N2  - The bulk carrier fleet faces a lot of challenges to cope with the strict GHG emissions implemented by IMO. The EEDI rules for the newly designed ships and EEXI regulations for the existing ships are considered to be the strictest for the bulk carriers and operating efficiently as well as comply with the rules can be very difficult. A comparative study of the EEDI values for bulk carriers and container vessels are carried out to depict the limitations faced by newly designed and existing bulk carriers. Also, the lowering of speed of the bulk carrier to reduce maximum power output of the vessel is discussed and how it may not be effective on a long-term basis is discussed with respect to the Minimum Power Requirement guidelines for a bulk carrier. Furthermore, the alternative options for replacing the conventional bulk carrier design are discussed which includes usage of alternative fuel instead of heavy fuel oil, usage of wind power and implementation of hybrid systems onboard the ship. The economic aspect of these alternatives is discussed. As for the existing bulk carrier fleet the compliance with EEXI regulations is checked and suggested alternative is discussed, which mainly includes retrofitting or decommissioning of the vessel, based on the evaluation of profit margin. From the respective analysis, a suggested solution is provided which includes a hybrid system utilization as well as encourage short voyages instead of a long one which is typical for bulk carriers in order to minimize the limitations faced by the bulk carrier fleet.
