The guide outlines strategies across ship design, operations and maintenance. 

Key areas in design include:
- improved boil‑off gas management
- hull and cargo capacity optimisation
- propulsion efficiency
- evaluation of alternative fuels
- consideration of future onboard carbon capture. 
Operational efficiency is a central theme, particularly in voyage planning and cargo discharge.


The publication aligns closely with IMO EEDI, EEXI, CII and SEEMP and provides practical pathways for owners and operators seeking measurable efficiency gains while maintaining the high safety standards that define the liquefied gas sector.
