I wonder why you wouldn't deploy a spar horizontally, filled with dry ballast powder evenly along it's length, then tip it vertical once in position and pump in water to set the ballast. This seems an obvious approach, allowing use of a shallow dock ,so there must be some issue with it
- lexicality 2y agomy gut instinct suggests that the ballast powder would shift about while being towed and cause unexpected motion, especially if it's hinged at one end. You might end up with it self-deploying with a runaway effect if enough of the weight moved to the loose end
- ajb 2y agoYeah, that's plausible. Maybe it could just be empty, and have concrete pumped into it on deployment. Fun to speculate about, but no doubt there's a problem with that too!
- xnx 2y agoFlip ship does this. I don't think dry ballast powder is needed. https://en.m.wikipedia.org/wiki/RP_FLIP https://en.m.wikipedia.org/wiki/RP_FLIP
- ajb 2y agoYeah, that gave me the idea. The use case is slightly different: flip wants needs to be re-oriented repeatedly, whereas the spar would benefit if its ballast would remain in place without maintenance.
