42:03 That bit on there is called a Connecting Rod or Con Rod. There's usually a Piston on the opposite end of a Connecting Rod, so that it rotates a Crankshaft
Done these myself..great explore..we got in through the west enterance (now welded shut) we saw the old green pumps , and the bullet holes in the main entrance sign
That is one massive operation they were doing there, I have never seen anything like it. Those two gentlemen were okay, that was really cool to see thank you brother.
Theres 9 fuel tanks each held 15,000 tons of FFO ( furnace fuel oil) .The last Royal Navy vessel to use FFO was HMS Bristol, now used for training and is moored in Portsmouth.
Brilliant explore, although I've lived near this area all my life, it still amazes me the amount of infrastructure built under Portsdown Hill, the length of those lower tunnels after you went through the pump room, they went on forever & you didn't even go to the far end of one of them! IKS have done this one, but I don't think they went as far as you did! Btw, brilliant aerial footage of the Forts on Portsdown Hill & Surrounding areas I could almost see my house!
check out RAF Rendlesham underground tunnels in the Forrest linking the 2 bases together, and also linking apparently bawdsey / everyone says there isnt any , there is !!!
I live near here and drive along Portsdown hill regularly and i have known about the fuel bunker for years and my grandad said in the 50s-60s he used to go down there with his mates with little to no light and explore them. I have often wondered what they look like and it fascinates me that these are under my feet. Grate video:)
As an adult, I would love to get into Urban Exploration, we done it regularly as kids, but it wasn't called that then, it was just part of an ordinary 1970s 1980s British childhood 😉👍
Your knowledge and information about this place is very impressive, you covered just about everything in the description which was really interesting. Your genuine passion and determination is abundantly clear to me and I’m happy to subscribe and support your channel. 😁💜🌍☮️
You are very lucky not to have fallen through the wooden floor at the base of the construction shaft. Specialist contractors have assessed it as likely to collapse with potentially fatal consequences. This is just one reason why new measures are now in place to prevent further exploration. Vicarious liability means that the owners could be held responsible if a trespasser came to harm.
Not nay saying just constructive comments. But those transformer cores ard not ferrite. Ferrite is that black compressed powder cores used for small switching transformers and inductors. And ring cores for toroidal transformers. Those cores are scillicone steel laminated core. Again ment as constructive not a bitch 👍
Nice .. seen IKS video of this place. When that place was fully functioning with all the pumps and fans and transfomers .. sheesh .. must have been a real unpleasant place to work ... all the loudness of the machines and probably the vibration too which runs through your body and feels really annoying.
Born and raised in portmouth and never been able to find people who know how to get into them as always wanted to explore all the history or the town I was born
At 30:26 watching you trying to explain a halon or co2 fire system as water , those are fire extinguisher gas bottle racks not water under those metal plates are led ingots thet melt if thare is a fire , if this fire system went off and you were in thare you would die due to lack of oxygen
Absolutely brilliant amazing the way you did the drone footage at the beginning with the information. Love seeing the proper old school machines machines. Been watching all you're vids top man fp. When are you going to find the secret tunnels from caerphilly castle going to the mansion on the mountain Matt ?🙂
Your sprinkler system for the transformer’s would be connected to cylinders of halon gas rather than water. You can see the cylinder holders underneath the conduit in the corner.
One funny thing is, first the oil is coming from the ground and going to the factory to make it good and clean, then the oil is going back in to the ground! :)
