中文摘要：	海洋平台作为海洋资源开发的核心基础设施，其结构设计变更管理的成效直接关系到项目的成本、进度与安全。A公司作为海洋工程领域的专业设计服务提供商，在业务拓展过程中，其现行的设计变更管理模式在流程规范性、跨部门协同、变更影响评估及对外沟通影响力等方面暴露出诸多问题，难以满足复杂项目的管理需求，对公司的市场竞争力和盈利能力构成了挑战。 本研究以A公司海洋平台结构设计变更为研究对象，旨在构建一套适用于设计方角色、系统高效的变更管理优化方案。研究首先通过文献梳理与案例分析，回顾了决策理论、风险管理、全生命周期管理、配置管理（CMII）及接口管理等相关理论；进而结合对2020-2024年间公司28个典型项目的变更台账分析及深度访谈法，深入剖析了A公司当前变更管理的现状、主要问题及其深层根源。研究识别出，流程制度不完善、沟通机制缺失、评估方法欠缺以及人员能力与意识不足是导致其管理效能低下的核心症结。 针对上述问题，本研究提出了一套完整的优化方案。首先，确立了以专业性、内部高效协同、全生命周期成本效益及沟通有效性为核心的优化原则。其次，创新性地设计并建立了一套标准化的“设计变更影响评估规范”，引入AHP层次分析法确定评估维度权重，并定制了符合海洋工程特征的FMEA评价准则，明确了评估内容、方法与跨职能团队职责。再次，对设计变更的内部处理与对外建议流程进行了全链路优化，其核心产出是高质量的《设计变更建议包》，旨在将技术评估转化为影响业主决策的关键依据。为验证方案有效性，选取两个典型项目进行回溯模拟验证，并对30份变更审批单进行曼-惠特尼U检验（P=0.000<0.05），证明优化方案具有统计显著性。最后，为确保方案落地，提出了涵盖组织架构（设立变更管理委员会CGC与办公室CMO）、管理信息系统、人员综合能力以及对外协同沟通机制的“四位一体”保障措施。 本研究旨在系统提升A公司作为设计方的内部变更管理效能与外部专业影响力，通过减少因内部低效和评估不准引发的额外成本，并通过高质量的建议输出增强话语权，从而为公司巩固市场竞争优势提供理论支持与实践指南，并为同类型海洋工程设计企业在权限受限情境下的变更管理实践提供了可复用的方法论框架与案例参考。
英文摘要：	As critical infrastructure for marine resource development, the effectiveness of structural design change management in offshore platforms directly impacts project cost, schedule, and safety. Company A, a specialized design service provider in the offshore engineering sector, has encountered significant challenges in its current design change management model during business expansion. Issues related to process standardization, cross-department collaboration, change impact assessment, and external communication have emerged, hindering its ability to meet the demands of complex projects and posing threats to the company's market competitiveness and profitability. This study focuses on optimizing the structural design change management process for Company A's offshore platforms, aiming to develop a systematic and efficient improvement strategy tailored to the role of a design service provider. The research begins with a review of relevant theories, including decision theory, risk management, life cycle management, configuration management (CMII), and interface management, through literature analysis and case studies. Furthermore, by examining change logs from 28 typical projects between 2020 and 2024 and conducting in-depth interviews, the study identifies the current state, key issues, and root causes of Company A's change management practices. The analysis reveals that inadequate processes, insufficient communication mechanisms, lack of robust assessment methods, and limited personnel competency and awareness are the core reasons for management inefficiencies. To address these issues, this study proposes a comprehensive optimization plan. First, it establishes core principles centered on professionalism, internal collaboration, lifecycle cost-effectiveness, and communication efficiency. Second, it innovatively designs and introduces a standardized "Design Change Impact Assessment Specification," incorporating the Analytic Hierarchy Process (AHP) to determine evaluation dimension weights, and customizes Failure Mode and Effects Analysis (FMEA) evaluation criteria tailored to offshore engineering characteristics, clarifying assessment content, methodologies, and responsibilities of cross-functional teams. Third, it optimizes the end-to-end internal processing and external recommendation processing for design changes, with a key output being high-quality "Design Change Proposal Packages" aimed at translating technical assessments into influential decision-making tools for clients. To validate the effectiveness of the proposed solution, retrospective simulation validation is conducted on two typical projects, and the Mann-Whitney U test (P=0.000<0.05) performed on 30 change orders demonstrates statistically significant improvement. Finally, to ensure implementation, a "four-pronged" safeguard mechanism is proposed, covering organizational structure (establishing a Change Governance Committee (CGC) and Change Management Office (CMO)), management information systems, comprehensive personnel training, and external collaboration mechanisms. This study aims to systematically enhance Company A's internal change management efficiency and external professional influence as a design service provider. By reducing additional costs caused by internal inefficiencies and inaccurate assessments, and strengthening its voice through high-quality recommendations, the research provides theoretical support and practical guidance for strengthening the company's market competitive advantage. It also offers a reusable methodological framework and case reference for similar offshore engineering design enterprises operating in contexts with limited authority.
