The Rippers can be killed with three Power Bombs, or one carefully placed Power Bomb, Gravity, and a careful dodge of the top-most Ripper. With a single Power Bomb, IBJ from the water to avoid the first Ripper, then place the Power Bomb at least two tiles above the next. This can be achieved with a Staggered IBJ. Then climb the right side of the shaft and similarly dodge the top Ripper.