The fire extinguisher system would have been connected to co2 bottles water and electricity doesn’t mix you can see the bottle shaped brackets that would have held the tanks the room would have been flooded in co2 should a fire have occurred same system we had in the engine rooms of the ships I’ve worked on
@@yonolono8717 go up portsdown hill and investigate like everyone else's guess.. they made a big point of not answering so don't ask, it's up yo you if your interested to source more information and investigate.. its half the fun.. it be boring if it was handed to you on a plate 👊👍
@@yonolono8717 I hate text.. it has no emotion.. I wasn't being funny just helpful and just repeated what they said so sorry for how it came across.. I'm really local are you? I can help you but I don't want to disclose stuff on here really
@@yonolono8717 finding information about these places online can be tricky as they are often still owend by the government/military and have a certain element of secretary to them not just because of what they are but where they are and what they contain etc not to mention the risk of explorers injuring themselves or worse.. by researching I mean don't just ask Google the questions like where is it I'd watch other people's videos and see if they give away any clues either in the video or in the comments and try going on Google earth or maps.. back of portsdown is all fields so look for something somewhere hiding in plain sight maybe? 🙈😉😉😃
I went down much older tunnels with chalk walls and oak doors and a jail? Left of the Forts looking to the hill. I lived in Portchester in the 70s We rode our ponies all around the area and found loads of 'lost' places...the entrance we went in was sloping no steps. Again not saying where...
That entrance you said your not aware off is the north it’s all concreted over it was the only entrance in before it was covered then the new access was made just for your info
Great video guys. I live minutes from here and I know where 4 entrances are and they are sealed and concreted shut. Or at least they was a month ago! When did you guys visit??
@@josh_1503 no mate, other than a generator and a breaker to get through the concrete slabs they have put in front of the 2 main entrance doors and also the middle entrance. The rear entrance is fully concreted now!
@@josh_1503 that’s the north entrance, up until a month or so ago the concrete was only 3/4 way up and you could get over the top. As far as I’m aware, those 4 entrances are the only ways in, but as I said, with the concrete in front of all doors, I can’t see a way in now! Which is a shame, I spent 3 hours down there, so much to see! Best of luck bud
It might be possible to open this up again by hiring a petrol disk cutter that can go though concrete and metal. They are only £16 for a days hire. There was the old rotor bunker in the IOW that was buried for years, then someone got the plans and dug up the entrances again.
Been trying to get in the bunker plus I live portchester my fine fellow Dan and Andy and kyle should come down do some paranormal stuff there it is haunted and bucky.
Enjoying the show of these unseen places. That oil your legging it through could be FFO, most of the surface fleet ran on it. Furnace Fuel Oil, it was heated to allow it to flow and be burnt in furnaces under steam boilers. It would be sprayed under pressure (pressured thru reciprocating pumps)preheated from an exchanger through sprayers at the boiler furnace front, these were known as registers. These sprayers would atomise the fuel oil to allow it to ignite. Spray jets would be cleaned often, shit of a job handling hot spray bodies dripping with what looks like bitumen. Big diesel powered ships still run on this shit, now known as bunker oil. Low level of production required in a refinery to turn from crude to usable product. Ask me how I know, marine grade diesel is the common fuel now used, ships boilers are now a thing of the past. Similar tech is used for nuclear plants for steam propulsion. But the fleet mostly run gas turbines backed up with cruise diesel engines.
That fire suppression system would have likeley been an old version of HALON, and now INERGEN. You probably aren't going to be spraying water all over that power.

