Wormholes

Using Other Ships to Collapse

If you can't fly an Orca, a Battleship will do the job just as well, albeit a little slower. Just note the mass of your ship, and start subtracting it from the total mass of the hole each jump you make. When the hole goes critical, move on to the HIC method detailed below. Be sure to inspect the wormhole after each jump to see if it has reached its 50% point or even its 10% point. See the top of this post for more information about that.


Using a Heavy Interdictor Cruiser to Collapse Wormholes

To safely collapse a wormhole you want to jump through the hole with a very small mass and return with a very large mass. By entering a wormhole with the smallest mass possible you are taking much less risk of the wormhole collapsing behind you, which would trap you on the wrong side.

Reducing Your Mass:
Warp Disruption Field Generators (WDFG) have a very unique attribute: they reduce the mass of your ship by 80% when activated. So let’s assume (as an example) you are in a ship with a mass of 100,000,000 kg. When you activate the WDFG and look at your ship info, your mass is now reported as 20,000,000 kg. The WDFG mass reduction effects stack as well. So if you add a 2nd WDFG and activate it your mass is now 4,000,000 kg. Add a 3rd and your mass is now 800,000 kg. And so on.

Heavy Interdictor Cruisers (HIC) are the only ships in Eve that can equip a WDFG.

Increasing Your Mass:
We now know how to reduce our mass to make it safely through a wormhole. But on the return jump we want our mass to be as large as possible in order to damage the hole as much as possible. There are several modules in Eve that have this effect.

The most efficient method is to add an Afterburner (AB) or Microwarp Drive (MWD). A 100MN AB/MWD will add 50,000,000 kg of mass to a ship when activated. A 10MN AB will add 5,000,000 kg and a 1MN AB will add 500,000 kg. Again, the mass addition is only in effect when the module is activated.

Another module that adds mass to a ship is a Reinforced Armor Plate. A 1600mm Reinforced Steel Plate I will add 3,750,000 kg of mass. An 800mm Reinforced Steel Plate I will add 1,875,000 kg. There are smaller plates all the way down to 50mm, but their mass addition is so minimal they typically not used. Unlike the AB, these mass additions are always in effect. That is until the module is placed offline.

The Fit:
With this fit our mass entering the wormhole is 45,320 kg, which is the same mass as your pod! Our mass returning back through the wormhole is 78,328,000 kg. Nearly the size of a battleship!

* Note I will add fits for all racial HICs as soon as I get time. For now we will just focus on the Amarr Devoter.

Procedure:
I would recommend using a large ship such as an Orca or a Battleship to bring the mass of the wormhole down to critical. At this point you will approach the wormhole in the HIC and turn on all of the WDFG (note: AB should be off). Jump through the hole. Wait 15 seconds, turn on your AB, and return back through the hole. Note: your WDFG should be off for the return trip.

You will likely have to repeat this one to five times to collapse a wormhole that is critical, depending on the initial size of the hole, how close it is to collapse and how much variance there is in the size.

Feel safe going into a wormhole with only 45,320kg of mass. The odds are you will never collapse it. Good luck!

Using Capital Ships to Collapse

Since we've moved into a C5 with a static C5 collapsing whs have become much much easier. Our static is an H296 which has a maximum mass of 3 billion kg (+/- 10%), with a max allowable jump mass of 1.3 billion kg.

Procedure:
Assuming it is a fresh hole, send a 100MN Orca in (with 100MN on) and bring it back with the 100MN on. Then send in a Dreadnought (NOT a carrier) and bring it back. Hole collapses. On the rare occasion this doesn't finish the hole, simply use a hictor as detailed above to finish the job.

I would highly recommend having an alt/friend sitting the by the hole with 3x webs so that when you return he can insta-warp you back to your POS.

NEVER ever jump a dread through an H296 that is less than half mass. You will regret it. In this situation just start pounding the hole with 100MN orca jumps. Again, if it goes mass crit, don't jump through. Move on to Hictors.

