Steam-turbine LNG carriers will probably need to reduce their trading speed by four to five knots to comply with looming International Maritime Organization regulations.

The Efficiency Existing Ship Index (EEXI) and Carbon Intensity Indicator (CII) come into force in just over 14 months.

While EEXI will apply to all vessels and CII to those of 5,000 gt and above, there is particular interest in how these rules will hit steamships, which number more than 200 and make up one-third of the LNG carrier trading fleet.
