My last loadout before retiring, March 2016:
It would be interesting to see the GZ curves during the ballasting and deballasting sequence.
This would most likely have been a lift-on/lift-off, or possibly skid-on/lift-off operation.
Ballasting sequence are in any case calculated by the Project Engineering office and approved by Warranty Surveyor’s Engineers well in advance of actual operation.
Still it sometimes become necessary to do some changes on the spot some times.
Not very popular and you better know what you are doing when making changes.
I have been both Warranty Surveyor and Superintendent/Loadmaster during loading and discharging operations on Tai An Kou, (some of them tricky) so I know this vessel fairly well. (No, not at the same time)
PS> I still have copies of ballast sequence calculations from a number of loadouts, both flo/flo, lifting and skidding operations, but I’m still bound by non-disclosure agreement so I can’t post any here.
The only time naval officers venture into the weeds of stability apart from a once over lightly is as a submariner. In the surface navy the engineer officer is responsible for stability.
It was a long time ago but my vague recollection is that the centre of buoyancy moved from below the CG to above it and it was vital to keep the CG low while dived.
Guangzhou Salvage is delighted to inform you that their HUA RUI LONG has been safely launched on the 4th October, her significant deadweight of 82,000T associated with a DP-2 will soon be ready to enter the market of high-end ultra-heavy transport.
That looks very familiar…
Somehow I would have expected that Dockwise would have patented the Vanguard design, but apparently that is not the case.

I always use post-conversion Transshelf as an example of how you can, in fact, route exhaust pipes horizontally.
LENGTHENED AMT COMMANDER LAUNCHED AT HAT SAN SHIPYARD IN YALOVA:
Hat San shipyard in Yalova (Turkey) launched the AMT COMMANDER (TBN CD01)
the transport barge is undergoing a major conversion: 15 m lengthening for a total length of 137m; hull strengthening increase of submerging depth in free floating mode up to 12 m above deck. The barge will be owned by Malin Augustea UK Ltd, a JV formed by Augustea and Malin Goup, and will be based in Glasgow. Her first project is the launching of three type 26 Destroyers for BAE systems.
