STAIMO versions older than 2.3.0 should no longer be used.

STAIMO is freeware for the analysis of speed-power trials of ships. It is the implementation of the ITTC Guidelines 2014 and ISO 15016:2015 which have been accepted by IMO MEPC68 for EEDI.

STAIMO has been developed on behalf of STA-Group (39 ship owners, operators, yards, class and institutes involved in sea trials).
Since 2004 STA-Group has initiated R&D to improve and unify delivery trial analysis methods. Over the last five years STA-Group has been working closely with ITTC and ISO to develop the standard for EEDI speed/power trials required by IMO.

STAIMO 2.3.0 is compliant with IMO MEPC and can thus be used to derive both Contract speed and EEDI speed.
