ABSTRACT:
A shallow water drilling barge (46) is supported on a silty water bed (50) of low bearing capacity by providing a submersible platform (74) such as the platform of a jackup drydock (40) with jacking legs (42), floating the jackup drydock into position, ballasting it until it rests on the bottom, floating the jackup drydock into position, ballasting it until it rests on the bottom, floating the drilling barge into position over the platform and floating the barge so that it comes to rest on the platform, with the weight of the barge and jackup drydock as so submerged being less than the load bearing capability of the underlying soil and then jacking down the legs of the jackup drydock to increase its load carrying capability.
