DYNAMIC NUMERICAL MODELS FOR SAND WAVES AND PIPELINE SELF-BURIAL

Carsten Staub, Romke Bijker

Abstract


Two independent numerical models for prediction of sand wave heights and migration rates and for calculation of pipeline/cable seabed interaction have been developed. Both models are fully dynamic and respond to detailed and comprehensive input describing environmental conditions, seabed and soil characteristics and pipe/cable data. The models are based on state-of-the-art knowledge and include theoretical developments, model tests, field data and advanced sediment transport formulations. The models have been validated and calibrated against field data of sand waves and buried pipelines.
