Abstract
This invention relates to a subsea actuator with visual position indicators and associated methods for subsea energy infrastructure, such as in the oil and gas industry. The actuator may include a housing with a window, an actuation member, and a drive mechanism that moves the actuation member between at least two positions. The invention also relates to a method that involves providing a housing with a window, connecting the actuation member to a drive mechanism, and indicating the position of the actuation member through the window. This visual inspection can be performed directly or via a camera, even in the event of a power failure, using a passive, unpowered indicator. The indication can be displayed on an ROV panel, ensuring reliable remote monitoring and operation of the subsea actuator.
