This talk will consist of two parts; the first part aims to highlight the importance of understanding soil classification and it’s limitations on pipe-soil interaction design. The second part presents a case study on how a live gas pipeline was lowered by 6 m for a length of about 350 m, which is the world’s first such lowering. The second part of the talk will present a project case study of a live gas pipeline lowering. A live gas pipeline was crossing a shipping channel and was buried at 3 m below seabed.
