That is true as it stands, but I am assured that the it is possible. My understanding is that BAE has already looked at the graving dock and have a proposal that will allow for an extension to accommodate the extra 30m or so required.
But would it be worth the investment? How often would an extended graving dock be used to construct large ships again?
I tend to agree with Volkodav, why not expand the more modern yards with plenty of space to grow at both or either Henderson and Techport?
For example, Techport, yes the site is currently mostly occupied by ASC, but as the site is owed by the SA Government, there is nothing stoping BAE putting in a bid to build Cantabria type ships and then use the common user facility to assemble the ships there.
The issue of enough work to go around is no doubt complicated by the number of yards/block suppliers who are all trying to get their little bit of meat off the bone, is it also time to rationalise the number of yards so that the strongest survive rather than them all slowly starving bit by bit?
We've also seen news in the last few days about shipyards being closed down in the UK for lack of work, maybe we will see that happen here too.
The number of yards here in Australia is no doubt complicated further by each State Government wanting to have facilities in their own states too for all the political reasons associated with that, we've got BAE at Henderson in WA, BAE at Williamstown in Vic, Forgacs at Newcastle NSW and ASC at Techport in SA, yes of course there is also Austal at Henderson in WA too.
If you could take the politics out of it, and that would probably be almost impossible to do, who would be best to invest in for the future to survive and in which locations?
Austal will no doubt survive on it's commercial activities and their patrol boat products for the local and overseas markets. Forgacs as a business seems to have a reasonably diverse portfolio of work outside of shipbuilding and I assume could continue to survive doing that, but would still be used as a block fabricator for the ship assembly yards when that work was available.
So that leaves ASC at Techport, BAE at Henderson and also BAE at the space constrained Williamstown site.
As Volkodav suggested, the Williamstown site could be redeveloped, it would be worth a fortune as new residential or mixed commercial site, no doubt the Unions and the Vic State Government would scream rather loudly about the loss of jobs, but that could be counter balanced by the redevelopment of the site and the employment prospects in construction and ongoing new employment opportunities on that site.
That's not to say that BAE couldn't still be involved in block construction in Vic (as I'm sure the state government and unions would want it to do), be it on part of the existing site or a greenfield site specifically for block work located on Port Phillip Bay somewhere, but would it be worth it? Is that still spreading block work too thinly for the industry as a whole?
So that leaves Techport and Henderson as the nations Naval ship consolidation yards, both sites could also perform block work and if necessary block work would also go to Forgacs and BAE in Vic if it was decided that it was worth having a block construction facility in Melbourne.
Anyway, just my opinion, I just can't see that all can survive in the longer term, so maybe it's better to do some consolidation now for the future benefit and sustainment of Naval shipbuilding in this country as a whole.
