A tuned vibration absorber and vibration-reduced pipeline system utilizing same. The tuned vibration absorber includes a support frame, a tuning mass mounted for pivotal movement relative to the support frame about a pivot; the tuning mass including a lever, and a spring contacting the lever. In the vibration-reduced pipeline system, the absorber's support frame is preferably secured atop of the pipeline section, preferably by at least one strap, to absorb vibrations thereof. In a preferred aspect, the tuning mass includes an arm extending from the pivot in a first direction and a weight repositionably mounted thereon. The lever extends from the arm along a second direction substantially orthogonal to the first direction. Preferably the line of action (along A-A) of the spring extends substantially parallel to the first direction. An adjuster is provided for re- adjusting a position of the tuning mass relative to said support frame due to drift in the spring. Preferably, the absorber includes pin means, such as a readily removable pin, for quickly disconnecting the spring as well as pin means for limiting deflection of the tuning mass. A cover including first and second portions houses the tuning mass and spring.
