You want to hear the names of that two vessels?
Well, the AHTS "Fairmount ........." can be:
"Summit" http://www.fairmount.nl/page.php?idObject=413
"Alpine" http://www.fairmount.nl/page.php?idObject=431
"Glacier" http://www.fairmount.nl/page.php?idObject=432
"Expedition" http://www.fairmount.nl/page.php?idObject=433
They all are the sister ships of "Fairmount Sherpa" & has the same ship particulars.
About that heavy load semisubmersible barge, it can be:
"Fairmount Fjell" http://www.shipspotting.com/modules/myalbum/photo.php?lid=156555
"Fairmount Fjord" http://www.shipspotting.com/modules/myalbum/photo.php?lid=139000
They looks in the same way
About the current question - I haven't found any similar to that vessel on fairmount.nl site. Must be a some kind of a project?
