World’s largest cable-laying vessel to connect 1,700 miles of offshore wind farms
AI Article Summary

The family-owned Belgian marine construction company Jan De Nul has launched the world's largest cable-laying vessel, the Fleeming Jenkin, at the CMHI Haimen shipyard in China. With a 28,000-ton cable-carrying capacity, the vessel aims to support the installation of subsea cables for offshore wind farms and power grid connections. This advanced vessel is expected to help in Europe's transition to large-scale clean power transmission, starting with a mission under Dutch-German grid operator TenneT's 2GW Program. Additionally, Jan De Nul is planning to introduce a new subsea rock installation vessel, the George W. Goethals, to meet global demands for underwater infrastructure protection.

What This Means for Canadian Contractors

This project shows how advanced technology can reduce costs and ecological footprints, offering Canadian contractors insights for incorporating similar innovations in their operations. For Canadian builders, this means looking into large-scale maritime construction projects, which can lead to collaborations with global leaders like Jan De Nul. Additionally, this sets a benchmark for integrating low-emission technologies and renewable energy solutions into construction projects.
