RE: MSC Leandra v28 Jun 2023 16:12
Hi StockCheque/Haggis, the advice previously was that the full LONO would take 6-8 months (4,000 hours of engine time).
The wide range in time estimations is because:
- It depends upon the route, routes with long uninterrupted stretches are good for burning through the hours faster (this proposed route looks very good for that).
- How efficient the ports visited are (i.e. if you're straight in and out, then you spend less time idling in anchorages). Again, European ports are usually extremely fast; contrast that with the time Leandra got stuck in Port of Durban for about a week because she was in general purpose segment of the port rather than the container terminal. Huge difference!
- Restrictions: such as emissions control areas (ECAs), ports that forbid scrubbers, etc.
We're in a really strong position this time due to the new scrubber that has been installed.
If this route is the LONO one (of course, it could change), Leandra will spend a very large portion of her sailing time in ECAs (North American, North Sea, and Baltic Sea, 0.1% SOx ECAs); in these zones unscrubbed vessels cannot even use 0.5% ULSFO; instead they need to switch to extremely expensive LS-MGO (low sulphur marine gas oil — similar to diesel).
Except for ports that restrict open loop scrubbers in very small areas (and I am not aware of any of those being on the list), Leandra will be able to use high sulphur residue in her MSAR/bioMSAR formulations without needing to switch fuels. That obviously means lots of additional hours of engine time on bioMSAR/MSAR.
Hope that makes sense!
