Any structural engineers here?

right, i see, weve not done other beams apart from the I-beam so far - ready for next weeks lecture

lol what year are you? Even general UC's or UB's would still deflect under the load, but were just trying to give an example of what we would use as the OP has been specified something I would say was well over what is required.

haha - the course isnt specifically geared towards structures, we only have two modules on Steel Structures this year - the course is heavily weighted to Geotechnics

OP, what cross section shape are the 2 existing steel beams? As already said, connections could be difficult, both to the existing beams and to the speakers, especially a 40mm wide box.

Something like a UB 127 x 76 x 13 S275 would be heavier but easier to fix to. You could even connect it to the existing beams without bolts or welding but by using clamps - minimal interference (can't remember the name of the type we've used before though). The heavier mass would help with the vibrations as well.

I hear SS7 are recruiting loads at the moment (and others from the emails I keep getting)

KaHn

Interesting, although I don't think they tend to recruit chem engineers do they?

On a side note looks like I'll be in Aberdeen from ~31st

Everyone seems to be moving to Aberdeen!

Hopefully there'll be some jobs left when I graduate at this rate.

Oh yeah sorry, i keep getting you mixed up with Slambo I think who works for SS7, however SS7 will have some chems there.

Going to try and sort out an aberdeen night out as me and -ad- go out quite a bit, probably mid novemember at the moment.

Can't remember what shape the existing beams are. Pretty sure they have a flat top to them, so are either box, or I shape. Anyhow, fixing the new stuff to them isn't a problem, we have a welder (both the equipment and the person) so will probably weld, although clamps would also be an option.

Chippie,

Your problem will be how you connect the speakers to the new beams, the rest will be pretty simple. Can you provide details of the speakers mounts? Are they bolted, welded, clamped or hung using cables?

P.S - Can I just thank everyone who has posted in this thread. Didn't really expect much response, let alone detailed calculations and stuff!!

Been really helpful.

I've got a couple of mates in Aberdeen atm, sure we can sort something out.

Two chains will be attached to the speakers frame, and slung over the new beam (whatever it is). I believe the plan was to weld some additional material on top of the beam to stop forward and backward movement of the chains. I think it was intended to attach without drilling through the beams.

Don't forget expenses, dinner + pint or 2

Mechanical.

Unsure if I want to stay in Aberdeen or head elsewhere though, decision time is looming in the next couple of months though!

Probably the best way, I would suggest adding stops on the bable to stop the speakers sliding to one side of the cable, normally done with knots in rope but cable is different.

The stops on the top is good but I would proably add some foam/neoprene to stop vibrations as stated before.

Experience at this stage is key, go for the operators then contractors, but it depends on what you like doing, I love working doing calcs and design so I doubt i'll move from my current role for contractors/consultancies.

How hard is it to get into petrochem kahn? I'm an aerospace designer ATM with 10 years design experience and an aeronautical engineering degree. But I have looked into that line of work but seems hard to get in the door, I should be able to do it I just need to convince them of it!

I did aerospace at uni, been a subsea/topside structural/consultant for 5 years, I would say now is the time to jump, you need to try everyone tho, and find someone who would take you in and give you relevant training.

Also when you say designer, thats something totally different up here, a designer is a cad operator who has experience with design (HND/HNC) so I would keep that in mind when you're explaining what you do to people as you are an engineer.

Edit, for your first question (how hard) I got recruited half way through my MSc to join Saipem.