That is a Co2 fire system, but you explained how it works perfectly
Also we got in the tunnel that goes under the motorway with the main fuel pipe that went out to the jetti in gosport!
Thank you for taking us along with you for the great explore. Love the laughs and commentary.
Just got a 4k tv today and the footage on this vid is amazing,what a difference, keep up the good work Mat

Please tell me how to get there
hi unfortunately i dont know where the entrances are and i haven't been in there sorry.
Brilliant explore ✌️
Kudos to just climbing all those stairs. Nice explore!
As an adult, I would love to get into Urban Exploration, we done it regularly as kids, but it wasn't called that then, it was just part of an ordinary 1970s 1980s British childhood 😉👍
But it's top secret and only he and his merry men are allowed down there 🤣
Bet it was hell going back up all them steps x
Iks has been there sliding on that slope shaft
Ian ,Chris been there !!! Thanks Matt!!!; )

It was a real eye opener going here with Matt! Otherwise it would just be a load of old machinery lol. Very knowledgeable
VacantHaven you’re a lucky man !

Very unpleasant and hazardous... less obvious is the high cancer risk from the fuel oil.
Sorry i missed it Matthew love the bunker explores 😊💯❤👍
Brilliant video pal - nice voice for these too! Love Portsdown. I’m there almost every week 👏👌
Born and raised in portmouth and never been able to find people who know how to get into them as always wanted to explore all the history or the town I was born
Those scales were definitely to measure the oil levels in the tanks
Sorry I missed the premier Matthew. I was out all day for my son's birthday. Will watch today ❤
Super explore Matt I bet it was bloody noises when it was pumping .Amazing place x

didnt iks visit here ages ago?
Yes he did, as this site has been reopened you might eventually see another video ;).
yes
its a shame its been trashed so much since they were there 😪
Uncle matt is a wealth of knowledge.
Should be a museum folks as I said to the i k s team when they went there
I imagin the sprinklers would be powder extinguishers because of the electrical and oil content
you should use a stick for the floor to test incase of holes brilliant video
and throw bolts to check for anomalies
@@gordslater yes, and press F6 as much as possible. Don't wanna start at the top of them bloody stairs every 5 minutes.
Don't think Matt has any extra hands for that here but he did take a stick to the mine explore 😉
54:10, that looks like the axel for the rails on the ramp on the way down.
Very cool Matt!
Love this place! It's very sketchy climbing the ladder and looking over the engine room but so worth the experience, glad you did it too! 🙂
May i ask where it is?
There would have been Co2 tanks where you found that sprinkler valve. It was a Co2 fire system
thank you matt nice find in joy watch ...........jy
Keep all videos up amazing
Great video Matt.
Amazing place! Been watching the IKS video from this location too. All that oil is disturbing though.
Priceless knowledge
its not a lifter next to the chopped ladder its a massive contents gauge at 23 mins to go.
Excellent explore Matt Keep up the great work, Thanks.
Amazing history ,and as always to the point.👍
1st class video to watch thank you take care kind regards from me kenneth💜💜💜👍

It was supposed to be turned into a museum but there was peregrine Falcons nesting there so they couldn’t continue with the work
Looked like it said Stokers Mess. Probably the lunch room for staff that worked down there.
Your sprinkler system for the transformer’s would be connected to cylinders of halon gas rather than water.
You can see the cylinder holders underneath the conduit in the corner.
Matt the scale on the tanks is in thousand gallons.
Wow this place looks amazing what a great video.
One funny thing is, first the oil is coming from the ground and going to the factory to make it good and clean, then the oil is going back in to the ground! :)
Hey great video, what song was used to show micheldever station at 11:26 ?
Its a conrod that the piston attaches to on small end & crank on big end bro...
awesome video
“Groves Mess” is in relation to Paulsgrove.
ah. sure looked like am x. guess their tagging skills are wonky.
Liked the explore from Margaret P
"Piston arm" - Connecting rod!
RIP Emu Man
edit: oops that was Rod Hull, sorry
Great!! there goes history well done 👏
I heard a noise at 14:10 right after he says the word "slippery"
I heard that too, its actually after he says "yeah it gets slippy" at 4:11it sounds like a bird squawk or something 🤔🤷♂️
Thanks for the link ;)
A mucky explore Matt, but interesting xx
What was the air like down there . Great video .
STUNK OF OIL
that is a very deep tunnel
Wow that is deep.
Anybody know what caused this leak ?
I love the underground. 🙃 I'm Batman.
The fire extinguisher system would have been connected to co2 bottles water and electricity doesn’t mix you can see the bottle shaped brackets that would have held the tanks the room would have been flooded in co2 should a fire have occurred same system we had in the engine rooms of the ships I’ve worked on
cool 👍👍👍
How do you get that nice 3d view of a town at the beginning
he used 3d view on google maps
The entrances aren't "secret".
Those long tunnels need to be explored with a scooter.
Is that not the one @IKS slid down repeatedly 😅😅🤣 amazing place its like lay out for a sci fi computer game
looks like an axle may have put spear parts near it at disposition
Wheres the entrance ;)
Been there before the stairs killed me walking up and down
what is the name of the construction company?
You appear to be standing in a Superfund Clean up site, as we would call it in the USA. No smoking, eh?
such a massive place - shame its in such a state
Like the Wetherspoons toilets them stairs and there’s still people on their way up that haven’t even heard of Coronavirus yet!!!!
slick video 👍
Este bideo me encanto de berda
it could be a proper underground rave club, just what pompey is missing lol
Grovers come from Paulsgrove the locals who have been in there spidging!
