As the oil and gas exploration moves gradually in the area of deep sea, the umbilical becomes more complex and heavier, with its top tension increased. The lazy-wave configuration umbilicals are usually introduced to reduce the top tension, but it also induces a greater chance to clash with other pipelines. So interference analysis for deepwater lazy-wave umbilical becomes indispensable. A parametric study of deepwater lazy-wave umbilical under environmental loads with various parameters, such as azimuth heading, drag coefficient, outer diameter of buoyancy modules, etc was performed and the results show that a suitable layout configuration of the umbilical is strongly dependent on these parameters. Then the interference of two umbilicals in Spar platform and that between the umbilical and the tendon in TLP (Tension Leg Platform) were studied. The analysis conclusions can help designers to understand the dynamic behavior of deepwater lazy-wave umbilical.
