Seen loaded on deck of the Dockwise HLV "SWAN" (ex Dyvi Swan) for transport from Sydney NSW to Portsmouth in the UK on 28 October, 2002.
The USS Cole was loaded on the Blue Marlin in 2000:
As can be seen the Blue Marlin deck is long enough to accommodate the USS Cole, but she is still loaded with the bow hanging over the sides.
This was to protect the Asdic dome which is sticking down below baseline. The alternative would have been to build up cribbing to lift the vessel high enough above deck to clear, which would have been costly, time consuming and would have made the lifting of the cargo out of the water more difficult.
