ABB has secured an order with Norwegian shipyard Ulstein Verft to supply a hybrid power and propulsion system for a forthcoming cable-laying vessel (CLV) of energy transition company Nexans.
On delivery in 2026, the vessel will join Nexans Skagerrak and sister ship Nexans Aurora – also equipped with ABB technology – as the third and most advanced CLV in the Nexans fleet.
An integrated system comprising main power generation and distribution, energy storage and electric propulsion is expected to enable the new CLV to execute its cable-laying, -recovery and -repair tasks in a safe and efficient manner. 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.
The onboard energy storage system (ESS) is expected to reduce engine running hours to keep wear and tear to a minimum. In addition, it will provide spinning reserve and peak-shaving capabilities, acting as a backup power source in the event 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 Rune Braastad, global business line manager of marine systems at ABB Marine & Ports. “Nexans appreciates the benefits that 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 cybersecurity configuration for the RDS. By providing precise and timely fault detection and continuously monitoring equipment health status, the RDS improves system performance and minimizes the need for on-site service. According to ABB, this will result in significant reductions in downtime and maintenance costs.
