    I’ve had an idea for a system that might make these platforms more stable at sea. Basically, the idea is to have a series of holes in the hull that lead to water-tight tubes. In these tubes are stoppers on extendable arms. For normal balance, these arms are fully extended, stoppering the hole. However, should the platform tip to one side due to a wave, an arm on the other side contracts, unbalancing the platform forcing the formerly upended side to sink, re-balancing the craft.

    I’ve had another idea that uses the same basic concept to move air around chambers in the hull, causing increased buoyancy in the sunken part of the platform, but the hull-breach system strikes me as cheaper and simpler to implement. Either way each plug would be connected to a computerized balance-detection system to orchestrate the whole affair. I’m not sure either system would do much for a big storm or tsunami; I’m hoping the displaced water caused by the re-tilting will go under the rest of the platform, essentially causing it to rise above any really, really big waves. I’m no expert in engineering or the deep sea, so these ideas may be completely foolish and innefective. Still, if not, I hope they help. Your thoughts? Thanks.

    Look at a bent axis hydraulic pump and replace the swash-plate with a rotating cam.

    If this is preferable to a large number of independant piston pumps: I don’t know.

    Probably not, but cool anyway. For our objectives: centrifugal pumps purging ballast on the sinking side of the ship may be another good way of approaching the problem.

    Is this similar to how cruise ships do it? I’ve been doing a lot of research lately on anti-roll water tanks and active stability systems that use pumps to move water around to counteract the rolling motions, and those use internal tanks rather than breaches in the hull.

    You idea sounds like the same idea, so I don’t see why it wouldn’t work.

    Save yourself the trouble and just build your seastead at the bottom of the ocien in the first place. :P

    if you let water from the outside to lower it you end up with a loss of bouyancy. just put a tank on each side and pump water from the low side to the high side. you would have to pump it anyways you keep your ship from sinking. and useing to tanks you pump less water as you are not only redoncing the bouancy on the high side but increaseing it on the lower side as well.
