Abstract: Describe the working principle of the marine stern roll and study the form of working loads on
it and the method for structural strength calculation with Finite Element Method (FEM). With the
calculation of some traditional one for example, an analysis of their stress distribution characteristics and
the limitations of carrying capacity is made. Then a concept of the large stern roll which can effectively
increase their loads is proposed. And the structure strength reliability of an improved stern roll and its
variety of application forms through a calculation is verified with examples.
Key words: marine stern roll; ocean structure; strength calculation; finite element method
