Volstad Maritime has contracted Norwegian Electric Systems (NES) to deliver a battery package and associated control system for battery charging to the ‘Deep Cygnus’ subsea construction vessel.
NES, which specialises in sustainable energy design and smart control, will provide the equipment to the Deep Cygnus in connection with its forthcoming vessel upgrade to battery power notation before the vessel enters a new charter contract in early 2024.
During the past six months, Volstad Maritime has contracted NES to deliver similar battery packs and charging system to the Volantis, Grand Canyon II and Grand Canyon III offshore construction vessels. Deep Cygnus will be the fourth vessel where Volstad orders a battery system from NES.
Volstad Maritime project manager Trond Volstad said: “We are investing significantly in upgrading and future-proofing our fleet of offshore construction vessels. Reducing the offshore industry’s CO2 footprint is a shared responsibility that we take seriously. An added benefit is that our vessels become even more attractive to customers who also want to reduce emissions associated with their offshore operations. To achieve this, we rely on close cooperation with key suppliers such as NES, who we have an open and trust-based relationship with.”
The Deep Cygnus is a dynamically positioned multi-role subsea construction vessel incorporating a 150t active heave compensated subsea crane. The vessel is 122m long and has operated in the North Sea in recent years.
Egil Bremnes, sales manager NES added: “Upgrading the Deep Cygnus with a battery is similar to the upgrade we are doing onboard Volantis, where we placed the battery and charger under deck in custom-made rooms.”
As one of the first offshore owners to achieve the ISO 50001 accreditation for Energy Management Standard, Volstad Maritime continues the work towards a sustainable future at sea.
NES will utilise competence across its three Norwegian facilities – Bergen (HQ), Egersund and Ålesund – to design, assemble and test the battery package and control system, which will be delivered in the fourth quarter of 2023.
