The Energy Efficiency eXisting ship Index (EEXI) is a new IMO regulation that aims to reduce CO2 emissions of existing vessels by setting minimum requirements for technical efficiency.

EEXI comes into force on 1 January 2023. Any vessels over 400Gt failing to meet the requirements between this date and 31 december 2023 (depending on the schedule of their first survey during this period) risk being detained in port and fined.

MAN PS provides MAN OPL solutions for MC and ME engines needed to become EEXI compliant. As your trusted partner, we will support you with the solution and installation, saving you time and money, and provide guidance on how our retrofit modifications for EEXI can also contribute toward an optimal Carbon Intensity Indicator (CII) rating.

 

Dorte Kubel explains how EEXI can affect you

Time is running out

The EEXI deadline is approaching fast, and time is short to avoid a potential retrofit installation bottleneck as other shipowners get on board.

Don’t wait - contact our specialists to start the compliance process now.

EEXI Flex Solution

MAN PrimeServ offers an EEXI Flex Solution for all vessel- and MAN engine types. EEXI Flex is a solution that requires the vessel to limit its engine power to achieve EEXI compliance, however the owner wishes to undertake on their own the EEXI assessment report and EEXI technical file. This solution includes MAN Overridable Power Limitation (OPL) for either MC or ME type engines.

As the original designers, we know your engines better than anyone else, which means you can have complete confidence in the reliability and performance of your compliance solution.

MAN OPL MC

OPL-MC
MAN OPL for MC is a measure to limit the main engines Maximum Continuous Rating (MCR), with the possibility
to be overridden if safety of the vessel is compromised. The MAN OPL is a mechanical stopper device for limiting the fuel index. It is easily overridable and tamper proof.

 

The OPL stopper is installed on the original fuel index stop and can be removed if full engine power is required. Once removed the original fuel index stop is revealed and full engine power is available.
The OPL stopper is secured and locked by a unique wire seal with parts number and IMO number. The wire seal can only be installed if the OPL stopper is secured in the correct position.

For MC engines, the OPL solution allows easy release and secures the reset of power limitation with no risk of
overload.

MAN OPL ME

 

MAN-OPL-ME
MAN OPL for ME engines is a solution that consists of software and hardware, where the engine power is limited
electronically by installing a new software release and parameter file. The OPL is controlled by a remote operating panel consisting of a switch and control lamps that are installed either on the Bridge or in the Engine Control Room (ECR).

 

MAN OPL is a measure to limit the main engine’s Maximum Continuous Rating (MCR), with the possibility to be overridden if safety of the vessel is compromised. For ME engines, the engine power is limited electronically by the engine control system (ECS).

The MAN OPL can be released and reset from Bridge or Engine Control Room. In the Engine Control System (ECS) it is possible to limit the engine power. The ECS is constantly calculating the load of the engine, based on the engine speed, fuel index and cylinder pressures (if applicable). Until the power limit is reached the fuel index will remain unlimited.

Cll

cll-ratingAlong with the EEXI, the Carbon Intensity Indicator (CII) will enter into force from 2023. CII is defined as CO2 emissions per transport task (CO2/dwt x nautical mile). It is calculated based on a vessel’s mandatory annual fuel report to the IMO.

With the introduction of CII, vessels will be rated from A (best) to E (worst). This rating can have a direct effect on the vessel’s commercial value, in terms of fuel efficiency, charter value, insurance cost, port fees, and depreciation. Vessels rated D for three consecutive years or vessels rated E will have to make a plan to improve their rating.

If your vessel requires modifications to meet EEXI standards, it is advisable to use this as an opportunity to invest in solutions that contribute towards an optimal CII rating. Our experts can help you to understand what is possible and the benefits it can bring to your business over the longer term.

Assessment reports

primeserv_marine_serviceMAN PrimeServ can help you create an EEXI assessment report, no matter whether or not you use a MAN engine, based on information you provide about your vessel. 

Depending on the calculated EEXI, the assessment report will suggest how you should proceed. Possible outcomes of the report include an EEXI technical file, MAN Overridable Power Limitation and other retrofit solutions required to meet the necessary standards. If you purchase one or more of these upgrades, your assessment report will be free of charge. Furthermore, it will be possible for you to buy an EEXI engine study, which offers a more comprehensive engine-specific report on the possible retrofit solution. The EEXI assessment report will also include proposed MAN Energy Solutions products for improving the fuel consumption of the engine and thereby contributing to improving the CII, and pre-inspection formulas for validating the applicability of the suggested solution(s).
