Pain Points

Pain Points

01.

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.

02.

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.

03.

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.

04.

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.

05.

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.

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
