New Ship Will Remain Stable By Creating Its Own Inner Waves

Posted by Soulskill on Friday September 6, 2013 @08:30AM from the wave-of-the-future dept.

Zothecula writes "When offshore oil drilling rigs are being installed, serviced or dismantled, the workers typically stay in cabins located on adjacent floating platforms. These semi-submersible platforms are towed into place (or travel under their own power) and then their hulls are partially filled with water, allowing them to remain somewhat stable in the pitching seas. Now, a ship is being built to serve the same purpose, but that will be a much more mobile alternative. It will keep from rolling with the waves by generating its own waves, inside its hull."

Power requirements? by danceswithtrees · 2013-09-06 09:21 · Score: 5, Informative

The system pushes water from side to side using compressed air to counteract rolling from ocean waves. Granted this is for use in drilling rigs (read big money), but I wonder how much power is required to run the air compressors. The compressors have to be high flow to rapidly move a lot of water, albeit at relatively low pressures-- only 4.4 psi required to generate 10ft difference in seawater (this does not take into account viscosity and inertia).
