EEDI, EEXI and CII: Improving Environmental Ratings with HeatPower

Minimizing Environmental Impact with Sustainable Technology

Regulating the environmental impact of the shipping industry may be nothing new, but the introduction of new rules and the strengthening of existing measures is transforming the sector in a bid to accelerate decarbonization. Since the International Maritime Organisation’s (IMO) focus on energy efficiency in MARPOL Annex VI, there has been a flurry of environmental regulations, targets and limitations implemented from a variety of sources.

Energy Efficiency Design Index (EEDI)

Used to ensure new-build ships achieve a ‘minimum energy efficiency level per capacity mile’, the EEDI sets standards in the form of a Required EEDI rating, based on the type and size of the vessel. To achieve compliance, a vessel’s actual or ‘attained’ rating must be equal or better to its corresponding required rating.

• Shipowners, operators, and shipyards are under pressure to mitigate their environmental impact or face pecuniary sanctions and/or commercial disadvantages.
• A vessel’s environmental impact is a top priority throughout its entire lifespan.
• Latest emissions-reduction technology can enable shipowners, operators, and shipyards to meet the requirements of increasing environmental regulations and enhance the sustainability of their operations.

Energy Efficiency Existing Ship Index (EEXI)

The EEXI measures the energy efficiency of existing vessels based on their technical design. Essentially, it is the equivalent of the EEDI for ships in operation and imposes retrospective energy efficiency requirements on active fleets.

• Shipowners may need to make significant modifications to improve the energy efficiency of the vessel and secure an optimal EEXI rating.
• Not all sustainable technology is viable for retrofit projects.
• Climeon’s HeatPower 300 technology allows shipowners to enhance the energy efficiency of existing vessels via accelerated integration, low payback periods, and streamlined retrofit applications.

Carbon Intensity Indicator (CII)

The carbon intensity indicator determines a vessel’s energy efficiency by assessing ‘grams of CO2 emitted per cargo-carrying capacity and nautical mile’. Ships are subject to a ’required annual operational CII’ but 2024 is the first year that ‘attained annual operational CII’ verification will take place.

• Climeon’s HeatPower 300 system can assist shipowners in securing favorable CII ratings by cutting fuel consumption and reducing CO2 emissions.
• When a vessel’s annual fuel consumption and CO2 emissions factors are improved, the corresponding CII calculation and rating is also enhanced.

Achieving Environmental Compliance with Climeon’s HeatPower 300 System

A significant proportion of waste heat is generated on board any operational vessel and the majority of this waste heat is produced at relatively low temperatures.

• Climeon’s HeatPower 300 technology is built for challenging on-board environments and simplified integration, which reduces payback periods and enhances ROI.
• With the potential to cut fuel consumption by 1300 mt/yr and reduce CO2 emissions by 100,000 mt over the course of a vessel’s lifespan, Climeon’s HeatPower 300 technology enables shipowners, operators, and shipyards to meet environmental regulations, secure enhanced EEDI / EEXI and CII ratings, and transition to a more sustainable future.
