Standards for vessels and carbon emissions are achievable thanks to the expertise and range of solutions provided by Kongsberg Maritime

Meeting EEXI and CII standards

Regulations governing reductions in carbon emissions are becoming ever more stringent and ship owners will have to move quickly to achieve them as they have very little time to spare. Meeting the new EEXI and CII standards will require preparation and Kongsberg Maritime has the expertise and solutions to help

The world of shipping is changing. The climate emergency means that vessels will have to cut their levels of greenhouse gas emissions (GHG) more quickly than ever, a move now being enforced by legislation.

New regulatory standards for vessel energy efficiency will take effect from January 2023 as part of the short-term ambitions of the International Maritime Organisation (IMO) to reduce carbon by 2050 – the timescale that is rapidly becoming the standard global target for net zero.

The new standards are known as the Energy Efficiency Existing Ship Index (EEXI). The separate Carbon Intensity Indicator (CII) is the rating scheme for the operational efficiency of a ship. It is estimated that more than 30,000 vessels will be affected by these.The new standards are known as the Energy Efficiency Existing Ship Index (EEXI).

Ship owners will have to act quickly. The timescales are short – merely a matter of months away – and preparation is clearly going to be needed in terms of compliance in order to deliver on the operational, commercial and time requirements of these new rules. Kongsberg Maritime has the expertise and broad range of solutions to help with this. 

As with the Energy Efficiency Design Index (EEDI) which applies to new-builds, the EEXI is evaluated based on the vessels’ design parameters such as equipment and technical data. It will be relevant to most cargo and passenger vessels above 400 gross tonnage falling under MARPOL Annex VI. Non-compliance can lead to fines and a possible interruption of the vessel’s operations.

The timescales may be relatively short – and to complicate matters further there also is a planned revision of the EEXI and CII rating scheme and the efficacy of actions by the IMO in 2025. Preparation for the new regulations need not be costly, cumbersome or onerous. Preparation for the new regulations need not be costly, cumbersome or onerous.jpg

Compliance with EEXI can be achieved through a number of measures of which the fastest, easiest to install and most economical are power limitation solutions.

Technologies for sustainable oceans

Kongsberg Maritime is committed to developing the technologies for sustainable oceans. We provide a range of comprehensive offerings as well as expert guidance. Our services allow ship owners to make the most informed decisions quickly and within the allotted time frames in order to optimally benefit both their vessels and their operations.

Our solutions include Engine Power Limitation (EPL), which was developed in order to enable vessels to quickly and simply comply with the EEXI requirements by limiting engine power and associated emissions. 

Our EPL offering is available in the AutoChief Digital Governor System (DGS) and CanMan propulsion control system. It enables a ship to limit its engine power output when the pre-set limit is reached, helping operators to keep control of their vessel’s level of emissions in operation. 

The upgrade to the EPL function is available for cargo and passenger ships in order to enable a swift and cost-effective compliance with the 2023 IMO greenhouse gas regulatory measures.

This functionality is available for AutoChief C20 DGS and AutoChief 600 DGS delivered for MAN B&W MC and Wärtsilä/Sulzer RTA engines. It is also suitable for all engines delivered with CanMan systems with load control. 

Shaft Power Limitation (ShaPoLi) is another functionality that is available in the CanMan, AutoChief C20 and AutoChief 600 remote propulsion control systems. It allows a vessel to limit its shaft power output when the pre-set limit is reached, so helping operators to keep control of the level of emissions from a vessel while it is operating.

ShaPoLi enables optimisation of a ship’s propulsion and blade design and brings additional fuel savings and a reduction in carbon dioxide emissions.

The ShaPoLi offering enables optimisation of a ship’s propulsion and blade design to the fullest. It also brings additional fuel savings and a reduction in CO2 emissions.The ShaPoLi offering enables optimisation of a ship’s propulsion and blade design to the fullest.jpgThe installation of the function can also bring swift and cost-effective compliance with the IMO’s mandatory EEXI measure, so setting new requirements for the reduction of existing ships’ carbon emission intensity.

We also deliver MetPower, the torque/power metre that is system dependent and has the functions required for the limitations needed. It supports ShaPoLi functionality either as a standalone offering or when integrated with other KM products.

The Carbon Intensity Indicator (CII) will apply to all cargo, RoPax and cruise vessels above 5,000 gross tonnage that are trading internationally. It is an annual indicator of the ship’s transport efficiency, rated from A (best performance) to E (worst performance) and expressed in grammes of CO2 emitted per transport capacity and distance.

Zero emissions

To qualify for the highest ratings, measures taken can include the installation of more energy-efficient products, systems and technologies on board. Other measures also involve the adoption of cleaner power sources or the complete alteration of propulsion systems with hybrid or zero-emission solutions.

While the EEXI is a one-time certification covering design parameters, the CII is given based on the actual emissions of the vessel during operation and will be revised annually.

Implementing actions in order to achieve EEXI compliance provides a good opportunity for ship owners to prepare their vessels to achieve favourable CII ratings. 

The requirements of the CII scheme are intended to become increasingly stringent over time in order to meet the IMO’s initial emission reduction goals leading up to 2050. 

Implementing actions for EEXI compliance will provide an opportunity for ship owners to prepare their vessels to achieve favourable CII ratings. It will also help them to remain environmentally compliant in the long run, gain operational efficiency and increase commercial value in an optimal and prepared way.
