I found this while looking for other information.

I wonder how much vertical lift Ceto 6 would need to withstand as compared to the earlier versions of Ceto?

"The DEPUTY CHAIR — Do they need to be on a solid substrate? You would need to have rock substrate underneath them; is that the plan?

Mr ALLEN — It really just comes down to the site-specific requirements. You can design the foundation in many forms. The simplest form of foundation is the drilled and grouted pile, which then obviously needs a substrate of some type of rock, and then, depending on the consistency added, how deep you have to put the pile. We have looked at the option as well for the site that we are currently deploying out in Western Australia of just using a gravity base. You can go for a gravity base if it is a deep, sandy bottom. There are increased challenges in terms of logistics and getting the gravity base out, because it is a really large base; we need to withstand about 120 tonnes of vertical lift."

That is an interesting Committee Paper, MF. Hadn’t seen that one before. It confirms our discussions and inferences made here post 2009. The plans and specifications of CWE have changed somewhat since then. The laws of physics have not.

The members of the Environment and Resources Committee seemed to understand Greg Allen’s technical explanations. Pleasant surprise for a government committee!

My estimate for the vertical lift the Ceto 6 foundations would have to withstand is at least 500 tonnes. Figure depends on the margin of safety they want to build in.
