Statistical minefield clearance is the topic for uncertainty estimations regarding mine hunt and clearance. The uncertainty variables are related to probabilities useful in tactical decisions aids (TDA). Examples of important variables are clearance level, residual mine risk, and on-task-time. In this report the software is presented. Minesim which has been developed since 2010 for estimations of minefield clearance probabilities. The version Minesim2012 also includes sweep estimation functionality. For further development of Minesim, logged data from real minefield clearance operations are important and needed for validation of the simulations. Also in this report A procedure for logging data to Minesim is also presented.