That's about it for a C5 static. Simple eh?

I hope this is helpful to some people. Let me know if you see any glaring errors or have questions.

Fly safe.

For collapsing a 2bil mass WH, I prefer the following:

2,000,000,000kg +-10%
4 orca's, no AB (1bil mass)
at this point, you can see whether or not the WH has reduced. if it has:
3 orca's, no AB (750mil mass)
1 orca, AB on (300mil mass)
Since a 2bil mass WH with -10% is 1.8bil, this method gives the last orca return 50mil mass to return with, without getting it stuck on the far side. But it still puts a total of 2,050,000,000kg mass through, collapsing it even if your calculations are slightly off. Now, if after the first 4 passes, the WH doesn't reduce, that means that you have extra mass, and you should go through:
1 orca AB off (250mil mass)
3 orca's AB on(900mil mass)
this stuffs a total of 2.15bil mass through, leaving a little bit left, but the HIC trick posted above will easily collapse that. And this method greatly reduces the chances of getting something stuck on the far side.

For 1bil mass WH's (C5 w/ C3 static)
2 orca's through, AB off (500mil mass)
if it reduces, send orca through AB off on the way out, AB on the way back. If it doesn't reduce, send the orca through AB on both ways.

Lastly, for 3bil mass WH's that accept capitals, if you don't have dreadnoughts available, you can do it with a carrier/rorqual. For this, run 4 orca passes to start (1 bil mass). Then toss a carrier through (1.15bil mass or so), and bring it back. A dread just means you can forget about one of the orca round trips. I wouldn't recommend trying to close one with just orcas/BS's though...

That's a fine method, but it requires more people and takes more time. When we're rolling holes we want to get it done fast and efficiently. So we have our scan ship with the 3x webs sitting on the hole, he calls the all clear, Orca jumps in, then gets insta-warped out the second he decloaks back in our space. Dread warps in, same deal. Hole is gone.

Anybody that decides to jump the orca will end up trapped in our system within 10-20 seconds.

Additionally, if we're rolling holes, we are collapsing them faster than anybody can scan them down anyways. After 100s and 100s of collapses, we've yet to have a single issue with this method.

Nice guide but you do risk losing ships so the carrier method above is the best choice IMO, failing that use your group of B/S method, that way they can at least defend themselves.

Also rather than using a HIC for closing any hole that is on the 'brink', the other option is to use the lazy mans method - ie use a dumb alt in a Cruiser with 100mn A/B fitted. For instance you can train a virgin alt to pilot a 100mn A/B Rupture in around 3 days. Jump out with burner off and back in with burner on, the odds are high that you'll end up on the right side, if not you warp to a safe spot and self destruct ship and pod - resulting in the loss of a Rupture and 100mn Afterburner I costing around 7 mill in total, but saving you the time of trying to scan out. Then your alt just brings in a new rupture in the next time you have a route.

hah! Yup, you just can't fix stupid.

If an hostile whcoorp manage to "sneak in a carrier" and you dont see it , you deserv to get traped because this is pure scouting fail........

also if its smell fishy just let 2bs with mwd jump befor carrier because then its reduce after the 2bs there is a carrier on your side....

Also befor smart ass comments ye we already got traped by this because of lazy scouting but also traped quite some people with this :)

We don't need to know how everyone does it. everyone has their own way of collapsing wormholes, and this is a great guide for people that have never done it before, or are just starting doing it. They'll be able to make adjustments afterwards.

We've spotted it fortunatly hence why I know it happens - but theres loads of ways you can miss it. Exhale spawned a link to us once and did it immediatly and their wh was off dscan of our POSes and the rest of our players but by sheer chance I had a cloaky sitting out at the far planet and saw the carrier popup on dscan. Another corp did it early on in the day when they thought we were all offline (again I had a cloaky logged in) and had it sitting there for several hours (eventually they got bored and crashed the WH).

Fortunatly we've never lost a capital this way so far, but I do reccomend testing the mass on capital class WHs before putting a cap through.
