Prelude Takes Shape – Beneath the Sea Accessibility Transcript
Vision: Prelude FLNG Flare Tower
Music: Sound of Shell.
Voice over:
Last year we watched as Prelude took shape in the bustling shipyards of South Korea.
Vision: Graphic Locator
Music: Sound of Shell.
Voice over: Now far off the coast of Western Australia, another vital aspect of this world first project is beginning to emerge.
Vision: Graphics Subsea
Music: Sound of Shell.
Voice over: Deep beneath the sea, Prelude is connected to a critical network made up of Christmas trees, manifolds and flow lines, all connected to giant anchor piles. The role of this network is to control the flow of gas.
Vision: Shington Widjaja, Subsea Hardware Engineer
Shington Widjaja: ”This is the last manifold before the gas gets into the FLNG. And what this is, is a safety device. If there are any issues with the subsea, the valves can close here and it prevents hydrocarbons from going into the FLNG.”
Vision: Manifolds, Xmas trees, anchor piles ocean
Voice over: With construction of the systems now complete, the job of the subsea team was installation.. In one of the loneliest places on the planet
Vision: Paul Hoban, Subsea Project Manager
Paul Hoban: ”I’ve never worked anywhere as remote as Prelude. There’s hundreds of kilometres in every direction and we’re working 250 metres below the surface. In order to do this job, we needed 250 people and six vessels mobilised from all over the world.”
Vision: Graphic Title, Henderson Western Australia – footage of anchor pile deployment
Voice over: Like here in Henderson, Western Australia, where the giant anchor piles were manufactured then loaded out for deployment.
Vision: Eric Gerbeding, Upstream Projects manager
Eric Gerbeding: ” We’ve got a lot of activities going on. You’ve had the design, the construction and the movement. It’s really critical that it’s planned well and it’s safely executed.”
Vision: Graphic Title, Karratha, Western Australia
Voice over: And in Karratha we’re the four Christmas trees were loaded on board the North Sea Atlantic.
Vision: Nigel Goh, Graduate Discipline Engineer
Shington Widjaja: ”We’re mobilising right now, it’s been a really good controlled lift so far. We’ve got one tree down, the second tree is coming on right now, we’ve got the second tree coming on right now. We’ve got two more to go, but once that’s on, we’re basically good to go for the campaign.”
Vision: Timelapse mobilisation
Voice over: In total 6 mobilisations across three different countries involving 10 vessels were required, before everything was finally in place.
Vision: Kevin Lau, Prelude xmas tree lead
Shington Widjaja: ” Basically after two and half years of design and testing of all the trees onshore, we’re going to go offshore with these four trees and put them on actual well heads now and get them wet.”
Vision: Aerial footage North Sea Atlantic
Voice over: On the 8th February, the construction vessel the North Sea Atlantic set sail.
Her destination, the prelude gas field, a three day journey.
Vision: Paul Hoban, Subsea Project Manager
Paul Hoban: ” Working at sea and especially on the ocean floor, is like working no other place on the planet. Prelude is particularly challenging, because you have very strong currents both on the surface and subsea. And quite often you cannot see anything on the sea bed.”
Vision: Footage Prelude gas field installation begins
Voice over: The moment of truth had arrived for the subsea team. Installation began with an anchor pile.
Vision: Rigger to camera
Rigger: ”Communication is number 1 with us really, because if our comms fail, things can go wrong pretty quickly”
Vision: Footage of anchor pile installation
Voice over: First the fully loaded barge was brought into position. With everything in place, the riggers stepped on board. And the lift could begin. It’s an operation that required everyone working as a single unit. With the barge now clear, the vessel was steered into position. And the anchor pile was carefully lowered into its new home...
Vision: Shington Widjaja, Subsea Hardware Engineer
Shington Widjaja: ” Hopefully this is the last time we see this for the next 25 years. It goes down to the seabed and it stays there.”
Vision: Shington Footage ROV crew
Voice over: In the water, the operation enters a completely different world. The ROV crews become the eyes and arms.
Vision: RV Operator
Voice over: By the time we get to the seabed we will lower this, because of the weight of the pile, it will sink below the seabed, until it is about 8 metres below the sea bed.
Vision: Monitors showing anchor pile subsea
Voice over: While state of the art technology allows team of surveyors track each movement as the anchor pile descends through 250 metres of water. The result is that even in near zero visibility, the giant structure, can be guided into position, with pinpoint accuracy.
Vision: Kevin Lau, Prelude Xmas Tree Lead
Kevin Lau: ” Yes, we’re happy with that it’s good. One down, three to go.”
Vision: Footage mud mats, xmas tree installation
Voice over: Prelude’s manifolds, xmas trees and anchor piles are now in place. The campaign was completed in 21 days, 8 days ahead of schedule without incident.
Vision: Paul Hoban, Subsea Project Manager
Paul Hoban: ” Quite frankly, this is the best campaign I’ve ever been involved in. It was down to personal responsibility. People both in Shell and our contractor Technip really took ownership of their scope. They innovated when they had to and they delivered a safe, efficient and high quality job. That’s everything you can ask for.
Vision: Shots of Prelude equipment on the bottom of the sea
Voice over: And step by step, Shell’s Prelude FLNG project has moved one step closer to becoming a reality.
