Freeware for Speed/Power trial analysis released

Freeware for Speed/Power trial analysis released

Press Release – January 31, 2014:

The new STAIMO software for Speed/Power Trial analysis and reporting on board has been released today for use by the worldwide maritime industry free of charge, available via a dedicated website

STAIMO is the implementation of the new ITTC – Recommended Procedures and Guidelines for Speed/Power Trials. In the 2012 GUIDELINES ON SURVEY AND CERTIFICATION OF THE ENERGY EFFICIENCY DESIGN INDEX (EEDI), the ITTC Recommended Procedures and Guidelines are considered as preferable standard.

STAIMO has been developed by the STA-Group comprising 38 leading ship owners, operators, yards, class and institutes, which have been cooperating in this field since 2002. With dedicated research on subjects such as measurements, analysis, wind and wave corrections and conversion of results from trials on ballast draught to design draught, this Group led the way to a new industry STA standard introduced in 2006.

Over the last two years the STA-Group has cooperated with the International Towing Tank Conference (ITTC) to develop this method and the underlying approach and models were scrutinised by the world’s leading hydrodynamic experts. The resulting ITTC Guidelines for Speed/Power Trials have been accepted by the IMO as the method to conduct and process speed trials in line with the EEDI rules.
Subsequently, the STA-Group decided to develop the STAIMO software and release this as freeware in order to harmonise the EEDI and speed trial procedures worldwide and to achieve a level playing field.

The software is certified by ABS, which means that ABS has thoroughly checked that the calculation methods used are in strict compliance with IMO rules.

For use on board, the software carries out both analyses & reports can be downloaded from  The Speed Trial Report produced by

The STAIMO software can be verified by anyone via an Internet authenticity check.

MARIN, which assisted the STA-Group in these efforts, also offers a dedicated course for EEDI Verifiers and other stakeholders to allow them to get fully conversant with model tests, speed/power trials and the use of STAIMO.
