Starting from January 2023, fresh regulatory benchmarks for enhancing ship energy efficiency, namely the Energy Efficiency Existing Ship Index (EEXI) and Carbon Intensity Indicator – (CII), have been put into action as integral components of the IMO ’s short-term climate objectives.

Ship owners are under significant pressure to bring their fleets into compliance with these regulations and avoid disruptions to their operations. One effective approach to conserving resources and ensuring the ongoing operability, efficiency, and profitability of their fleets is to conduct a thorough analysis of energy efficiency and make the required adjustments. While there is no one-size-fits-all solution, BERG Propulsion can assess potential improvement options and provide support to ship owners during this transitional period. Our aim is to assist you in meeting the EEXI and CII regulations.


EEXI & CII Regulations

Let's Boost Energy Efficiency of Your Vessel

Ship owners face significant pressure to make their fleets comply with these regulations, and avoid interruptions of their operations. Properly analyzing the energy efficiency and necessary adjustment of their current fleets is one way of saving resources and ensuring their fleets’ continued operability, efficiency, and profitability.

While there is no one-size-fits-all solution, we at BERG Propulsion can quantify available improvement options and support ship owners through this transition period. We help ensure that your vessels meet the EEXI and CII regulations.

With our holistic design approach, we minimize mechanical and hydrodynamical losses. We combine the best equipment for the specific application to boost the energy efficiency of the vessel, while not compromising reliability.

Through our comprehensive design methodology, we minimize mechanical and hydrodynamical losses. We carefully select the best equipment tailored to your specific application to enhance the vessel’s energy efficiency without compromising reliability.

Vessels designed to move faster than the EEXI speed limit will experience decreased energy efficiency when traveling below their original design speed. Fuel consumption and vessels performance may be negatively impacted by this. Our energy efficiency solutions can enhance the operational characteristics and save fuel for existing vessels.

The CII annual declaration may negatively affect vessels designed prior throughout their life cycle. To maintain fleets’ operability, efficiency, and profitability, planning ahead is crucial.

Complying with the Regulations

Balancing Performance and Environmental Concerns

At BERG Propulsion we are constantly evolving with shipowners and operators seeking ways to improve the performance and efficiency of their vessels. To balance performance requirements and environmental concerns, vessels can immediately improve their operation profile through engine power limitation, propulsion system and engine upgrades with variable rpm. 


EPL Engine Power Limitation

Engine power limitation plays a crucial role in ensuring sustainable maritime operations. By limiting engine power output, vessels can reduce environmental impact, improve fuel efficiency, and comply with regulations. 

As the maritime industry strives to transition towards a sustainable future, engine power limitation will continue to play an important role in minimizing our ecological footprint.


Propulsion System Upgrades

The primary benefit of propulsion unit upgrades is in their ability to significantly improve efficiency. Integration of the state-of-the-art technologies into existing propulsion systems have proven to be a game-changer in the field of transportation. With benefits ranging from increased efficiency and improved performance to emission reduction and enhanced safety, these upgrades offer shipowners the opportunity to transform their operations in an environment-friendly way.


Engine Upgrades with Variable RPM

Engine upgrades with variable RPM capabilities offer significant advantages for vessels in terms of performance improvement and fuel efficiency. With adjustable engine speed that meets requirements of varying operating conditions, ships can optimize fuel consumption, enhance manoeuvrability, reduce noise pollution in marine environments, and contribute to emission reduction efforts.


Dynamic Drive

Dynamic Drive is a software package for the MPC800 control system. The software automatically and dynamically identifies the most energy efficient settings for the propulsion pitch and RPM to produce the required thrust of the vessel and maintain the required speed. The user-friendly interface enables the crew to set a desired vessel speed and fuel consumption limit. These features ensure consistent fuel-efficient vessel operation between different shifts.

Our analysis entails a thorough evaluation of product efficiency, encompassing the propeller, gearbox, shaft alternator, generators, and engines. Subsequently, we delve deeper into the current system’s efficiency, its overall configuration, and operational performance. We discern crucial areas for improvement and formulate a strategic plan for the next steps. One potential avenue to ensure compliance with regulations is enhancing the vessel’s capabilities for power limitation. To effect substantial change, we will conduct a comprehensive evaluation of available electrical power sources to enhance the vessel’s overall efficiency.

Taking into consideration the ship owners’ commitment to sustainability in their operations, our tailored solutions will be contingent on several factors, including the vessel’s condition, year of construction, its intended and prospective operational profiles. We will also endeavor to anticipate and bridge the gap between the current and future Carbon Intensity Indicator (CII) and Energy Efficiency Existing Ship Index (EEXI) factors. Our comprehensive range of offerings includes cutting-edge hydrodynamic analyses, optimization of the propulsion system (incorporating enhancements from the propeller to the engine), and providing training for the crew.
