According to DNV, verification of a ship’s attained Energy Efficiency Existing Ship Index (EEXI) takes place at the first annual, intermediate or renewal survey, which is on or after 1 January 2023. However, some shipowners face challenges to install the required equipment on board within the required deadlines.
In particular, this happens due to a global shortage of electronic components or non-availability of service technicians, e.g. limited docking capacities. This statutory news addresses how to deal with this issue.
The aim of the Energy Efficiency Existing Ship Index (EEXI) is to measure ships’ energy efficiency. However, different measurements apply for different kinds of ships.
The regulations formally do not offer postponements of EEXI compliance, due to unavailability of equipment for instance. However, if such situations should occur, DNV supports an interim EEXI compliance method which is based on continuous power monitoring and data-reported compliance verification. As this method is not formally regulated by the IMO, it needs the formal acceptance of the vessel’s individual flag on a case-by-case basis.
As explained, pending acceptance by flag, DNV supports issuance of a full-term International Energy Efficiency Certificate (IEEC) in combination with an Interim Exemption Certificate. The Interim Exemption Certificate temporarily exempts the vessel from requirements of the guideline on shaft/engine power limitation system (MEPC.335(76)). It also requires the vessel to follow an alternative compliance scheme until the final installation(s) can be verified. The proposed validity of the Interim Exemption Certificate coincides with the next IAPP survey.
The full process is illustrated in the below figure and consists of the following steps (may be subject to change as per agreement with flag):
- A letter from the equipment maker or service supplier will be required to confirm the non-availability of components to complete the installation, together with a procedure on how to capture data from the system to enable the proper verification of used power.
- To enrol in the scheme, flag acceptance is required.
- Upon acceptance by flag administration, an interim OMM based on the maker’s procedure describing the interim compliance scheme is to be submitted for approval.
- When completing the first IAPP survey on or after 1 January 2023, a full-term IEEC will be issued by a DNV surveyor, in combination with an interim exemption certificate. This interim certificate will show exemptions from requirements of the EPL/Shapoli guideline by the IMO and refers to the interim compliance scheme instead.
- The vessel will now enter a new 3-monthly survey scheme following the exemption certificate, whereby records of the actual shaft power used will be submitted for verification by DNV through a remote survey request. Possible means to provide the required data are, for instance, time plots of a torque meter or electronic engine logs.
- Upon successful verification of the power logs, DNV will issue a survey report confirming the vessel complied with the required power limitation within the verified time. The verification cycle will be repeated every 3 months until the permanent installation can be completed and verified on board, although limited by the validity date of the exemption certificate.
