what is thee heaviest?

Question

what was the heaviest manmade thing

Answer 1

Hmmm --- Is the Great Wall of China really a "thing" in the sense of one constructed entity that has some INTEGRAL cohesive aspect to it, or is it an immovable COLLECTION of its constituent parts going up hill and down dale, and indeed one that would in fact BREAK APART if one attempted to move even a part of it?

Might I suggest that two categories of man-made object need to be considered? --- movable and immovable things.

According to www.chapmanspira.com/pov/Norway/norway.htm, "The tallest and heaviest man-made structure ever moved on the surface of the Earth is Norway’s Troll gas platform." The account goes on as follows:

"The structure was so immense that it took ten of the world’s most powerful tugs in the world over a week to tow the hundred-story structure, weighing over a million tons, onto its ultimate production site. It is taller than the world’s tallest building and is the heaviest object ever transported by man. At times, their speed was less than ½ knot for the 180-mile journal, but for the most part the tugs were pulling their cargo at about 2 knots. The tow-out alone went into the Guinness Book of Records as the heaviest man-made object to move on the surface of the earth, displacing the previous record holder, the tow-out of the Ninian (another drilling facility) central concrete platform. The greatest challenge of all was moving it safely from its construction site to its deep-water location 80 km off the Norwegian coast. Its sheer size and weight made its transportation extremely difficult. Yet several novel marine operations were successfully achieved...

...The 369-meter structure now stands in water 302 meters deep and is sunk into the seabed to a depth of 35.7 meters. The whole structure, including the topsides and the flare tower, is 472 meters high. As such, Troll A is the world’s tallest and heaviest concrete platform and the heaviest man-made object ever to have been moved across the surface of the earth...

...This structure is truly a monument to man’s ingenuity. When it was announced in 1986, it was called the "Norwegian Man on the Moon Project." The Economist Magazine dubbed the Troll as one of the 10 technical wonders of the modern world, along with moon landings, the first heart transplant and the jumbo jet. Not bad company."

Live long and prosper.
