How do you build something the size of a skyscraper in the middle of the North Sea? You don't – you build it on land and move it.
Rookie finally hears the story of Troll A, one of the tallest structures ever moved by humans.
In this episode of Offshore Rookie we look at how offshore oil and gas platforms are actually built: steel jackets welded in giant yards and launched from barges, topsides lifted by some of the world's biggest crane ships, and Norway's huge concrete platforms, slipformed day and night in deep fjords and joined with their decks in a spectacular "deck mating".
Then we follow the tow of Troll A from a Norwegian fjord to the North Sea, and see what happens before the first gas can flow: hook-up, commissioning and thousands of checks.
Numbers are rounded and simplified. If you've worked in a yard, on a heavy-lift vessel or on a hook-up crew – tell us what we missed in the comments!
