The Kang Sheng Kou (KSK) semi-submersible heavy lift vessel, provided by Greece’s Asso.subsea, has arrived in New York to support the $6 billion Champlain Hudson Power Express (CHPE) project. This project aims to link Canada and New York City with a high-voltage direct current (HVDC) cable system, enhancing the city's renewable energy infrastructure.

The KSK vessel, responsible for transporting the Atalanti cable-laying vessel from Karlskrona, Sweden, will now assist in laying and burying a 400 kV DC submarine cable along the Hudson River. This phase of the project, managed by NKT, involves laying two bundled HVDC cables over a span of more than 85 miles (140 km), navigating shallow waters, strong currents, and multiple utility crossings.

Scheduled to begin in Q2 2024 and complete by Q4 2025, the cable-laying operations are crucial for the CHPE project, which will transmit renewable energy from Hydro-Québec in Canada to New York City. The full project will span approximately 339 miles (545 kilometers) and deliver up to 1.25 GW of electricity, enough to power over 1 million homes in NYC.

DeepOcean is handling the subsea mattress installation along the Hudson River, while Hitachi Energy is supplying the HVDC converter station technology. Kiewit Corporation is the lead contractor for the site. The CHPE project, expected to reduce CO2 emissions by 3.9 million metric tons annually, aligns with New York’s goal of 70% renewable electricity by 2030 under the Climate Leadership and Community Protection Act (CLCPA).

Once completed, the project will significantly advance New York’s clean energy transition and support the city’s climate goals.
