IMO efficiency mandates drive LNG retrofit surge

摘要

Upcoming IMO mandates concerning the efficiency of existing ships is driving a surge in LNG retrofits. Subject to adoption in June 2021, the Energy Efficiency Design Index (EEXI) will be applicable for all vessels above 400 gt and will enter into force in 2023. While LNG retrofitting can potentially apply to all vessels, container ships seem to be more suitable candidates for LNG retrofitting to meet EEXI mandates. As these ships have higher fuel consumption overall, they are also obliged to cut emissions more. Additionally, container vessels represent one-third of the global merchant fleet, making emission reductions from the sector crucial to shippings overall carbon footprint.To leverage the market, many firms in the LNG newbuild sphere are offering LNG retrofit solutions. While the equipment may be similar, project management is often different from that of a newbuild. Much engineering work needs to be done before the vessel is pulled out of service. Many of the details can only be finalised after accessing the vessel, adding to the pressure on schedules. Further, tight schedules demand pre-fabrication and skid mounts, thereby affecting technology choices.
