It can't possibly be new. Multi-billion dollar construction projects are fairly common and that kind of capital investment makes people very clever.
Oil rigs definitely follow the prefabrication and then float-into-position approach, and have been doing that for a long time.
I'm sure there's a good reason why it's more cost effective or feasible to do this instead of drilling a tunnel under the seabed.
- Taniwha 5y agoNot new - as mentioned above the BART trans-bay tube was built this way back in the '70s
- mstade 5y agoTo your point of this technique not being new: the mulberry harbors the allies built following the d-day invasion of operation overlord made use of prefabricated sections code named phoenix, that were towed into place and then sunk to form the structure of the harbor. They were so named, I think, because after being built they were sunk off the coast of England before being refloated in preparation of the operation, i.e. like the phoenix the rose, or something poetic like that. If you're ever in or around Normandy I highly recommend a visit to the beaches. They're much bigger than I had imagined, and it really hit home then what a massive operation it was. Anyway – no, the technique is not new.
