I am guessing the bids on the Table were not what ALU was looking for.  I also am guessing that this division is a money loser, as most of its business nowadays is probably repair and replace under sea fiber optic, Hence the stated desire back in July 2014 to add oil and gas exploration, of course we know what happened to oil and gas since.  Unlucky timing.

That said, I am sure the unit will eventually be sold when the oil and gas business mends some, as it is not a core business unit.
