That blue ship is a Norfolk Line Ro-Ro.
Landguard extension will primarily be given Maersk priority afaik.
I doubt that Hutchinson would have let Maersk take over their port, even if it's only partial.
Currently there are only some dinky cranes on Landguard, but an order for 12 cranes (I think) has been made and they will be bigger than the biggest one we currently have over at Trinity.
So it should easily cope with the likes of the Emma Maersk class vessels.
I did work on the Emma Maersk on her maiden call to Felixstowe, impressive to say the least, but 23 wide is alot of lashing!
