A simplified model is proposed to predict Heave Induced Lateral Motion (HILM) for Steel Catenary Risers (SCR), based on experimental measurements carried out at IFREMER Brest. Two campaigns were conducted to obtain data on the displacement of a SCR in the Touch-Down Zone (TDZ) induced by top motion. The first campaign was used to understand the response of the structure and develop the model. A second campaign was launched to obtain a wider range of data in terms of heave amplitude and frequency. This data were used to define the model parameters. The influence of heave lateral motion on riser damage was then assessed.
