Vesselfinder shows a little less data but you can trust what you see there
MarineTraffic shows more, but also more random rubbish data,
using the free account you have to be able to interpret what's real and what is spurious.
so take your pick,
AOKA MIZU changed her reported Navigational Status from 'Restricted Manoeuvrability' to 'Moored' at:
Time: 2019-03-19 07:43 UTC
Position: 60.17983, -3.870167
Speed/Course: 0.6 knots / 14°
No drilling, that's done.
There are pumps in each of the two wells.

Drill down [sic] from 'Assets'
AK, I won't decline a nit-picking war because I'm unable to fight my corner, rather because I have more respect for the rest of the board. love.
Ignore the "US" part of the destination "Warwick US".
That's just the result of a port lookup on the AIS system, as Hurricane's Warwick field doesn't exist on the system, but the port in Rhode Island does.
The Havila J & V are nothing to do with the hookup.
They're making their way to Warwick, to prelay moorings for Spirit Energy's first rig.
Nor Solan has been no closer than 10km to our buoy, and is 4km from the proposed Lincoln well, so nothing to see here.
JoeSoap:
Given your theories in your post of 11:21, I'd be interested in your thoughts on the following...
Why does the buoy sit at equilibrium 20m down?
What is the influence of the risers and moorings on the total system buoyancy as the buoy is lifted?
ie what happens to the force on the rope as the buoy is raised from the -20m position?
What is the height of the water column inside the turret before the buoy is hooked up?
and how far above the hull bottom of the ship does the top of the buoy protrude into the turret?
A good rule of thumb when the AIS positions are not received regularly every 3 minutes...
Ignore single outlying positions, (such as the one at 11:44).
Especially if the heading is shown as zero degrees.
That shows that some of the data is either missing or corrupt, as was often seen in Dubai when the AM often went ashore.
you're right, it did update. AM is now less than 100m from the buoy,
VHF isn't so good this morning...
only 5 AIS data points received in the last 2 hours when the AM must have transmitted 40 times (every 3 mins)
To see how good or bad the VHF signal is visually, go to the Marinetraffic vessel details, and the Vessel Timeline chart at bottom right. Then zoom in to a 2 hour period or smaller. (zoomed further out you don't get the points plotted) then look at the difference between the periods 03:00-04:00 (good), and 06:00-07:00 (bad) this morning.
looking at the hourly report from the nearby weather buoy, the trend is still going down, conditions today will be calmer than yesterday.

The Shetland Cliff Cam also looks good
(but do remember this one looks east, and is sheltered from the prevailing westerlies)

Fingers, toes and everything else crossed for today...
If you haven't seen them before then I can recommend you look at the Hurricane website, those photos and much more good info on there.

erratum: "the GPS position hotspot identified on Marinetraffic is a few metres FORWARD of of the turret."
(a result of too much editing to make it readable!)
Rangers1: correct.
The GPS antenna on the AM is mounted above the bridge.
Our point of interest, the turret, is immediately behind the bridge, so the GPS position hotspot identified on Marinetraffic is a few metres astern of of the turret.
But (isn't there often a"but"?), Marinetraffic doesn't always plot the hotspot in the correct position!
The default position of the hotspot on the vessel outline its the centre of the stern.
There's a manually set parameter which gives the offset of the hotspot on the vessel outline as a distance forward and to the port or starboard of the stern centre. That data is transmitted less frequently than the position data (as it doesn't tend to change). What can happen, is if the position data is received, but the offset data isn't (which often happens at Lancaster) then the hotspot is shown in the default [incorrect] position. If you zoom right in and get the large vessel outline, you can see which of the two cases is being shown at any particular time.
So, sometimes the GPS hotspot displayed is a little forward of the turret position, sometimes it's right back at the stern of the ship.
slipanchor, "Maybe they didn't want to give shipwatchers an advantage over the market"
Do you mean that all those vessels west of Shetland that are slipping in and out of VHF range from the base station on Shetland are playing with the minor shareholders of all their respective associated companies? I'm surprised any vessel in around the coast is using AIS, I mean such a useful tool in dangerous conditions like driving snow, why use it when you can play silly buggers with people who only might be watching the internet in their underpants.
I don't suppose you could explain how temperature inversions changing the refractive index of air affects VHF propagation, range, ground footprint and quality of signal for us could you?
And how the constantly changing VHF working range is significant for AIS data getting from ship to shore?
When you're in a hole, stop digging.
Or would you like me to fetch you a bigger shovel?
Slippanchor: "she is displaying an old position looks as though the AIS has been turned on, to give the position displayed, then turned it off, maybe playing games with us."
Complete fabrication.
Commercial oil industry vessels do not switch off maritime safety equipment to play games with idiots on internet discussion boards.
PS. Oh yes, we do have a company valued at £1 billion that isn't currently making any money.
What was your point?
Who is this "we" of whom thou speak?
How do you know anything about what is already priced in, or not?
The anchor symbol is an AIS 'port' marker.
It's used as a marker on the map to allow vessels to set that position as a destination for navigation.
It'll be useful for the tankers that will come to offload later.
Glen Lyon, our closest FPSO neighbour also has one.
