New Calculator Launched to Aid Ship Owners Comply with New Standards

Yet another acronym has recently found its way into the maritime vocabulary, EEXI, which stands for the Energy Efficiency Existing Ship Index, but this one needs serious consideration by ship owners. A Regulation adopted at MEPC76 this week is due to take effect in January 2023.

Ratification of the standards required is a medium-term component of the International Maritime Organisation’s (IMO) roadmap towards reducing global shipping’s carbon intensity by 40% over the next decade, using 2008 as a baseline. The 76th meeting of the IMO’s Marine Environment Protection Committee (MEPC 76) confirmed the Regulation and so certain was classification society DNV of approval it launched an EEXI Calculator in advance of the vote.

EEXI, as opposed to the Energy Efficiency Design Index (EEDI) which has been in place since 2013 setting newbuild standards, is to assess the energy efficiency of existing ships, focusing solely on their design. It determines the standardised CO2 emissions related to a vessel’s installed engine power, transport capacity, speed, and degree of energy efficiency.

The Regulation will be applicable for all cargo, Ro-Pax and cruise vessels above 400 gross tonnes, depending on their propulsion type and whether they trade internationally. DNV estimates that currently up to 30,000 such vessels need to take action to comply with the EEXI Regulation. Knut Ørbeck-Nilssen, CEO of DNV Maritime explained why the company felt the calculator was necessary:

“The EEXI is putting a great deal of pressure on ship owners to take immediate action in order to analyse the energy efficiency of their fleet and make any necessary adjustments to ensure compliance. At DNV, we understand the difficulties the industry faces in meeting this regulatory deadline. This is why we have tailored our new EEXI Calculator to meet this need.”

The DNV EEXI Calculator is purpose made for high volume ship segments such as tankers, bulkers and containers. Customers can access this newly launched tool via the Veracity portal under ‘Fleet Status’. The calculator can produce an EEXI calculation and the technical file based on the data uploaded by the customer.

For more complex cases, and when the customer wants to save time and effort, DNV’s advisory experts can work with customers to map out a pathway to compliance, identify the correct parameters for the calculation, and assist in preparing the required documentation. Fabian Kock, Head of Section Environmental Certification, DNV Maritime concluded:

“These two pathways are designed to help everyone tackle their EEXI challenges in time to reach compliance. For companies with a younger fleet, this may not require major adjustments, they can easily access and prepare the required documentation through our EEXI calculator.

”And for those who need more support, there is the opportunity to tap into DNV’s extensive expertise as they prepare to make more involved decisions around how their vessels can meet the regulatory requirements and secure EEXI compliance when the Regulation comes into force.”
