As the maritime industry faces growing pressure to reduce its environmental impact, optimizing onboard energy management is becoming an essential aspect of sustainable shipping.
Beyond the power required for propulsion, a significant amount of electrical power is needed to sustain the crew and various support systems, including cooling water pumps, ventilation fans, control systems, and navigation aids.
Additionally, many ships, particularly passenger ferries and cruise ships, have significant power demands for passenger comfort, including ventilation and air conditioning. These ships also often need to produce fresh water, another drain on energy generators onboard.
Specialized vessels have other unique energy requirements. For instance, cargo ships carrying refrigerated or frozen goods need substantial power for cooling systems to maintain cargo quality. Similarly, ships transporting certain types of crude oils, heavy fuel oils, or bitumen require heating to keep their cargo in the appropriate state. While some heat can be generated using steam from exhaust gases, additional steam boilers are often necessary to meet the demand, especially when the ship is in port.
Effective energy management, supported by automation, can significantly improve energy efficiency across these and other vessel types, thus contributing to a zero-emission future.
Reducing Energy Consumption through Optimal Operations
Significant opportunities exist to reduce energy consumption on board ships by adopting more conscious and optimized operational practices. Key measures include:
Avoidance of unnecessary energy consumption by minimizing the use of energy-intensive systems when not needed.
Avoidance of unnecessary energy consumption by minimizing the use of avoidance of parallel operation of electrical generators by ensuring that generators are not running in parallel unless necessary, thus reducing redundant energy usage.
Optimization of steam plant operations with efficient steam production and distribution management, particularly on tankers.
Optimization of fuel clarifiers and separators by ensuring these systems operate at peak efficiency.
Optimized HVAC operation with fine-tuning heating, ventilation, and air-conditioning systems to match actual requirements.
Regular cleaning of economizers and heat exchangers by maintaining these systems to ensure they operate optimally.
Detection and repair of leaks by promptly addressing leaks in steam and compressed-air systems to prevent energy wastage.
Implementing these measures often requires crew training, motivation investments, and systematic energy consumption monitoring and benchmarking. Moreover, upgrading automation and process control systems, such as automatic temperature, flow, and lighting, can save energy. While the potential savings depend on the vessel's baseline efficiency, a 10% reduction in auxiliary power consumption is realistic for many ships, corresponding to approximately 1-2% of total fuel consumption.
Role of Automation in Energy Efficiency
Role of Automation in Energy EfficiencyAutomation plays a critical role in enhancing energy efficiency on board ships. Advanced control systems have been developed to adjust various ship systems automatically to optimize energy usage. For example, an automatic temperature control system can ensure that heating and cooling are only provided when and where needed, thus reducing unnecessary energy consumption. Similarly, automatic speed control of pumps and fans can adjust their operation to actual demand rather than running at full speed all the time.
Automated systems for detecting and repairing leaks in steam and compressed-air systems can also prevent energy wastage. Moreover, automation can aid in the optimal maintenance of main engines, ensuring they operate at the most effective pressures. Studies have shown that tuning main engines can lead to 1-2% fuel savings, with even more significant savings in some cases.
As shipowners work toward a zero-emission shipping industry, optimizing onboard energy management becomes more crucial. Energy-efficient practices and automation investment can significantly reduce shipowners' energy use and lower their environmental footprint. While the aim of having a completely emissions-free shipping sector might still be far away, these steps are essential in moving in the right direction, opening up avenues for sustainable and economical marine transport.
