GasLog Partners is looking at operating its LNG steam-turbine ships at lower speeds or modifying them to counter the effects of incoming International Maritime Organization regulations.

The moves are being considered ahead of the Energy Efficiency Existing Ship Index (EEXI) and the Carbon Intensity Indicator (CII), which are both measures to cut greenhouse gas emissions.

Speaking in the company’s first-quarter results call, chief executive Paul Wogan said the introduction of the the rules could potentially impact steam-turbine ships as the least efficient vessels in the global LNG fleet.
