Study consisting of analysing the feasibility of installing the pipeline using post-trenching techniques. The pipeline is 20” (508 mm) carbon steel with a wall thickness of 10.3 mm. Specifically, the following tasks are carried out: . Analysis of existing geotechnical data . Analysis of existing tsunami studies, assessing their impact on the design . Calculation of the concrete coating to ensure overall stability in the event of liquefaction . Alternatives for the seabed positioning system (bottom towing, controlled flooding for anchoring, etc.) . Description of the most suitable post-trenching system. . Study of subcontractor companies to assess the feasibility of the system and the possibility of execution in the area.
