However, achieving precise control of overhead cranes remains a challenge, primarily due to undesired oscillations of the heavy loads, especially under varying rope lengths. Traditional feedforward control methods are effective only under constant rope length, limiting performance during simultaneous hoist and trolley operation. Feedback-based approaches can compensate for changing conditions but often rely on complex sensor integration and continuous velocity adjustments, which may increase system complexity and operation cycle time. To address these practical challenges, this study proposes a reinforcement learning (RL)-based feedforward control approach that integrates a model-based offline ensemble with online selection to maintain high performance across diverse conditions. In a simulation crane model environment, the RL agent is trained to generate trajectories that minimize both residual sway angle and operating time. The proposed strategy pre-identifies optimal models for specific operating domains, allowing for efficient execution by selecting a single optimal model during the online stage. Although this approach involves a trade-off requiring substantial offline training to construct the model map, it reduces online complexity suitable for industrial PLCs. This approach minimizes the real-time computational burden compared to conventional ensemble methods, generating near-optimal trajectories under varying rope lengths without relying on explicit sensor feedback. We validated this method through simulations and experimental tests, demonstrating a 38% reduction in operation time and effective sway suppression with residual angles under 0.3°, which demonstrates its feasibility for practical industrial applicability.</div></div>","PeriodicalId":14160,"journal":{"name":"International Journal of Naval Architecture and Ocean Engineering","volume":"18 ","pages":"Article 100763"},"PeriodicalIF":3.9,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147749128","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, P&IDs (Piping and Instrumentation Diagrams) were converted into system graphs consisting of equipment nodes and connection edges. System similarity was computed by embedding graphs with graph2vec and ranking candidates by cosine similarity to retrieve past systems structurally closest to the target system. Second, the retrieved system's historical 3D routes were normalized by principal ship dimensions and used to construct a routing space. To reflect both proximity and segment orientation, DBSCAN (Density-Based Spatial Clustering of Applications with Noise) was extended with an angular-distance term between segment direction vectors, and the resulting clusters were merged and scaled to the target ship geometry. A past pipe centerline was then transferred into the routing space and adjusted by solving a constrained optimization with GA (Genetic Algorithm), where bend nodes are treated as design variables and their motion is restricted to preserve the original route shape. Feasibility was evaluated using a SphereCast-based collision penalty against hull and obstacle colliders. By enabling retrieval-conditioned reuse of proven route patterns and automated collision-aware adjustment within a learned routing space, the proposed method supports rapid generation of feasible initial piping layouts for new ship projects while reducing manual trial-and-error in early-stage routing.</div></div>","PeriodicalId":14160,"journal":{"name":"International Journal of Naval Architecture and Ocean Engineering","volume":"18 ","pages":"Article 100755"},"PeriodicalIF":3.9,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147396763","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
