Attached to the main illustration there are 17 words under the heading "Seabed suitability". They are:- "Some seabed preparation may be required in advance to ensure the ground is level prior to installation".
I am sure that I do not need to forewarn the distinguished members of the consortium that have been working on these alternatives, that, the subject of the 17 words will constitute 90% of their problems.
The equilibrium of floating bodies is textbook engineering; what one encounters on the seabed is not.
