The influence on the impact forces and mooring line forces of different water le els, different loaded drafts and different angles between wa e and current under fhe action of the single current and single wa e and undel that of the combined wa e and current are studied. The setting of the mooring lines and fender of the project is also analyzed. The results presented are of reference alue to the project.
