石油和天然气工业海上结构物的特殊要求第5部分:重量管理

[中文适用范围]： 本文件规定了在所有生命周期阶段通过质量管理来管理和控制海上设施的重量和重心（CoG）的要求，包括：概念设计、前端工程设计 (FEED)、详细工程、施工和运营。 这些可以是新设施（绿地）或对现有设施的改造（棕地）。 在整个运营、退役和拆除过程中，重量管理是必要的，以促进结构完整性管理 (SIM)。 本文件的规定适用于所有类型的固定和浮动设施。 体重管理仅包括具有静态质量的物品。 雪和冰荷载被排除在外，因为它们不被视为设施的一部分。 ISO 19904-1、ISO 19901-6 和 ISO 19901-7 中讨论了动态载荷。 本文件规定： a) 管理和控制组件和整个设施的重量和 CoG 的要求； b) 管理重量和重心接口的要求； c) 重量和 CoG 估计和报告的标准化术语； d) 确定不超过（NTE）权重和预算权重的要求； e) 对标记设备、组件、模块和设施的称重和重量和重心（CoG）确定的要求；本文件可用于： f) 作为成本计算、调度或确定合适的施工方法或位置以及安装策略的基础； g) 作为规划、评估和准备体重管理计划和报告系统的基础； h) 作为合同参考； i) 作为改进结构分析或模型的手段。 [外文原描述]： This document specifies requirements for managing and controlling the weight and centre of gravity (CoG) of offshore facilities by means of mass management during all lifecycle phases including; conceptual design, front end engineering design (FEED), detail engineering, construction and operations. These can be new facilities (greenfield) or modifications to existing facilities (brownfield). Weight management is necessary throughout operations, decommissioning and removal to facilitate structural integrity management (SIM). The provisions of this document are applicable to fixed and floating facilities of all types. Weight management only includes items with static mass. Snow and ice loads are excluded as they are not considered to be part of the facility. Dynamic loads are addressed in ISO 19904-1, ISO 19901-6 and ISO 19901-7. This document specifies: a) requirements for managing and controlling weights and CoGs of assemblies and entire facilities; b) requirements for managing weight and CoG interfaces; c) standardized terminology for weight and CoG estimating and reporting; d) requirements for determining not-to-exceed (NTE) weights and budget weights; e) requirements for weighing and determination of weight and centre of gravity (CoG) of tagged equipment, assemblies, modules and facilities; This document can be used: f) as a basis for costing, scheduling or determining suitable construction method(s) or location(s) and installation strategy; g) as a basis for planning, evaluating and preparing a weight management plan and reporting system; h) as a contract reference; i) as a means of refining the structural analysis or model.
