标准范围

ISO 19901-5:2003规定了在海洋环境结构物的工程和施工期间，通过质量管理控制重量和重心（CoG）的要求。本规定适用于包括所有类型和材料结构的海上项目。ISO 19901-5:2003区分了因重量和/或CoG敏感性而优先考虑重量和CoG的项目，以及重量和CoG影响不大的项目。这种区别是通过引入三种不同的结构类别（A类、B类和C类）实现的。根据必要的控制程度，ISO 19901的不同条款将适用；第4条提供了分配其中一个类别的指南。ISO 19901-5:2003规定了重量和重心报告的质量要求，规定了重量报告的要求，为所有类别的总体项目状态报告或管理报告提供了基础，规定了海上安装的重量和负载预算要求，规定了主要组件称重的方法和要求，以及重量和重心的确定，规定了供应商重量信息的要求，包括海上安装设备和散装材料的称重。可将其用作规划和展示承包商重量报告系统的基础；作为评估承包商重量报告系统的基础；作为完善结构分析/模型的手段；作为订购客户和承包商之间的合同参考；作为成本计算的基础。

ISO 19901-5:2003 specifies requirements for controlling the weight and centre of gravity (CoG) by means of mass management during the engineering and construction of structures for the offshore environment. The provisions are applicable to offshore projects that include structures of all types and materials.ISO 19901-5:2003 differentiates between projects where considerations with regard to weight and CoG have a high priority as a result of weight and/or CoG sensitivity, and projects where weight and CoG are of little consequence. This differentiation has been made by the introduction of three different classes of structure (Class A, Class B and Class C). Depending on the degree of control necessary, different clauses of ISO 19901 will apply; clause 4 provides guidelines for assigning one of these classes.ISO 19901-5:2003 specifies quality requirements for reporting of weights and centres of gravity, specifies requirements for weight reporting, provides a basis for overall project status reports or management reports for all classes, specifies requirements for weight and load budgets for offshore installations, specifies the methods and requirements for the weighing of major assemblies and the determination of weight and centre of gravity, specifies requirements for weight information from suppliers, including weighing of equipment and bulk materials for offshore installations.It may be used as a basis for planning and presentation of the contractor's weight-reporting system; as a basis for evaluation of the contractor's weight-reporting system; as a means of refining the structural analysis/model; as a contract reference between the ordering client and the contractor; and as a basis for costing.
