Subsea7 announced on Wednesday (05) that the heavy construction/flex-lay vessel Seven Arctic will be equipped with a new energy-saving system, after it closed a deal in June to expand the floating production of offshore green hydrogen.
The new energy saving and storage system will hybridize the vessel, which currently has a total installed power of 27 MW and a DP3 classification, and is suitable for worldwide operations in depths of up to 3,000 meters.
At the heart of the new energy storage system is a containerized battery room with a maximum power of 3,750 kW and 1,250 kWh of energy. The system also includes a connection for onshore power.

Based on the vessel’s operating profile, a reduction of 5,000 tons of CO 2 emissions is estimated.
The contract for the supply and installation of the Energy Storage System was awarded to Bakker Sliedrecht, an electrical integrator specialized in Dynamic Positioning (DP) vessels.
Stuart Smith, Vice President of Asset Development at Subsea7, said: “We are very pleased to continue our relationship with Bakker on this contract that will hybridize the Seven Arctic. This represents an important milestone in our sustainability program to reduce our C0 2. emissions.”
Bas Oskam, Sales Director at Bakker Sliedrecht, added: “The energy storage system can work with any type of battery or storage. The control system is designed with maximum autonomy in mind, allowing integration with different energy and vessel management systems already on board. This makes the system very suitable for application on existing vessels.”
