While technical performance, initial capital investment, and installation costs are often considered during suppression device selection, maintenance costs and their impact on the total net present value cost of suppression devices are often ignored. This paper discusses various installation and maintenance aspects of suppression devices selection, and then presents results from a fairly straightforward economic analysis of the various trade-offs that should be considered during device selection. These results should produce more thoughtful and mature decisions on suppression device trade-offs and their ultimate design. Hybrid systems should continue to grow in popularity, as both helical strakes and fairings can enjoy advantages depending upon the geographical location, performance criteria, cleaning methodology, and water depth.
