15:54 On January 19, 1965, Howard Shatto Jr. received a U.S. patent for his "underwater manipulator with suction support device", a groundbreaking invention that paved the way for modern remotely operated vehicles (ROVs) in offshore oil operations. This technology allowed operators to perform complex tasks on subsea wells without putting divers at risk. Shatto's invention played a critical role in advancing offshore petroleum exploration, particularly for companies like Shell Oil, which leveraged ROV technology to access deeper and more challenging reservoirs. The patent ultimately laid the foundation for the multi-billion-dollar subsea robotics market that supports offshore drilling today. By the mid-1960s, global offshore production was expanding rapidly, and innovations like Shatto's manipulator were key in maintaining safe and efficient operations in waters that were previously unreachable.
