ZPMC has dispatched the jacket foundation for the Sanshan Island offshore converter station, a central component of China’s first offshore wind flexible HVDC transmission project linking offshore and onshore systems.

According to the company, the structure set national records for both size and weight. During the transport and loadout campaign, the project team kept close control of vessel draft, trim, list and ballast operations. It also coordinated the working window with tidal conditions and designed the mooring system to meet strict operational requirements.

The company said these measures enabled the roll-on/roll-off operation to be completed smoothly. The delivery supports the next phase of construction for the clean energy transmission link serving the Guangdong-Hong Kong-Macao Greater Bay Area.

The shipment marks a further step in the build-out of infrastructure tied to the offshore wind power project and its associated converter station.
