Notes on the Live video links from the ROV's monitoring the damaged riser. ver-VII.a

Please be aware, these are live streams and may freeze or be unavailable from time to time

Just thought this may be a useful way of viewing all ROV's working, on one page. (Remote Operated Vehicle.)
Let me know if this was useful, and advise of any errors and omissions. Thank you.

Macondo is the name of the fictional town in the novel
- "One Hundred Years of Solitude" by Nobel Prize-winning Colombian novelist Gabriel Garcia Marquez.
The Field was developed by SubSea IQ a Texas (US) based company
- They are OffShore Field Developers
- A huge list of their worldwide offshore projects is Here; 17 pages of offshore wells worldwide
- Their Macondo Project Detail is here: Full Details
The Rig is owned by TransOcean (CH) (Swiss) Sym: RIG
- It is an Offshore drilling contractor
The Blow-Out Preventor (500tonnes) was supplied by Cameron International Corp (US), Sym: CAM
- who make Valves and Blow-Out Preventors.
The Cement-in contract is by Halliburton (US). Sym: HAL
- They are a Driller-Completer-Producer (Cements in the well-head)
M I Swaco Supplied the Mud Drilling.
- They provide all the oil-, water- and synthetic-base drilling fluids and muds and additives and dispersants.

The WORLD consumes 85 million barrels of oil each and every day. (1 barrel = 42 gallons=159litres)
The Macondo DeepWater well is estimated to contain at least One Trillion Barrels of oil. (enough to last the world 50 years)
5% of the Worlds population (US) consumes 80% of the worlds resources. China is very close behind in it's consumption rate.
Definition of an Oil Barrel
All the mechanical equipment and pipe work is leased (rented) to BP Anadarko Moex (UK-US-JP) at approx. $USD500,000 per day.
BP, Sym: BP is the 4th largest company in the World. (note: the 8 largest companies in the world are NOT American!)
Stock Price: sym: APC Anadarko.
Stock Price: sym: BP

NOTE:

BP(65%) / Anadarko(25% / MOEX(10%) combined, owns the WELL, & what is in it.
- i.e.: there is a big 'cavern' 23,000 ft below the ocean floor,
- the oil in this cavern is 'owned' by BP/Anadarko/MOEX (Mitsui Japan)
- .....by virtue of an Oil & Mining Claim;
- It is estimated this 'cavern' contains at least One Trillion Barrels of oil. (enought to last the world 50 years)
TransOcean owns the equipment. The drilling rig and pipe work.
- Which includes the pipe thru the rock, up to the surface of the sea, on the Macondo Property
- .....and leases/rents it to BP.

The ROVs are from the Surface Vessels:

Ship: Enterprise: ............
- R1 & R2. One or both may be monitoring the 'cap'.
Vessel: Q4000 ............
- Owned by CalDive, operated by Helix Solutions (Canyon)
- PDF info file
Vessel: Helix-Producer MV Karl Carstens ............
- Owned by Kommandor LLC,Denmark operated by Helix Solutions (Canyon)
- Picture and Details of Helix-Producer
- The HPI will be part of BP's containment plan to capture and process oil and gas from the Macondo well, offloading to a tanker.
  The HPI will join two other contracting services vessels owned by Helix, the Express and Q4000, in supporting BP on the Deepwater Horizon spill response and containment operations.
  HPI is capable of producing up to 45,000 barrels of oil per day.
- This ship is a 'Dynamically Postioned' production unit capable of staying on station during a hurricane
Ship: Viking Poseidon: ............
- R1 & R2 various projects.
- Operated by 'Veolia ES Special Services' in USA
Ship: Skandi Neptune: ............
- R1 & R2 are also monitoring the 'cap'. (Skandi Neptune is their Surface Ship)
Ship: Canyon Offshore: ............
- MVs: Seacor & Acclaim & Triton
- rovs are sampling the ocean bottom or working at the base of the BOP
Ship: Ocean Intervention III: ............
Ship: Boa Sub-C Boa Deep-C: ............
- Built for Chevron's Gulf Operations. Boa vessel list
- R1 & R2 may be back aboard for grease-lube-&-oil-change (Boa Sub-C is their mother ship)
Others may be back on board their respective ship/s.

There are some 18-20 ROV's in action. (I am showing only 14 rov's. on the Main Screen.)

Some are acting as winches or platforms and have no cameras,
- only echo-locators & lights &/or Spatial Reference Navigational-Locator devices.
Some ROV's come out of a 'cage' which has:
- a winch & cable back to the surface,
- a fiber optic cable back to the surface ship, 38mm diam.
- a fiber-optic & tether cable to the rov,
- and echo-locators & lights;
The Cage looks like a box-shaped pipe scaffold with lights

Note: Undersea cables across the Atlantic, Pacific, Tasman, North Sea
are serviced by these type of Remote Operated Vessels

Keep in mind:

The DEPTH; (1.53km below sea-level) = (5,020 feet) = (0.95 of a mile)
The WATER PRESSURE; (153bar) = (2,220 psi) = (One ton per square inch!) = (160 tons per sq ft)
and that the ROV's hands are NOT human hands.
And the ROV's have echo-locators (Like a Bat, the ROV uses echo-locators better than the Video Cameras)

If a feed is blank, the ROV is probably 'parked' because it is not needed,
- or the operator is doing something else,
  - i.e: Bathroom break; Looking at Drawings;
  - in discussion with other operators/engineers,
  - or using another camera, or the Echo-Locators.
or the ROV is up on deck for a 'Grease, Lube & Oil Change'
If the image is stationary, the ROV is 'Monitoring/Observing'

The ROV operators are all highly skilled Maintenance Engineers. Most have Engineering Degrees and hands on Fitter/Welder Maintenance experience, before becoming ROV operators. **

Observe on the rov's Heads-Up-Display (HUD) in the feeds:

The Depth Gauge:
- approx: 1.53km (5,020 ft) 'below' sea-level; and compare:
The Altimeter:
- it is a measure of Distance above the Sea floor.
- it may vary from 5ft to 70ft to 90ft etc. 'above' the sea floor.(1.5 to 28 metres)
- you may see the BOA ROV's working below the BOP on the base of the pipe (zero altitude)
- The Water pressure at this depth is 153 bar or 2,220 psi. i.e. approx. One Ton per square inch!
  ..... (so the pressure of gas coming out of the pipe is at least 3.5 to 5 times greater coming up from 23,000 ft below the sea bottom.)
- The hi-tensile steel pipe above the BlowOutPreventer is 54 centimetres in diameter ( 21 inches) and has a wall thickness of 2.5 cm (one inch)
- The BlowOut preventer is approx 30 metres high (approx 98-100ft).
Total height of the BOP stack is approx. 90 ft,
- and hence rises over 100 ft (29 metres) above the sea floor to the cut at the top of the BOP.
The Taskbar
- it shows a brief description of what the ROV is working on.
- it may vary from 'Dispersant Ops', Monitor, Remove Choke from Manifold, etc.

Why the perceived 'leakage' from the 'cap' on top of the BOP? ...

The Bernoulli Principle: en.wikipedia.org/wiki/Bernoulli%27s_principle
The Venturi Effect: en.wikipedia.org/wiki/Venturi_effect

If some doesn't push out under the 'cap', sea-water will be dragged in and move up with the oil coming out of the BOP and accelerate up the pipe, and freeze solid. Thereby blocking the pipe to the surface collection ship Enterprise.
