With the localization of flexible pipes, more and more oil fields use the flexible pipe as conveying flowline. End fitting whose function is to connect the pipe sections is a rigid structure, while the pipe body is flexible, there is a stiffness mutation between them. When subjected to a large bending moment, the pipe body will be damaged, so it is necessary to set a bend stiffener between the pipe and the end fitting. To design a bend stiffener, an applicable material should be selected. We use polyurethane elastomer as the principal material for the bend stiffener. Besides, some steel interface structures are requisite. We mainly introduce a static bend stiffener design. It can protect the pipe during installation and overboarding.
