ABB has secured an order with Norwegian shipyard Ulstein Verft to supply an advanced power and propulsion system for a forthcoming cable-laying vessel (CLV) being built for 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 will allow the new CLV to execute its cable-laying, -recovery, and -repair tasks in a safe and efficient manner. With a closed-ring configuration providing fault tolerance and optimal engine use in DP operations, the system is intended to minimise the risk of power loss for enhanced safety and reliability while maximising operational flexibility and fuel efficiency.
The onboard energy storage system (ESS) will reduce engine running hours to keep engine wear and tear to a minimum. In addition, the ESS will provide spinning reserve and peak-shaving capabilities, acting as a back-up power source in case of engine failure and supporting the vessel’s more energy-intensive operations.
Rune Braastad, Global Business Line Manager, Marine Systems, ABB Marine & Ports said: “Following the success of Nexans Aurora, ABB is proud to be involved in this project to deliver the new sister ship. 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 cyber security configuration for the RDS. By providing fault detection and continuously monitoring equipment health status, the RDS should improve system performance and minimise the need for on-site service, saving downtime and maintenance costs.
