After sliding down to the base of the sinking structure, immediately begin running along the cable and double jump over the electric force fields and over a couple of obstacles. Then hook swing across the gap to reach the next platform.
Run up the cable, double jump over another force field, and take out the gears that fall onto your path. Spire jump onto a rotating gear point and then begin climbing on another cable. After a short metal walkway, dodge the electric force field, then continue up the wire. Another platform will drop down to make a path to some conduit.
Climb the conduit to the electric current, and wait for it to cease before you head to the next platform. Around the electric current are five rotating blades, each having a spire jump point. Quickly jump across each of them to reach the next conduit.
Take the short walkway to four points with electricity passing between them. Wait for the current to pass the first point, then spire jump over to it. Once you land on the far platform, climb the final conduit, dodging the three electric currents. Once you reach the top, a path will clear for you to take the jetpack. After this, only one mission remains!
