Project Management Model and Quality Control Strategy for Cruise Ship Interior Fit-out Projects

Abstract

As China's first domestically built large cruise ship, Adora Magic City, enters batch operation, cruise interior outfitting engineering—accounting for over 60% of total construction workload—has become the core bottleneck. Distinct from traditional ship outfitting and land hotel decoration, cruise interiors involve over 20 million components, multiple professional fields, and stringent international safety, classification, and health standards. Traditional decentralized management cannot meet these complex demands. This study breaks beyond single process-schedule frameworks to systematically construct a comprehensive management system covering multi-stakeholder coordination, full-process modular prefabrication, whole-chain quality traceability, and dynamic risk early warning. Drawing on verified data from two self-built Chinese large cruise ships, it analyzes international mainstream management evolution, identifies core pain points of multi-process interference in early domestic construction, and proposes a targeted total quality management system integrating digital twin platforms, standardized process specifications, and full-lifecycle performance verification. Results demonstrate that this optimized mode reduced interior rework rates from 12.7% to below 3.2%, shortened total outfitting cycles by over seven months, and achieved a 98.7% one-time qualification rate for modular cabin installation. These findings provide theoretical support and practical reference for China's subsequent batch cruise construction, enabling improved management, cost control, quality assurance, and narrowing the gap with world-leading cruise shipyards in interior outfitting engineering management.
