When is the proposed cut-off date for EPLs adhering to your previous acceptance criteria (for example a vessel undertaking a second EPL)?
The above acceptance criteria will be effective from Tuesday 30 June 2020. Any EPL requests that do not meet the acceptance criteria after this date will not be accepted.
What is the process for a ship owner who has undertaken a level 2 minimum propulsion power assessment?
We require the above acceptance criteria be met before any benefit from an EPL will be applied in our system. This means we will only accept EVDI calculations to a maximum of level 1 assessment. A vessel owner will therefore be required to obtain documentation to support a limitation to no greater than level 1.
Will EPLs to level 2 assessment that already exist still receive a benefit to the GHG Rating?
RightShip require owners to ensure they adhere to the EPL management plans and continue to meet EPL acceptance criteria. As part of this process, RightShip is increasing the review of the periodic surveys and the adherence to the EPL management plan. This process will include a periodic review of vessels limited to level 2 requirements.
How can I improve my vessel’s GHG Rating, other than by an EPL?
There are various energy saving equipment options for shipowners to consider in terms of improving the GHG Rating. The energy saving equipment will need to have a positive effect on one or more of the elements contained in the EEDI/EVDI equation. (See guidelines). For example, the speed of the vessel, engine size, specific fuel consumption etc. so that the vessel is operating more efficiently than first designed.
The main energy saving equipment categories that can lead to a GHG Rating improvement include:
- ‘Major conversion’ (e.g. alter ship dimensions, cargo carrying capacity or engine power)
- ‘Mechanical/electrical measures’ (technological measures for improved energy efficiency e.g. propulsion improvements)
Note: The benefits from ‘operational measures’ such as low friction paint, cannot usually be isolated from the EVDI equation and will generally not improve the GHG Rating. They may however qualify your vessel for a plus (+) symbol next to the GHG Rating, to signify that it is operating more efficiently than designed.
For us to include this improvement in your vessel's rating, we require documentation from class or a qualified third party detailing the improvement to the vessel. This can take the form of a re-sea trial or CFD modelling. It needs to be vessel specific and outline how the energy saving equipment improves the efficiency of the vessel under EEDI/EVDI conditions e.g. the Vref at 75% main engine MCR at summer load draught.
