FEASIBILITY STUDY FOR POST-TRENCHING OF OCTOPUS LNG PLANT GAS PIPELINE (CHILE)
Underwater pipelines
- Start Date / End Date: 2013
- Place: CHILE
- Scope: Fleasibility study
- Description:
A study to analyse the feasibility of installing a gas pipeline using post-trenching techniques.
The pipe is 20” (508 mm) carbon steel with a thickness of 10.3 mm
Specifically, the following tasks were completed:
. An analysis of the existing geotechnical aspects
. An analysis of existing tsunami studies, analysing their impact on the design
. The calculation of the concrete cover to ensure the stability of the ensemble in the event of liquefaction
. A description of the sinking system
. A description of the most appropriate post-trenching system.
. A study of subcontractor companies to analyse the feasibility of the system and the possibility of execution in the area.
