GRIF used by National Institute of Ocean Technology (India)
Researchers from National Institute of Ocean Technology (India) have used GRIF for the Reliability-Centered Development of Deep
Water ROV ROSUB 6000. You will find this paper in Marine-Technology-Society-Jounal of May/June 2013 (from page 55 to 71).
They have successfully used the Fault-Tree module to compute the probability of failure of their ROV.
