<p>is somewhat thinner than the average thickness of each of of the side walls (1, 1'). If the constructional height of the fender is H then the contact wall thickness is 0.20 to 0.30 H and the side wall thickness 0.25 to 0.35 H. The stiffness of the contact wall is interrupted by the longitudinal groove (5) which divides the contact wall into two equal flat regions. The width of the groove is between 0.15 and 0.25 H and its depth between 0.20 and 0.30 H. The base (7) of the grooved section can have a semi-circular cross section. This design of fender is intended to protect the relatively thin outer hull skin of a large ship.</p> |
