and gas production systems, and scientific research equipment. It highlights the strategic significance of undersea cables, which carry over 95% of international data, and the challenges in protecting them from threats.   The course also discusses the legal frameworks applicable to undersea CI, including national and international laws, and the responsibilities of owners and operators. Additionally, it covers the different types of undersea platforms, such as submarines, remotely operated vehicles (ROVs), and autonomous underwater vehicles (AUVs), and their roles in supporting CI. The course includes maps and diagrams to illustrate the locations and structures of undersea CI, as well as the deployment and support systems used in undersea operations. --- ## Intended Audience This course is suitable for personnel that require an awareness of types of critical Undersea Infrastructure, and the techniques used to disrupt and also protect such systems. --- ## Course Modules - Describe Undersea Critical Infrastructure (CI) - Describe Vulnerability of Undersea CI. - Describe undersea platforms that support CI - Describe the laws applicable to CI - Understand how Undersea CI is manufactured, deployed and maintained - Describe Military operations preparing for, deterring, and defending against threats to CI --- **Course price:** AUD$715 inc GST ![Critical Underwater Infrastructure (CUI) - MC005](https://soio.com.au/hs-fs/hubfs/sea-8344717_1280.jpg?width=1280&height=851&name=sea-8344717_1280.jpg "Critical Underwater Infrastructure (CUI) - MC005") For multiple course seat bookings, please call Kerry Houston on 0439 997 719 [![SOIO\_Logo\_Rev-3](https://soio.com.au/hs-fs/hubfs/SOIO_Logo_Rev-3.png?width=200&height=41&name=SOIO_Logo_Rev-3.png "SOIO_Logo_Rev-3")](http:/?hsLang=en) SCHOOL OF INFORMATION OPERATIONS         ABN 62 624 905 399 © 2026 All rights reserved.     ###### CONTACT US PO Box 503 Prospect East, SA 5082 Australia +61 417 742 705   [Follow us on LinkedIn](https://www.linkedin.com/company/school-of-information-operations/) [Email us](mailto:info@soio.com.au) [Follow us on Facebook](https://www.youtube.com/@SOIOTraining) ###### SUBSCRIBE TO OUR MAILING LIST ###### [QUAD CHART](https://soio.com.au/hubfs/260318%20SOIO%20Quad%20Chart.pdf?hsLang=en) ###### [CONTACT](https://soio.com.au/contact?hsLang=en) ###### [PRIVACY POLICY](https://soio.com.au/privacy-policy?hsLang=en) ###### [PRIVACY COLLECTION NOTICE](https://soio.com.au/privacy-collection-notice?hsLang=en) ###### [FEES](https://soio.com.au/privacy-collection-notice-0?hsLang=en) ###### [ABOUT](https://soio.com.au/about-the-school-of-information-operations-soio?hsLang=en) ###### [NEWS](https://soio.com.au/news?hsLang=en) ###### [TERMS & CONDITIONS](https://soio.com.au/terms-conditions?hsLang=en)
