Specific Design Requirements for Access Equipment



This chapter describes the specific requirements of the 1966 Load Line Convention where it affects minimum material thicknesses and loadings, as well as giving an outline of the design procedure used for hatch covers and Ro-Ro vessel access equipment. Wheeled vehicles and their axle loadings are described, including the highway regulations for vehicle sizes in major maritime countries. Sealing arrangements are discussed, as well as the materials used in the construction of access equipment. A miscellaneous section at the end of the Chapter describes fire regulations, actuating mechanism power requirements and problems caused by icing.
