A professional computing tool specially designed for submarine cable and underground cable laying engineering. This application integrates all-round engineering calculation functions needed in cable installation process, and helps engineers to quickly and accurately complete complex construction parameter analysis. Core functions: Tension calculation-real-time monitoring of tension parameters during cable laying to ensure construction safety. Bending radius analysis-Accurate calculation of cable bending limit to avoid mechanical damage. Friction calculation of chute-optimization of friction coefficient and force analysis of cable passing through chute Route planning-intelligently plan the cable laying path and optimize the construction scheme. Thermal expansion calculation-evaluate the influence of temperature change on cable length Burying energy analysis-calculate the energy parameters needed for seabed or underground burial. Project data management-supports multi-project data storage and management, and facilitates project traceability.
