In a significant step toward decarbonizing the maritime sector, Norway’s Rem Offshore has partnered with Norwegian Electric Systems (NES) to retrofit one of its construction support vessels (CSV), the Rem Inspector, with a cutting-edge battery energy storage system (ESS). This development showcases the rising trend of integrating clean technologies into existing fleets, demonstrating how energy-efficient solutions are powering the future of greener subsea operations.
Powering Efficiency and Sustainability with Battery Storage
Rem Offshore’s initiative reflects a growing awareness within the maritime industry to enhance operational efficiency while curbing carbon emissions. By outfitting the Rem Inspector with NES’ advanced battery storage technology, the ship will significantly reduce its reliance on diesel generators. This innovative system, which includes a 1 MW battery package and a ‘Quest’ battery charger, enables the vessel to function in modes such as peak shaving, spinning reserve, and harbor operation.
NES’ Sales Manager, Egil Bremnes, highlights the importance of this transformation, stating, “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.”
These enhancements align with Rem Offshore’s broader sustainability goals, which are reinforced by their recent deal with energy giant Equinor to perform inspection, maintenance, and repair (IMR) operations on the Norwegian Continental Shelf. With the Rem Inspector slated for offshore deployment in April 2025, the incorporation of battery energy storage systems will not only ensure a reduction in fuel consumption but also extend operational reliability, thereby maintaining the vessel’s competitive edge.
Sustainability at the Core of Retrofitting
Rem Offshore’s focus on sustainable innovation is further underscored by their strategic investment in ESS retrofits for their fleet. As Lars Conradi Andersen, CEO of Rem Offshore, explains, “Upgrading our current fleet is a 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.”
By upgrading existing vessels alongside building new net-zero emission ships, Rem Offshore is setting a precedent in the offshore industry for sustainability and efficiency. The introduction of hybrid systems that combine batteries with traditional diesel-powered generators is expected to drive significant operational cost savings and emissions reductions, positioning the company as a leader in sustainable maritime solutions.
