Underwater Hydraulic Clamp

One complete 3-second underwater game sound effect: a compact hydraulic arm advances with a restrained servo whine, clamps heavily onto a large salvage object, locks with one deep metal clunk, and leaves a low hull resonance that decays naturally to silence. This must be one single continuous event, not a montage and not multiple impacts. No second collision, no electronic beep, no music, no voice, no ambient background, no clean splash and no cinematic exaggeration. Use a muffled enclosed metal-underwater perspective with a coherent low-frequency body and a natural quiet tail.
