Anchoring Shell’s Deep-Water Oil Platform in the South China Sea
The highly-skilled Shell mooring team anchors a deep-water oil platform to mooring lines on the sea bed using a high-tech ROV submersible and cranes located on the platform. The operation requires high-tech equipment and a highly skilled team in order to make the platform safe from tropical storms.

In a joint venture between Shell and Petronas, it will tap into 19 pre-drilled deep water oil wells with a production capacity of 150,000 barrels of oil each day. Right now, the platform is hooked up to three mooring lines, and held in position by huge tugs.

[Narration]
From construction vessel the Sapura 3000, Paal’s team will use remotely-operated vehicles, or ROVs, to find the fourth mooring line on the sea floor. They’ll haul it towards the surface with heavy-duty cranes.
[Paal Dinnesen]
Okay, you want to grab it and give it a shock.
[Video footage]
Paal in front of nine monitors displaying video footage and various other data. Narrow shot of Paal working.
[Narration]
It’s Paal’s job to ensure the operation runs smoothly.

[Paal Dinneson]
I’m a coordinator, you might say. Four meters aft and four meters upward of the sheet. Cheers, bro.

[Kim Lendrum]
Okay, you’re happy with your cameras?

[Kim Lendrum]
This T4 arm we’ve named “The Beast” because it is so powerful and it does so many wonderful things for us down below.
[Narration]
At a cost of USD $6 million, the ROV can withstand extreme conditions.
[Kim Lendrum]
Well, these ROVs are depth-rated to 3,000 meters, so there’s some pressure there as well as very low temperatures, and that’s what they liked. They always say that a happy ROV is a wet ROV.
[Background music plays]
Intense, suspenseful music.
[Video footage]
ROV being lowered into water from construction ship. Spinning cable mechanism. Water breaking and bubbling. ROV being lowered in.
[Narration]
The ROV begins a descent that will take 22 minutes. The seabed is 1,200 meters deep.

Paal Dinnesen speaking to camera. Submersible disappearing under water surface. Man staring at computer screen intently.
[Paal Dinnesen]
Before it was just mind-bogglingly out of our reach, and of course the engineering and the technical competency is getting better and better, so we’re actually managing to go to those places we never could before.
[Video footage]
Bright lights underwater. Monitors displaying footage and data. Kim monitoring monitors. Kim’s hand moving a joystick with console in the background.
[Narration]
The mooring line that they’re looking for has been lying on the seabed for two years. Kim takes up the ROV controls while Paal directs from the bridge.

[Paal Dinnesen]
Slow down to 0.15.

Kim Lendrum operating joystick. Underwater footage with debris floating by camera.
[Kim Lendrum]
Do you see the buoy? Have you got a visual there, Paal?
[Paal Dinnesen]
Negative. Two meters left.
[Kim Lendrum]
I can see nothing.
[Video footage]
Kim Lendrum speaking to camera in profile.
[Kim Lendrum]
When the ROVs are thrusting around down there, you kick up a lot of the seabed and that obviously disturbs your visibility, which makes it a little bit more of a challenge trying to hook things up and locate their positions.
[Video footage]
Kim operating ROV controls. Underwater footage of bright lights. Kim speaking to camera while facing monitors. Paal Dinnesen speaking into microphone. Alternating shots of Paul and Kim speaking to each other via radio while looking at monitors. Underwater footage of view from ROV cameras.
[Narration]
Kim gets the ROV to hover mid-sea while they wait for the silt to clear.
[Kim Lendrum]
You can’t really see, you know, and the shift supervisor wants everything done as soon as.
[Paal Dinnesen]
We’ve only got about, what, 45 minutes or something.
[Kim Lendrum]
He’s just got to wait for us to get out visibility and then we can move and do things properly.
[Narration]
Kim searches for a buoy that marks the end of the 2 km line.
[Paal Dinnesen]
Is that one coming into view there?
[Kim Lendrum]
Yes, I think I see the chain there, Paal.
[Narration]
The mooring line looms into view.
[Video footage]
Paul Dinnesen at his desk using a small green chain to explain how the crane hooks onto the mooring line. He points to two chain links which are two links apart, then says the hook will come and hook into the link between them.
[Paal Dinnesen]
What we do is we go down with a crane with a spreader bar on, and we hook into a link here and a link here. Then we take up and hold the link like this from the end, and then we come down with our special-built hook that comes in underneath, and then we link up this, and then it’s hanging here. Then, we take the crane up.

