Port Machinery — Case Study
ZPMC (Nantong) Transmission Machinery Co., Ltd.
A central state-owned subsidiary of CCCC and a national-level specialised and innovative “Little Giant” and high-tech enterprise, the company focuses on high-end heavy-duty transmission equipment serving shield tunnelling/TBM, port machinery, offshore engineering, wind power and other sectors.
Pain Points
Coarse planning and difficult coordination
Workshop plans rely heavily on experience and manual spreadsheets. They are coarse and change frequently, while design data and material arrivals often trigger stoppages, material shortages or resource conflicts.
Too many steel plate specifications, excessive plate turning and high line-side inventory
Pre-nesting causes the number of steel plate specifications and plate-turning operations to balloon. Plate kitting still has room to improve, remnant reuse lacks data support, and high WIP inventories of parts and blocks tie up substantial capital and floor space.
People-dependent operations and poor process coordination
Outsourced labour leaves information fragmented across cutting, machining, assembly, welding and other stations. Operators depend on paper drawings and verbal communication, making real-time tasks, process parameters and exception feedback hard to obtain and weakening coordination between processes.
Black-box production data and delayed decisions
Equipment status, energy use, quality and progress are reported manually, making data late and unreliable. Management cannot see actual workshop capacity or bottlenecks in real time.
Severe departmental silos
Design, manufacturing, material distribution and planning teams exchange information through email or meetings. Changes are communicated late and coordination costs remain high.
Solution
This project delivered a digital workshop management platform for Waigaoqiao Shipbuilding’s hull-structure production workshop.
Eight integrated modules create closed-loop management from planning to execution and digitalise workshop plans, materials, equipment, personnel, energy and quality. The result is three fundamental shifts — from experience-based to data-driven management, from departmental silos to workstation collaboration, and from manual reporting to automatic data flow — laying a strong foundation for efficient, flexible and green production of high-value ships.
Solution Value
A fundamental transformation of the production organisation model
Precise workshop planning
Production tasks delivered directly to each workstation
Higher workshop automation
Parameters and programs sent directly to equipment
