Proposed on Bottom Stability Design Procedure for Sub Sea Pipelines Conswerjng Pipeline Oscillations

Abstract

This paper describes a proposed procedure to calculate the stability, against laten1 movement, of submarine pipelines resting on the seabed and exposed to wave or combined wave and current loadings. The procedure provides an estimate of the expected pipe embedment created by wave induced oscillatory pipe motions. Based on this expected pipe embedment into the soil, realistic hydrodynamic and soil force formnlatio~s''~ are used to check pipe stability for loadings expected during the design event. 2-54 2 4 4 &I tU &c i-X d I &&I
