ZPMC completed the loading and marine delivery of five steel box girder segments for the Xiamen–Kinmen Bridge’s Xiamen section, helping keep the project on a faster construction schedule.

The work followed a factory-prefabrication and offshore transport model. The girders were produced in a smart factory to millimeter-level precision, then shipped to the bridge site for installation. By shifting key fabrication work off-site, the project combined controlled manufacturing with marine transport for the next stage of assembly.

During the first shipment, the team had to manage changing vessel stress together with tidal effects. To improve the operation, it adjusted the loading plan and used digital simulation to study force distribution during roll-on work. That change improved performance on the second vessel, cutting loading time from 6 hours to about 2 hours.

According to ZPMC, the operation reflected close coordination by the shipping team and careful control across a complex heavy marine transport task.
