<p>The height in the water of a floating building (10) with inflatable walls (13) is adjusted by introducing water ballast (57) at the foot of the walls. The ballast may be provided in the walls (13) themselves, in which case it is introduced and expelled as desired via ports (51, 52, 53). Alternatively a separate water ballast tube (20, Fig. 6) may be provided, the height of which can be adjusted relative to the structure.</p> |
