TVSS is a great investment on any and all the systems and ships represented in this study. The Return on Investment Ratios are all positive and because of the use of all TVSS systems implementation costs are conservative. The payback periods on all but 2 ships are 2.17 years or less and the overall average pay back period is a little more than half a year. The cost savings of the TVSS is ship life dependent, if ship life expectancies are reduced so will the savings from TVSS be reduced. TVSS are low cost items, $2050 per install with tremendous savings potential in terms of maintenance on the systems they protect.
