Picture and explanation sent In by reader Tad. Thanks!
Attached is a
pic of a 'proper' anchor handler, a bit over 13,000 hp - with a rig anchor
on the deck, the thing with two points up near the wheel house. This anchor
is a 13 ton embedment anchor, pretty standard size anchor for a large sized
moored rig. You can see the pennant line / work wire running from the winch
house over the deck, again between the shark jaws and towing pins and over
the roller. You'll note this vessel has dual sets of shark jaws and pins -
the port side set are retracted into the deck. This was a case of running
anchors. The anchor to be run would be suspended below the anchor handler's
tail roller, with the vessel heading away from the rig as the rig pays out
anchor wire from the winch. Once in the proper location, the vessel then
lowers the anchor to the sea bed. The next one to be run is sitting on the
deck. The captain is sitting up in the wheelhouse, on his secondary control
center, that row of windows. He's got a backward facing comfy chair with
joysticks and touchscreens to basically control everything from where he
sits.
This picture was taken from the drilling rig, looking down on the vessel as
it came alongside to receive the rig's anchor cable which the deck crew is
in the process of hooking up.

Well, damn, I learn something new every day!

That's why I like coming here; no matter what photo is put up, someone out there has a good explanation of what's going on for those of us that don't have a clue.
