Interview with Kent Stingl
BC-10 Project Manager
[Kent Stingl]
My name is Kent Stingl and I’m the BC-10 Project Manager.

Kent Stingl, BC-10 Project Manager, Shell Brasil
[Kent Stingl]
I’ve been associated with the project since 2004.
[Video footage]
Helicopter fly-around of the Espirito Santo vessel at sea. There are two smaller ships close-by.
[Kent Stingl]
BC-10 is about 120 kilometers southeast of the city of Vitoria. It’s in the northern Campos basin. It’s a relatively new area, not only for Shell but for Petrobras as well.
[Video footage]
We’re approaching the Espirito Santo vessel by helicopter. We can see the helideck aboard the vessel as the helicopter prepares to land.
[Kent Stingl]
The water depth is about 2,000 meters at its deepest at the Abalone Field. It’s ultra-deep water. We’ve been deeper, but each time it comes with a new challenge. It’s a relatively benign area, in terms of there’s no hurricanes or monsoons, but there is a constant swell in that area and that constant swell is something that we had to incorporate into the design of the FPSO and into the risers and umbilical’s to be able to overcome.

Animation of Shell employees, dressed in red with white helmets, walking aboard the vessel where we can see the infrastructure of pipes and risers. Then back to interview with Kent Stingl.
[Kent Stingl]
BC-10 is a technically very challenging project. It’s the first one that we’ve actually taken from the exploration phase all the way to the production phase in Brazil. It has a variety of different reservoir properties, small to medium-size reservoirs, so not one big accumulation.

[Kent Stingl]
We need to tie those together and make it an economic proposition.
[Video footage]
A Shell employee is standing on the deck of the Espirito Santo with his back towards the camera. He is wearing a red jacket with the Shell logo and the words Shell Brasil E&P written across it. Turning to the side, we get a glimpse of a ship approaching the Espirito Santo.
[Kent Stingl]
We used an FPSO solution because we’re 120 kilometers offshore Brazil and we have a very heavy oil regime. So we have heavy oil and it has lots of minerals in it, so we needed to be able to capture the hydrocarbons, store them, and then be able to transfer those to a ship where a tanker can come by and then take those and sell them at a refinery that can actually process those heavy oils.

[Kent Stingl]
The FPSO is actually a 1975 vintage Japanese crude carrier that spent the first 20 years of its life carrying crude around the world, and then it actually was an FSO, which is a floating storage and offloading vessel, offshore in Nigeria. And when we got it, it was in relatively bad shape so we had to convert that vessel.
[Video footage]
Time-lapse of the Espirito Santo being approached by various floating cranes and other machinery to commence the restoration work.
[Kent Stingl]
We had to replace all the tanks and for collision resistance, since most of the new vessels are actually double haul, we decided to put what we call sponsons on them, on the sides of it.
[Video footage]
Time-lapse of sponsons and steel being put on the sides of the vessel. Further restoration work is done to the vessel in a port.
[Kent Stingl]
So on the sides of the vessel we have 13 sections of impact resistant steel that go on the side which essentially duplicate what a double-haul vessel looks like nowadays.
[Video footage]
The Espirito Santo leaves the port.
[Kent Stingl]
This is one of the deepest FPSOs in terms of water depth anywhere in the world. At 1,780 meters it’s an extremely deep water development.
[Animated sequence]
Animation of the subsea infrastructure. We can see a floating platform at sea-level with various umbilical’s reaching down where they are fastened to the seabed.
[Kent Stingl]
On the subsea infrastructure, again, we had to combine the subsea pumping and artificial lift system.
[Animated sequence]
Development of the subsea infrastructure. We can see various constructions such as reservoirs and pumps being added to the site which are all interconnected.
[Kent Stingl]
That’s an absolute first. It’s the first full field development where we’re using subsea separation and artificial lift to optimize the production and ultimate recovery from the reservoirs.
[Animated sequence]
360 degree shot of the entire subsea system. Pan up following the umbilical’s up to the sea surface where they enter the vessel.
[Kent Stingl]
The subsea system is all-around flow assurance. How can we produce the hydrocarbons and how can we keep them flowing without them freezing, without having wax precipitation problems, and how can we boost the pressure? So we need to boost what nature normally offers us. So instead of having an aquifer support that pushes the oil through the rock, we need to be able to pump that hydrocarbons up to the surface.
[Animated sequence]
Underwater shot of the subsea system. Zoom in on the pumps, in white, showing the flow of oil.
[Kent Stingl]
But the pumps themselves are not very efficient when you have gas fractions in the oil and in the water, so you want to be able to separate the liquids from the gas.
[Animated sequence]
Sequence showing the gas being separated from the liquids. The flow of gas is illustrated in green, and the oil in red. We can see the two flowing through the pumps and being separated.
[Kent Stingl]
And then you could have the gas free flow back naturally up to the FPSO and then you can pump just the liquids themselves, and that’s the most efficient use of the pumps that we have.
[Animated sequence]
Underwater shot showing the liquids, in red, and the gas, in green, being pushed through the pumps all around the subsea system.

Interview with Kent Stingl.
[Kent Stingl]
Well, we had up to 5,000 people working on the project on any given day during the execution phase, primarily in Singapore where we had around 3,000 people at our peak fabricating the top sides, installing the top sides, and commissioning all of the hull systems. So a huge team, a global team. We had people in Brazil, we had people all over the world working on the project, so one of the big challenges was trying to coordinate all these activities across a 24-hour time zone.
In the United States, we manufactured the electrical submersible pumps and we fabricated the umbilical’s. In Europe, we fabricated the tubes for the umbilical’s themselves. In Colombia, we fabricated the copper cores that went inside the umbilical’s. We actually moved our team, our FPSO team, from the United States to Monaco where they stayed for one year to do the detailed design work, and then took that same team and moved them over to Singapore where they were there for the fabrication and commissioning of the FPSO themselves.
The execution of BC-10 on time and on budget really proves to the world and everyone in Brazil that we should be, or we can be, the preferred operator.
