The IMO’s greenhouse gas (GHG) levels of ambition are designed to meet specific targets that support the global efforts against climate change and are subject to ongoing reviews. The latest IMO strategy update concluded at MEPC 80 in July 2023.

A range of short-term measures has already come into force and these focus on improving energy efficiency. Short-term measures include the application of technical-efficiency measures for existing ships. This regulation is commonly known as the Energy Efficiency Existing Ship Index (EEXI). Mid-term measures remain under discussion at IMO and, once selected, are expected to come into force in 2027.

When existing designs do not meet the EEXI criteria set by the IMO, shipowners may wish to explore the option of applying an Overridable Power Limit (OPL) to the maximum continuous rating output of the ship’s propulsor. This could prove a simple and cost-effective way to meet EEXI regulations. The IMO Marine Environment Protection Committee (MEPC) in its 76th session distinguished between two different OPL methods: Engine Power Limitation (EPL) and Shaft Power Limitation (SHaPoLi).

The purpose of this publication is to provide best practice guidance for managing the risks associated with the implementation and operation of OPL, based on identified gaps in the newly introduced EEXI regulation.
