This chapter has been written by three invited co-authors who have addressed underwater connector selection from three distinct perspectives: the end-user, the manufacturer, and sales engineering. Our deepest thanks go to Kevin Hardy, President of Global Ocean Design, Cal Peters, Director of Engineering for Falmat, and Brock Rosenthal, President and founder of Ocean Innovations. They have lectured on the subject of “cables and connectors” at numerous Oceans MTS/IEEE conference tutorials. (These tutorial presentation materials form the basis of this chapter. Additional information on this team is provided in the Acknowledgments section.)
