Having managed a Flo/Flo for the USN, I would say YES but NOT like the MLP nee ESD above!
A clear deck aft, semi-submersible can perform several valuable roles. For the Brits, the obvious one is to lift a warship to a rear area for BDR – Battle Damage Repair. A Flo/Flo can lift amphibious craft in some numbers to where needed (complimenting the landing craft spots on amphib warships. A Flo/Flo can lift pre-outfitted barges as TD has shown before to forward areas. Those barges could be MTF – Medical Treatment Faciliites. They could be MRF – Mobile Repair Facilities. They could be a MOBASE – Mobile Base for small craft operations. Or they could simply be YO – oil barges or cargo barges for use in a damaged port facility.
While a semi-submersible can come in many forms, the keys to its performance is a specially contoured hullform and the most modern of ballasting systems. What the Navy has also found is a need for additional accomodations for supercargo persons. I would try to add a small flight deck and some cranes.

What’s the Parent Vessels class and is it Proposed to be used. And is there going to be an Over Head Decking similar to the USN’s ESB (Expeditionary Sea Base) Vessels…

secund… The parent design was NASSCO’s Alaska class tankers. The central hull was cut out supposedly to provide a Flo/Flo capability for the MLP nee ESD. The type of modification has been the poor man’s route since the 1990s. Having a structure fore and aft Limits the cargos which can be lifted. As important are the semi-sumersible unique hullforms used by then Dockwise now Boskalis.

None of the above were incorporated into either the ESD or AFSB need ESB classes. To make matters worse each ship ended up costing approx. $500 million which is much more that the Should Cost evaluaiton for an unarmed auxiliary.
To make matters worse, when the Puller showed up in Bahrain, CENTCOM had it commissioned in order to perform missions they wanted done.
So the USN has spent about $1.5 billion on ships with highly specific but limited capabilities.
