DNV has announced that it will launch a Recommended Practice (RP) offering a new, accurate and transparent method for measuring, evaluating, and verifying the technical performance of ships in service. The RP is a direct response to the growing regulatory and commercial pressures within the shipping industry to decarbonise operations and establish a standardised, verifiable procedure for evaluating vessel efficiency.

In the wake of the introduction of the Carbon Intensity Indicator (CII) vessels have been rated on their carbon emissions per unit of cargo-carrying capacity. However, the CII is impacted by external factors such as weather conditions, speed instructions, and loading condition, often overshadowing the true technical performance and efficiency of ships.
