Desalination plants create drinkable freshwater from ocean water in areas where there are not sufficient supplies of freshwater.Subsea pipelines are considered to be the most efficient and economical way to transport liquids from offshore to land or other areas. Loads on a marine pipelines can bedivided into the categories: functional, environmental, accidental and installation loads [1]. A marine pipeline is exposed to different loads during installation such astension, bending, and high external hydrostatic pressures which are becoming greater problems in increasing water depths. Pipeline installation process of SAKO desalinationplant is numerically analyzed in this paper using OrcaFlex software
