China’s ZTT Submarine Cable & System Begins Construction of Advanced Cable Laying Vessel
China’s ZTT Submarine Cable & System has initiated the construction of an innovative cable laying vessel (CLV) designed to cater to offshore wind, island interconnections, and regional grid expansion projects in the Asia Pacific region (APAC).
The CLV will measure 139.8 meters in length, with a 38-meter beam, and will be equipped with diesel generators utilizing electric drive and DP2 dynamic positioning systems. Additionally, it will feature a helicopter platform, large coaxial turntables, and dual-launch channels.
Capable of handling a 16,000-ton cable capacity and installing over 1,000 kilometers of cable annually, the vessel is set to navigate complex marine environments and facilitate simultaneous dual-cable laying, deepwater single-hook operations, and cross-border project executions.
“This milestone underscores our dedication to partnering with global installation specialists. By working in tandem, we enhance regional project delivery, advance shared energy transition goals, and drive sustainable progress in offshore development worldwide,” ZTT expressed.
Recent news from ZTT Submarine Cable & System revealed the company securing a 500 kV submarine cable contract for Shenzhen Energy’s 500 MW Honghai Bay VI offshore wind project in China.
The article was updated at 11 a.m. on August 6 to clarify that the vessel will be equipped with diesel generators with electric drive, not pure-electric drive as previously stated.
