Systems and methods for protecting a turbomachine may include a trip throttle valve having a throttle valve assembly and a trip valve assembly. The trip valve assembly may include a plurality of trip valves fluidly coupled to a hydraulic cylinder of the throttle valve assembly via a first flow path and a second flow path in parallel with one another. The trip valve assembly may also include a plurality of isolation valves fluidly coupled to the hydraulic cylinder via the first flow path and the second flow path. The plurality of isolation valves may be configured to selectively prevent fluid communication between the plurality of trip valves and the hydraulic cylinder to allow testing of one or more of the plurality of trip valves during operation of the turbomachine.

Slickline cables and methods for preparing such cables are disclosed. A slickline cable includes a pre-manufactured polymer composite rod having a channel therein; an optical fiber disposed in the channel; a fastener securing the optical fiber in the channel, wherein the fastener is selected from the group comprising a polymer tape, a polymer layer, and a combination thereof, and an outer tube disposed outside the polymer composite rod having the optical fiber therein. A method for manufacturing a slickline cable includes preparing a polymer composite rod having at least one channel therein; placing at least one optical fiber in the at least one channel in the polymer composite rod; securing the at least one optical fiber in the at least one channel using a polymer tape, a polymer layer, or a combination of a polymer tape and a polymer layer; disposing an outer tube over the polymer composite rod.
