Vard Electro has received a contract for an innovative hybrid battery power system from Canadian company Atlantic Towing, for a system to be retrofitted to the vessel 'Atlantic Shrike'.

Atlantic Towing believes this to be the first implementation of multiple mode battery technologies on a single vessel in the Canadian Offshore Oil and Gas Industry. Atlantic Towing has received funding for the project through Petroleum Research Newfoundland & Labrador (PRNL) as a component of the offshore research, development and demonstration program of Natural Resources Canada’s (NRCan) Emissions Reduction Fund (ERF). The funding will support upgrades to the PSV Atlantic Shrike and allows the integration of battery systems into the vessel’s existing diesel-electric propulsion plant.

Using its experience as a system integrator, Vard Electro will deliver a containerised energy storage system (ESS) for hybrid battery power. Supporting Atlantic Towing’s goal of reducing its carbon footprint, the SeaQ ESS will enable decreased fuel consumption and carbon emissions. The conversion will also reduce the vessel’s maintenance requirement without compromising operational performance.

“We share the ambitions of Atlantic Towing and are looking forward to implement the products and integrated solutions that will lead to a greener industry. The innovative design and extended battery size offer a range of benefits and will be a perfect fit for the operational profile of this vessel” said Peter Pilskog, VP Sales & Business Development, Vard Electro.

The main system components are all fitted into the self-contained deck house to ensure a fast vessel installation while keeping a high focus on quality. Control and monitoring of the hybrid system is handled by the energy management system (EMS) that communicates with the existing control systems onboard. The SeaQ ESS includes modes for peak shaving, spinning reserve and Zero emission transit. By using the batteries to absorb and dispense energy through load fluctuations and running the engines at optimal load, significant efficiency improvements in fuel consumption and emission reduction can be achieved.

The SeaQ ESS stores excess energy available in the vessel and uses it later to reduce fuel consumption and optimise the performance of the vessel. It facilitates operations with fewer engines online, and the engines can operate at an optimal load. Safety is increased due to the batteries' ability to supply immediate energy in critical situations.

The system can be used as a spinning reserve in DP operations, to enhance dynamic response, to perform peak shaving of loads, for strategic loading where the operating point of the gensets is optimized for battery only operations with zero-emission.
