Heavy construction and flex-lay vessel Seven Atlantic will get a new energy-saving system that will essentially make the vessel a hybrid vessel.
Bakker Sliedrecht, the Netherlands-based provider of electrical and automation solutions for the marine industry, will supply and fit a battery energy storage system as a ‘double first’, the company says - because it’s the first order it has received for this kind of system on this scale, and it believes the vessel is the first vessel of its kind to be equipped with one.
The system comprises two containerised power converters with 3,750kW of power each, plus battery storage of 1,500 kWh.
“The Energy Storage System is developed in close cooperation with Subsea7 to meet their ambition to make their fleet more sustainable,” said Andy Waterstreet, project director at Bakker Sliedrecht. “Before implementation on board, an extensive function and load test program in our workshop will be executed. This will contribute to a shorter duration for implementation and commissioning on board.”
“The Energy Storage System can work with any battery or storage type,” said Bas Oskam, sales director with Bakker Sliedrecht. ”The control system is designed with maximum autonomy in mind, allowing for integration with different existing power and vessel management systems on board. This makes the system very suitable to apply in existing vessels.”
Owned and operated by the firm Subsea7, as a cable-laying vessel Seven Atlantic has a depth capability of 3,000 metres.
Vice-president Asset Development with Subsea7 said the installation represented an important milestone in the company’s sustainability programme.
