Feet patter across three information-packed floors stacked inside the Ocean Star, a former drilling rig that spends its retirement as a museum and education center on Galveston's Pier 19. After two decades drilling in the Gulf of Mexico, the rig has since been revamped and outfitted with interactive models and displays that illustrate the story of offshore oil, gas, and the energies that lurk beneath the world's oceans. Visitors can tap into videos for explanations of drilling, geology, and seismic topics, or stand next to scale models of production platforms. In addition to its lineup of eye-popping sites, Ocean Star Offshore Drilling Rig Museum and Education Center harbors ongoing exhibits showcasing the industry's careers, history, and safety measures. Self-guided tours seven days a week enable guests to explore the rig's nooks at their own pace, while an onboard staff stands by to answer questions and courteously laugh at all petroleum-related knock-knock jokes.
