| Summary: | <p align="justify">In the process of subsea pipeline design, the pipeline system should be safely constructed as robust as possible during the installation process, hydrotest, and operation. In subsea pipeline design, free span (free span) is one of the most important part that must be considered. Failure of structures such as cracks may occur because the pipe is unable to withstand the working load of free spaces underneath the surface of the pipe due to uneven seabed. The emergence of cracks on the structure of pipe can lead to fatal leaks, either in the form of a significant decrement of the oil and gas production or impacts on the environment and human activities near the pipeline. Due to the expensive cost of pipeline repair or replacement works, the subsea pipeline design must be carried out through safe and efficient procedure which referenced to international design standards. Required nominal wall thickness is designed based on DNV OS-F101 to withstand all loads during construction, system pressure tests, and operation. Concrete weight coating thickness is calculated based on the DNV RP-F109 which fulfill the vertical and lateral on-bottom stability analysis criterion. A preliminary installation design then conducted using finite element-based software to ensure the pipeline fulfill DNV OS F101 and industrial installation analysis criterion. The free span analysis which based on DNV RP-F105 obtains maximum allowable free span length, so that the pipeline fatigue life can be predicted using software based on DNV RP-F105 and DNV RP-C203. <p align="justify"> <br />