There’s a communication problem with the ROV.
[Video footage]
Two monitors displaying text “Waiting for network.” Man standing with hands on hips. ROV cable protruding from sea surface. Worker operating computer console. Workers operating various consoles. Paal in his chair speaking directly to camera.
[Paal Dinnesen]
They just lost total communication. I mean, they lost telephonics, power, cameras, feeds, everything. Ping.
[Video footage]
Various shots of workers looking frustrated. Wide shot of construction ship with crane connected to submerged ROV. Underwater shot with swimming fish and ROV. ROV emerging from water. Wide shot of platform and tugboats from sea surface. Paal Dinnesen speaking to camera.
[Narration]
The whole operation grinds to a halt. Until the problem is fixed, nothing can happen. The only thing to do is to bring the ROV up and fix it. In an operation this big, delay becomes costly.
[Paal Dinnesen]
Is it $500 or maybe $1,000 a minute? I’m not sure, but it’s 24/7. It’s a lot of money.
[Video footage]
Worker removing a grate from ROV. Worker repairing ROV interior. Kim Lendrum working on ROV.
[Kim Lendrum]
We just lost telemetry, lost power on it, so it turned out to be the SIM module.
[Narration]
They replace a cable they think caused the problem.
[Kim Lendrum]
We can do a telemetry test. Fire it up.
[Video footage]

After an hour’s delay, Paal gets his underwater eyes back and begins the complex business of hooking onto the mooring line below.
[Paal Dinnesen]
Okay, just for info, that’s us picking up the line.
[Narration]
Paal uses the position of the boat.
[Paal Dinnesen]
Starboard 2 meters please.
[Unidentified male speaker]
2 meters starboard.

The cranes…
[Paal Dinnesen]
Come down 1 meter on the crane, easy, easy.
[Narration]
And the ROVs to conduct this millimeter-perfect operation over a kilometer under the surface.
[Paal Dinnesen]
Okay, Rudy, come up four meters.
[Rudy]
Four meters.
[Paul Dinnesen]
There’s actually a time delay because of the water depth, so when you do move it, it’s a couple of minutes later that things move on the seabed. Okay, Rudy, bring it in a bit faster.
[Narrator]
Paal tries to manoeuvre the giant hook under the chain, but there’s a hitch.
[Video footage]
Hook moving towards chain. Close-up of big rusty chain covered in sand. Paal in front of monitors. Footage of hook connected to chain. Kim watching monitors and speaking to camera. Footage of hook being manoeuvred into place.
[Paal Dinnesen]
I think it’s wrong. I has to be rotated 180.
[Kim Lendrum]
Yes, currently the hook is 180 degrees out, so we have to reorientate it, and then when everything’s lined up they’ll come up on the wire and the hook will land in its position on the specific link that it has to be on.
[Background music plays]
Upbeat bongo drum music.
[Paal Dinnesen]
Down, down, down, stop, Rudy. Keep going to your left there please, Paul. A little bit left.
[Kim Lendrum]
That’s good.
[Paal Dinnesen]
Keep going up, Rudy. Keep going up. Keep going up. Keep going up. Stop. Okay, we got it. Brilliant. Well done.
[Kim Lendrum]
There we go.
[Paal Dinnesen]
She’s all yours. Chop, chop.
[Video footage]
Hook latching into chain and pulling up. Kim at his monitors. Video of chain being lifted from seabed.
[Kim Lendrum]
There we go. We can see it coming up.

Crane lifting cable from water. Crane hook in mid-air. Workers stowing chain. Wide shot of platform lit up at night. Paal Dinnesen speaking to camera. Cranes moving in space between Sapura and platform.
[Narration]
Each link weighs 160 kilos. The crew temporarily stow it on the Sapura. They need to join it to a short chain that’s attached to the platform, but while they transfer the platform’s chain onto the Sapura, the two vessels will have to work very close together.
[Paal Dinnesen]
We have to actually go up to 10 to 15 meters away when we transfer, and she is moving, and we will be moving, and our cranes are moving, and the wires are moving, so that’s quite tricky, and quite exciting.
[Background music plays]
Touching piano music.
