Battery implementation in offshore oil and gas vessels has been in the market for almost a decade. The battery provides system redundancy and safety and, at the same time, improves fuel efficiency and supports carbon reduction efforts in the oil and gas industry.
In Offshore Wind Service Operation Vessels, use of battery technology is still relatively new and has been implemented only within the last three to five years.
The battery design and actual battery operation in both industries will be compared in this article in terms of battery utilization to reduce emissions and to provide additional safety and system redundancy.
The article presents data analysis of actual battery operations from both segments, Offshore Wind Service Operation Vessels and oil and gas vessels, with data collected from a Corvus visualization tool that compiles operational data from a worldwide base of installed marine battery systems. The comparisons will cover the following topics:
1) electrical design and its operation (open bus versus closed bus); 2) battery capacity; battery charge and discharge powers (kW), and respective current (Amps); and energy (kWh); 3) Emission reduction and fuel efficiency; 4) lastly, the paper will review the battery notation and approval from the class societies that dictate safety and redundancy standards for both applications.
Several graphs will provide visual observations of the battery operation in both segments. Based on the data visualization, the analysis will be drawn. The study will highlight the system differences, operator familiarity with battery operation, system adoption, and daily operational usage to promote fuel efficiency and emission reduction.
The paper will conclude with the importance of matching the battery design profile to the operational load profile, or actual planned system use. which can drive higher fuel efficiency and emission reduction.
The battery as energy storage plays an essential role in improving energy efficiency and supporting carbon reduction efforts. Battery-powered, all-electric operations produce zero emissions and consume zero fuel, enabling Hybrid systems that leverage battery power to significantly reduce emissions and fuel use.
There are specific lessons learned from battery implementation in the oil and gas industry that can be applied in the offshore wind industry to accelerate battery technology adoption. It is recommended that both industries – offshore wind and offshore oil and gas – exchange battery operational information to improve safety and redundancy and to optimize fuel efficiency, battery performance, and operational cost savings.
