Determining the installation conditions of submarine cables and evaluating the relevant parameters are important issues in the subject about laying of submarine cables. Based on the catenary theory and the lumped mass method, this paper adopts a simplified model to dynamically simulate the cable’s normal laying process. According to the 3 acceptance criteria, the method for determining the environment conditions of cable installation is clarified, and the sensitivity analysis for the main influence factors is conducted. Finally, it concluded the suitable environment conditions for normal laying of the submarine cable.
