The vessel will join Nexans Skagerrak and sister ship Nexans Aurora as the company’s third and most advanced CLV after delivery in 2026,

Engineering firm ABB will provide an integrated system comprising main power generation and distribution, energy storage, and electric propulsion, which will allow the new CLV to execute its cable-laying, -recovery, and -repair tasks safely and efficiently.

With a closed-ring configuration providing high fault tolerance and optimal engine use in dynamic-positioning (DP) operations, the system will minimize the risk of power loss for enhanced safety and reliability while maximizing operational flexibility and fuel efficiency.

An onboard energy storage system (ESS) will reduce engine running hours to keep engine wear and tear to a minimum. The ESS will also provide spinning reserve and peak-shaving capabilities, acting as a backup power source in case of engine failure and supporting the vessel’s more energy-intensive operations.

“Following the success of Nexans Aurora, ABB is proud to be involved in this project to deliver the new sister ship,” said ABB Marine & Ports global business line manager marine systems, Rune Braastad.

“Nexans appreciates the benefits our closed-ring system, ESS, and RDS provide to support safe, efficient, and reliable cable-laying operations. We look forward to strengthening our relationship with both Nexans and Ulstein Verft.”

Alongside main system components – generator, switchboards, transformers, frequency converters, motors, DC switchboard for batteries, and ESS – ABB’s scope of supply includes the remote diagnostic system (RDS) for propulsion, thruster inverters, and rectifiers as well as the cyber security configuration for the RDS. ABB said by providing precise fault detection and continuously monitoring equipment health status, the RDS improves system performance and minimises the need for onsite service.
