NES, specialising in sustainable energy design and smart control systems for vessels, will deliver a containerised energy storage system that includes a “Quest” battery charger, a 1 MW battery package, and a control system. The system is capable of operating in peak shaving, spinning reserve and harbour mode.

“Spinning reserve provides extra generating capacity that allows fewer generators to be used while maintaining the vessel's DP class. This results in significant savings on operational costs and helps to reduce emissions,” says Egil Bremnes, sales manager at NES.

Rem Offshore will install the energy storage system and associated equipment on board the Rem Inspector CSV. This vessel is 110 metres long, 22 metres wide, has a deck space of 1,000 square metres, and is equipped with a 150-tonnes crane.

“We have recently ordered our first newbuild net-zero emission vessel which shows that sustainability and commercial priorities go hand-in-hand at Rem Offshore. Upgrading our current fleet is another key component of this strategy. NES has a strong track record of delivering energy storage systems to offshore vessels, which is why we have chosen them as a cooperation partner for the Rem Inspector,” says Lars Conradi Andersen, CEO of Rem Offshore.   

NES will deliver the equipment during the first quarter of 2025 and manage the project from its headquarters in Bergen, Norway.

“Reducing energy consumption on offshore vessels is achieved through several measures, including integrating battery storage, energy management systems, and optimised propulsion. These efforts lead to both cost savings and lower emissions. Rem Offshore is committed to increasing fuel efficiency and providing customers with competitive, environmentally friendly vessels. We are proud to contribute to this forward-thinking approach,” says Siv Remøy-Vangen, managing director of Norwegian Electric Systems.

NES is a subsidiary of HAV Group ASA, which is listed on Euronext Growth Oslo. NES has operations in Bergen (HQ), Egersund and Ålesund in Norway, and Istanbul, Turkey.
