About This Item
IEEE 1120-1990 is a technical guide for planning, designing, and installing submarine power and communications cables. It addresses the factors that influence cable selection, route planning, mechanical protection, and installation practices in underwater environments. For power, energy, and communications projects, this standard helps engineers and project teams reduce installation risk, improve reliability, and make informed decisions where underwater cable systems face demanding physical and operational conditions.
Overview of IEEE 1120-1990
This standard provides guidance for the engineering considerations involved in submarine cable projects, with attention to both power transmission and communications applications. IEEE 1120-1990 is intended to support consistent planning and installation decisions where cable systems must operate beneath water and remain protected against environmental and mechanical stresses. Its scope is practical and project-oriented, making it useful when evaluating cable routes, installation methods, and the factors that affect long-term service performance.
Typical use cases
Common applications include offshore power connections, inter-island links, harbor and coastal installations, and underwater communications routes. The standard is relevant when teams are assessing seabed conditions, cable laying methods, burial or protection needs, and interfaces with landing points or shore approaches. It may also support specifications for utility projects, marine infrastructure work, and engineering reviews where submarine cable reliability and installation control are important.
Why it matters
Submarine cable projects involve high costs, difficult access, and significant consequences if installation is poorly planned. IEEE 1120-1990 helps structure decision-making around design, installation, and protection so that performance expectations are realistic and risks are better controlled. Using a recognized guide can support procurement clarity, technical review, and compliance efforts while reducing the chance of damage, premature failure, or avoidable maintenance in service.
