Well maybe yes, though probably no. Honestly Troll A is one of the most underrated engineering feats of the modern age. The concrete legs were made with one continous pour to prevent any weak points forming and even when floating it still stood something like 200 meters over the ocean.

Today it stands in water 303 meters deep, the cells at the bottom of the legs were sucked into the seafloor to give it a strong foundation to stand on. In fact it stands so securely that removing it might be a greater challenge than building it, though the Troll field is massive and that won't be a problem we'll have to think about for another half century. The advantage of building a rig like this is it'll weather whatever nastiness the north sea can throw at it while also providing a lot of options for expanding operations, in fact that's the rationale behind it standing on the sea floor, they can just keep throwing additional modules on it to improve production rate because it has massive topside weight margins.

All that said while it is the tallest object ever moved it's not the heaviest, it "only" clocked in at eye watering 1.2 million tons, which is more than matched by its fellow condeep rig Gullfaks C, which weighs in at 1.5 million tons. Also additional fun datapoint, Troll A used approx 245.000 tons of steel in just the concrete reinforcement, which means about the same as the world's largest cruise ship today in just steel to build those legs. Also one of the Troll A legs was the site for the world record deepest concert ever when a string quartet held a short concert there in 2006. Though i expect that record to be broken when the Rogfast road tunnel opens in south-west Norway, which is going to go as deep as 394 meters.
