The paper presents four different layouts of a subsea steel tube umbilical which is composed of six steel tubes, three electrical cables and one optical fiber cable. When the umbilical is loaded, there will be a relatively large stress and deformation when the cross-sectional layout is unreasonable. So the principles of the cross-sectional layout of the umbilical are studied considering the stress and deformation of components. The contact stress between components, stress and deformation of components are analyzed and compared based on finite element method. The preferable design of cross-sectional layout for this umbilical is present.
