Sinking Ship Simulator: The Royal Navy’s Damage Repair Instructional Unit

Sinking Ship Simulator: The Royal Navy’s Damage Repair Instructional Unit

STEVE RAY: Behind me is the DRIU,
Damage Repair Instructional Unit basically a big metal box
which we flood It’s a mockup ship, so the
internal layout resembles pretty much what you’d see on the majority
of Royal Navy ships that are in the fleet today. Primarily used for practical
damage control training. TOM SCOTT: “This is serious kit.
I am… I am really… “We’re going to have to go in,
repair some holes in the side… “and I’m a little bit terrified.” MATT GRAY:
“It’s just normal temperature water. “We’re going to freeze
when we get in there.” STEVE RAY: We’ve got four sections
of the ship, split over three decks. We’ve got complete control over
water levels, smoke and lighting levels, We can control pipe damage,
deck and bulkhead splits, We can roll the unit up to 15°
either side of upright. at a variety of different speeds
to simulate different sea states. So today the beginners are going
to be getting just 5° of roll which will seem like a lot to them. Instructional staff will be getting
the full 15°, to make it harder. [SHOUTING] MATT: Bloody hell! [INDISTINCT ANNOUNCEMENT] TOM: The very first thing,
the 120psi breach. and it’s pointed at us, and the
very first thing we have to do… MATT: You could feel the pressure
from two metres away, just from the air it was chucking at you,
never mind the water. MELINDA SECKINGTON:
I didn’t quite realise how much you’d feel it when I went to grab the
wedge bag. [WATER SPRAYING] STEVE RAY: First hit, Zulu One,
will consist of a small deck split, and a large multi-split
in the ship’s side. First stage leak-stopping on both of those
will be softwood wedges. – Ready?
– Ready! TOM: Getting pushed under…
who got the breach underneath? PAUL CURRY: I got that.
TOM: That was you? ‘Cos I tried that, and I just
could not find the breach. PAUL: No. No. It was really tricky.
And the first time I went down, I couldn’t find it either. I knew it was
between your two shoes, could not for the life of me
get the wedge in, and all the time I was trying to
be buoyant as possible, which is not useful(!) STEVE RAY: Anyone in the Royal Navy
that is going to serve on a ship will have to complete training
here on the DRIU. Intent being, to be able to confidently
enter a flooded compartment, carry out first-aid leak stopping, be familiar with the equipment
that they’re going to be using, effect permanent repairs and
remove water from the compartment. PAUL: The multi-split. TOM: You were up there for a long time, Matt.
You got a lot in there. MATT: Lots of hammering,
but as the water’s filling up, you can’t find where the holes are,
because the water goes above where they are. TOM: You were up there for… as well? MEL: I was pushing.
MATT: Yeah. TOM: You had to take all the weight
of Matt pushing against you. MATT: Did you see the bit where my foot
started flailing off to the side? I couldn’t bring it back
under the pressure! STEVE RAY: The head of pressure
is similar to what you would see a couple of decks
below the waterline. So the water pressures, we believe
to be realistic. Some of the pipe damage,
we do pump the water in, to simulate a high-pressure seawater breach
or fluid system pipe damage. TOM: Wedge! PAUL: Props to Tom for actually
splitting a wedge in the heat of the moment. MATT: I completely forgot about that!
“But it won’t fit!” PAUL: That was intense. TOM: “Oh yeah, we can do that!” [SIREN] STEVE RAY: Second hit, you’re going
to see a 3-inch rocket hole. It’s going to be in a particularly
awkward position behind a locker. So we’re looking to see
somebody inside the locker, possibly with teammates
backing them up, while they look to get
wedges into that hole. ANNOUNCEMENT:
Missile launch detected, brace, brace, brace. [SHOUTS AND RUSHING WATER] ANNONUCEMENT:
Stand to, carry out blanket search. STEVE RAY: We’ve got a safety number
on the gantry watching the exercise, and controlling the exercise.
They’ve got complete control of the water level within the compartment,
so they can make it higher if you’re doing well,
to make it harder for you, or if they’re feeling kind,
they can drop the water level. They can also remove all the water very quickly
in the event of an emergency. They’ve got direct communications
to the unit driver, who’s in the driver’s cab. The driver can turn on and off incidents, they have control of
all lighting and smoke levels, how much the unit is rolling. It’s clean water similar to a swimming pool,
so we chlorinate it, it’s stored in a sump
directly below the unit. And then we pump it up to the header tank
prior to an exercise starting. TOM: The cupboard! [SPUTTERS]
We all tried it! I’ve still got water in my ear,
‘cos… just full force. MATT: I managed to get my head in,
and sort of round so then the water’s
all here and missing my face. But then you can’t see anything! TOM: The wedges kept diverting
left and right. PAUL: I was inhaling water
most of the time, so even though I had the wedges
in the right place, I got exploded back out of the cupboard
because I forgot to breathe. TOM: But then you got it! PAUL: Yeah! Eventually. TOM: What did you do to make it work? PAUL: Wedges on the left hand side
of the incident and then push them towards the stream. TOM: And it was that kind of
arrowhead formation, so you put two in,
then one in the middle, hammer it in
and it all widens out? PAUL: That’s it. And because the wedges
were given to me in that formation and then a hammer followed…
TOM: Well done Mel! PAUL: It worked! STEVE: We’re looking for a
second-stage build on the deck split, which will just be a vertical shore, utilising a rubber, steel and timber
sandwich pack on the deck. The importance of
damage control training. Ultimately: flooded compartments
will remove buoyancy and stability from the ship, too many flooded compartments,
the ship could be lost. Of equal importance, there’s going to be
equipment in each compartment, which directly affects the
fighting effectiveness of the ship. Wartime, we need to recover real estate
to allow us to fight the external battle. And peacetime, we’re looking to maintain
enough buoyancy and stability to keep the ship afloat. TOM: Controlled conditions, in a simulator, it took four of us five attempts to close
a breach at the back of a locker. The professionals are in there now, they’re going to do that and beyond
in five minutes. It took us twenty! And that was on the easiest levels. [SHOUTING] TOM: I’ve seen Royal Navy trainees in there
when I did the recce for this, and the trainees…
it’s the working together. It’s knowing that there is going to be…
‘cos we were chaotic! There was teamwork in there… PAUL: We left an entire
hammer behind at one point. TOM: Did we? [LAUGHTER] MATT: But we did manage to do it. PAUL: They trusted us with hammers…
and we prevailed! [LAUGHTER] [Translating these subtitles? Add your name here!]

  1. They should definitely use saltwater instead of freshwater for this exercise imo. I get that its rougher on the hardware but the difference between saltwater and freshwater in these kinds of situations is substantial.

  2. so if ur every one else u gotta get a proper job if your in the navy u can muck around playing crystal maze all day

  3. Trowback memories thats I was in the RMNAVYS is fun when do workup training to completed our task tq admin cause flashback my memories

  4. Been in a dredger hull with a 1m crack, would open up with the ladder down, was down there for fair while filming it, was good to take a break and watch the waterfall, very relaxing.
