Finnish technology group Wärtsilä announced the installation of energy storage systems onboard the offshore construction vessel North Sea Giant which the group says could deliver impressive fuel savings of up to 50 percent.
Wärtsilä says the installation of three energy storage systems features, for the first time ever, energy and load sharing capability. The system combines a diesel-electric configuration with batteries.
The installation was carried out in February 2018 onboard the North Sea Shipping-owned ‘North Sea Giant’, one of the world’s largest and most advanced subsea construction vessels.
In a second phase of the project, Wärtsilä says it commissioned an electronic bus link, a newly developed module that allows the ship to share load and energy optimally between the three energy storage systems.
The company says the technology is expected to generate additional operating cost savings, and a total reduction in annual fuel consumption of two million liters, leading to an annual reduction in exhaust emissions of 5.5 million kg of CO2, 30 tons of nitrogen oxides (NOx), and 1200 kg of sulphur oxides (SOx).
