The Lem65ePlus-SDARI Methanol design, a joint development of Lemissoler and SDARI explores the feasibility of using methanol as fuel to reduce carbon emissions to reach the IMO’s net-zero target by 2050. With the implementation of EU ETS and FuelEU regulations, the vessel, when burning green methanol will have a high potential to reduce carbon emissions-related costs. The vessel has been thoroughly optimized and its preliminary Energy Efficiency Design Index (EEDI) was reviewed and indicated that it exceeds well EEDI Phase 3 standards. ABS completed design reviews based on class and statutory requirements.
