My father is on an oil tanker, in a piracy region, near Somalia. I need some ideas on how to secure the crew.

No weapons allowed on it, btw.

So far this is the plan:
They got barbed wire around the ship, with bells attached to it. And also, one across the middle of the ship. (shit is more than 200m long, and 50m wide). There are always 2 crew members in guardia, the command bridge, guarding. They have 2 radars, one on 6 miles and other one on 12 (but I don't know what good is that for, pirates use plastic or wooden boats), aaand they got IR vision goggles. Or whatever's that called. Also, there are tiny bells on the barbed wire, so they should be heard if anyone tries to cut it. On alert, they all run to citadel (i don't know the correct term in english). And they are safe there. The door of that part of the ship cannot be opened from the outside with no tool or weapon Somalians have.

So I've come to /sci/, to see if there's any more ideas I could send to my father, for their safety. I suggested making a barbed wire an electric circuit, and adding LED's all around, so it's easily noticed when the wire gets cut off. He said he'll throw that idea on the table, but thinks it's not doable.

Do you have anything?

I guess they only have /diy/ solutions availible limited to a few hundreds USD in cosst.

So, IP cams with face recognition and IR illumination sounds like a pretty decent idea. There's software(vitamin D for example) that can be made to trigger email alerts or alarms based on detection of treshhold overruns or other arbitrary yet user friendly specifications.

Okay, I'll give you that. I think that /sci/-s user base likes thinking about clever solutions, and is also a creative group. I don't think it's that far from the topic, and might be fun for discussion.

If you do not like the thread, you are excused, this is not the only off topic alive atm, and most definitely not the worst one.

Put slippery stuff down around the outside of the ship, and tacks around so when they climb overboard the will slip and fall on the tacks

Give them the spicy keychain, use an iron or torch to heat up all the door handles really really hot

If there are some stairs, booby trap them with heavy objects that drop down

Throw bricks at them as they try to climb up the side or spray over the side with bear spray

Light the ship on fire as they get on board, then go to a place where there is no fire, maybe an inflatable pool?

trick them, find a really really good hiding place, and leave all the doors open going to the control tower, then after they go in lock the doors form the outside and barricade them inside, also apply the spicy keychain in reverse here

ship me to mogadishu and give me two days to scrounge up the materials to open that door.

also they can hold the entire ship hostage simply by threatening to blast the hull. if the ship's sinking the crew is gonna wanna get outta there.

if they're already at the ship the only thing you can do is kill them or pray they don't find anything interesting.

you could get a load of quadrotor type drones and use them to fly around a certain ship perimeter and make a laser, and or bio scanner grid near the water surface. the drones would automatically dock, recharge and trade spots. if an intrusion or approach is detected the alarms go off and the ship lights up, and then you can use microwaves or sasers to grill them. or rig the drones with small pulse bombs that disable their motors. i dunno.

>> No.5473389

>>5473376
How do they scan that big of an area with a face recognition software? And there's really no need for that, anyone outside the vessel is a danger. They do not need to see who it is.

The pirates, they literally climb the "walls" of the ship to get to the deck, and then they go inside the ship, trough one of the 8 doors. That's all there is to it. So the main focus here is to detect them while they're coming, or preventing their climbing. At night. They don't do that during the day.

No need. Once you get behind the door, you are safe.

There can be too many of them, could only make them mad.

They have high pressure water guns. But it's water guns against heavy weaponry. Too risky.
>Light the ship on fire as they get on board, then go to a place where there is no fire, maybe an inflatable pool?
Oil vessel with constant flammable gas emissions. You don't want fire. Anywhere.
>trick them, find a really really good hiding place, and leave all the doors open going to the control tower, then after they go in lock the doors form the outside and barricade them inside, also apply the spicy keychain in reverse here
No remote control of the doors. Too risky to do manually.

>>5473386

If the crew safely escapes to citadel, they give up, most of the time. They clean valuable stuff from cabins, and that's it. The crew stays safe.

So a thermal IR camera should do a pretty good job, the feed could be analyzed for heat blobs on the water and sound an attention signal or alarm when it finds one?. One or two should eb enough, they could rotate on servos to scan the horizon.

They got those. But the navy is always late. Sometimes, they don't even respond. It's Africa...

And it's not about home alone tactics, as I already said, the main focus is on being aware that they're coming. If you see them on time, you save your sorry ass.

This right here, the only solution that you can really do without weapons are
1 Block them access to the ship (most likely impossible)
2 Get a warning that they are coming to your ship
3 Hide in the safe room
4 Wait for the navy

Just invest in an electronic detection systems and the phones, you don't really need anything else.
The system they have in place seems to be good.

Yeah, I hope so. Just wanted to run it by you guys.

>>5473467
If you detect them soon enough that you can run them over (which isn't possible anyway, they have motor boats, much faster than the 300m vessel), you are already safe, by escaping to the safe room.

I found something called "p-trap anti boarding device". You hang lines thin lines from the sides of the ship, that float, 10 meters from boat to ocean. And when motor boat is approaching, you fuck up its propellers, and they are not able to move. It's brilliant, but also, unavalible.

>> No.5473522

>>5473359
I know someone who was involved in this industry and I have heard some stories of the issue (of pirates).

FYI: the "no firearm weapons" rule has partly to do with the companies' desire to avoid liability issues, and partly to do with the problems of entering & leaving multiple international areas with different laws about firearms ownership.

one thing that would be kinda funny is to have the bridge doorknobs wired up so that you could run electricity to them somehow. like 3000 volts. And barricade all the regular doors so they can only try one that is out on a ledge with no railing, so that they will fall overboard after touching the 3000-volt doorknob

course after the first guy, the rest would probably get in anyway and kill you just for that. watching the look on that first guy's face would be awesome tho

>> No.5473536

>No weapons allowed on it, btw.

I know why they do this (liability and port procedures), but I feel it's an immensely stupid restriction and pretty soon we'll have to move past it and start having armed guards full time on ships in that area.

Yeah.. I feel armed guards are the only real solution. Giving weapons to the crew itself is not really responsible, as there are many mental break downs, people do not always deal very well with isolation, and seamen are just regular people, really/

It should be pretty doable. They have electric systems on the ship all right. Barbed wire is of course not the best of conductors and if it's long loops they would need to feed it quite high voltage. to compensate for the drop. It could quite easily be wireable with some simple voltage meter to sound an alarm when the circuit is broken: wire cut.

You don't seriously think think the company is going to tolerate you making all these changes? They don't care enough about your dad to invest in armed guards or an escort vessel. The crew is expendable, minimizing costs is the goal here.

Yes, that is completely true.

They did pay for the barbed wire though, and they do not care about the changes, as long as it does not damage the ship. They area always looking for the ways to increase security, and such "patents" are always free of charge.

Able seamen don't come cheap, you know. Officers even less so. They don't use armed guards on oil tankers because they're essentially giant, floating bombs and carrying weapons can be legally tricky depending on port of call (you might be declared gunrunners or pirates yourselves).

There are all manner of other defensive mechanisms that ships employ beyond simply stringing up barbed wire. The most effective are probably water cannons and water curtains to repel boarders, which are probably ideal for a tanker since they don't involve fire (and the water supply is ample). Some ships also use crowd-control sound cannons to disorient attackers.

>> No.5473666

>>5473658

>giant, floating bombs

Do you actually believe this? Don't you understand what crude oil is?

And virtually all ports will allow you to dock so long as weapons are secured in a lockbox in the propoer fashion and remain there for the duration of your stay. The idea that a legitimate ship would be "declared" a pirate because it's carrying properly secured weapons shows that you have no understanding of anything.
