1.1 意图 — 本指南涵盖了帮助船东在维护、维修、改装、采购谈判或报废活动期间规划成本或安排复杂情况的信息。在系统或组件的修改、维护或处置过程中，移除和处置某些受到干扰的材料可能成本高昂，或会中断工作进度。 1.2 目标: 1.2.1本指南将描述在维护或报废活动期间船舶上可能受到干扰的材料，这些材料可能会导致昂贵或耗时的移除或处置行动。 1.2.2本指南将提供一种系统方法来识别和记录相关材料的位置，以供立即规划和未来参考。 1.2.3本指南将简要讨论与本指南中所述材料的搬运和储存相关的问题。 1.3 超出范围的考虑: 1.3.1本指南不涉及作为货物运输的材料或储存在预包装容器中的材料。 1.3.2本指南不旨在解决与船舶日常运行有关的废物，如污水、固体废物、焚烧炉灰（或固体废物处理产生的其他残余产物）和留在隔离压载舱中的残余污泥。 1.3.3本指南未提供可用于表征所讨论材料的试验方法的综合指数。引用或描述的试验方法应视为示例。 1.3.4本指南无意直接解决所述任何材料的监管问题。 1.3.5本指南旨在解决补救问题。 ====意义和用途====== 适用性 — 本指南旨在描述规划审计，该审计将提高船东预测成本和进度影响的能力，并帮助船东识别与潜在危险船上材料的移除、处理和处置相关的环境、健康和安全问题。 使用 — 可以进行审计，以帮助规划各种事件，包括维护、维修、修改、采购或报废。为了最大限度地提高效率，应根据船东的具体需求进行审计，并在规划过程中确定目标材料。 小心 — 在美国国内和国外，本指南中讨论的材料的移除和处置的法律限制可能因港口而异。这种变化的原因包括港口控制的分散性、州和地方环境法规，以及当地垃圾填埋或处理设施的可用性。本指南的用户应咨询地方当局，以获取有关具体法律要求的信息。

1.1 Purpose — This guide covers information for assisting shipowners in planning for costs or scheduling complications during maintenance, repair, modifications, purchase negotiations, or scrapping activities. Removal and disposal of certain materials disturbed during modification, maintenance, or disposal of systems or components may be costly or interrupt the work schedule. 1.2 Objectives: 1.2.1 This guide will describe materials that may be disturbed on ships during maintenance or scrapping activities, which may result in costly or time-consuming removal or disposal actions. 1.2.2 This guide will provide a systematic method to identify and record the locations of materials of concern for immediate planning and future reference. 1.2.3 This guide will include a brief discussion of issues related to the handling and storage of materials described in this guide. 1.3 Considerations Beyond Scope: 1.3.1 This guide is not intended to address materials carried as cargo or material stored onboard in prepackaged containers. 1.3.2 This guide is not intended to address waste products related to the ongoing, day-to-day operation of a ship, such as sewage, solid waste, incinerator ash (or other residual products resulting from solid waste treatment), and residual sludge left in segregated ballast tanks. 1.3.3 This guide does not provide a comprehensive index of test methods available for characterizing the materials discussed. Test methods referenced or described should be considered as examples. 1.3.4 This guide is not intended to address directly regulatory issues for any of the materials described. 1.3.5 This guide is not intended to address remediation concerns. ====== Significance And Use ====== Applicability — This guide is intended to describe a planning audit that will improve the shipowner's ability to forecast costs and schedule impacts and aid the shipowner in identifying environmental, health, and safety concerns associated with the removal, handling, and disposal of potentially hazardous shipboard materials. Use — Audits may be performed to aid in planning for a variety of events, including maintenance, repair, modification, purchase, or scrapping. To maximize efficiency, audits should be tailored to meet the specific needs of the shipowner, with target materials identified during the planning process. Caution — Legal restrictions on the removal and disposal of materials discussed in this guide may vary significantly from port to port, both within the United States and abroad. Reasons for this variation include the decentralized nature of port control, state, and local environmental regulations, and the local availability of landfill or treatment facilities. Users of this guide should consult local authorities to obtain information on specific legal requirements.
