SOIL RESISTANCE AGAINST PIPELINES IN JETTED TRENCHES
Pipelines and flow lines transporting high temperature oil and gas will be subject to high axial forces and may experience buckling. In areas where the pipeline requires burial for protection against impact from crossing objects, the backfilled soil will have to provide the lateral and uplift resistance required to prevent buckling. In offshore and near shore sandy soils, jetting is a preferred method for burial of pipelines. Jetting will bring the sand in suspension and the resedimented backfilled material will be very loose. Experience shows that upheaval buckling often occurred. The cost connected to production loss and repair can be considerable. Improved prediction methods and techniques to increase the upheaval resistance are discussed.
