ISO 15016:2025 Improved standard for speed/power trials
Conference/JournalMARIN Report 144
Date30 Jun 2025
Following a four-year revision, the IMO MEPC83 accepted ISO 15016:2025 as the new standard for EEDI speed/power trials in April 2025.
This modernised standard was published by the ISO after a revision conducted by a working group consisting of 40 international experts originating from all stakeholders (www.iso.org). This third edition creates a level playing field for EEDI and newbuilding contracts.
Over the last two decades MARIN contributed essential R&D to arrive at a uniform standard for speed/power trials, with the target to assess ship speed within 0.1 knots and propulsion power within 2%.

Correction methods improved for wind and waves
In the four-year revision process, the results of STA’s R&D and validation work carried out by the ITTC over the last decade have been implemented. Correction methods for wind were improved and new wind limits have been introduced in combination with specified wind sensors. With the use of Lidar for undisturbed wind measurement or the use of 3D ultrasonic wind meters higher wind speeds are allowed.

MARIN | MV Maxima, Royal Wagenborg
Days after our queen christened the MV Máxima, Royal Wagenborg kindly provided MARIN time on board to perform research within Green Deal, looking into the accuracy of full-scale ship performance. With sea state and current measured from a hydro-survey vessel, we performed different trial runs throughout the day. This work will aid future research such as our new STA-2 Joint Industry Project (JIP) on speed trial methodology. This project aims to improve the current standard for speed/power trials. Within the STA 2 JIP new correction methods will be investigated, where needed newly developed, and validated.
