The list of people who attended the US Navy “Industry forum day” about OTEC on the 15 May, pretty much reads like a ‘who’s who’ in OTEC in the USA. The presentation mentions possible OTEC installations being Diego Garcia, Guam and three locations in Hawaii. The OTEC roadmap at the end of [PDF] the presentation says that the preliminary design is done and they are in the middle of subsystem design with work on CWP (cold water pipe?) and heat exchanger ongoing.
