Try to use air lifting bag which is helps you to reduced the weight of the pipeline. If possible please make a basic design and attach here for more information. By the way i am not a Diver i am a LST. But have little bit of knowledge about lifting. Thanks.

The shit thing was only a term...lol. The water blaster could be an idea, and as for the winch cable a ROV could do the trick.<br />
And the report you have is very interesting....

Yes the pig was open for debris to fall through to invert of pipe.<br />
I would have to look back through my job archives to locate a picture and they are 450 miles from where I am at.<br />
first one I built I fabricated a scale model 1/20 size and tested technique.<br />
modeled on existing underground type pipe pigs.<br />
scrapers could be locked in place or worked on load springs for final finish sweep.<br />
You can run haul cable through pipe with a SCUBA diver thruster with line tied to it and pick it up outside…

Suggestion is to come up with a lump sum price to do the job and fab equipment and rentals in mobilization cost present it as a cost plus fixed fee.<br />
lump sum $ amount less mob & demob cost, day rate for personnel and equipment will then be deducted from lump amount based on X number of days to complete work. If work is completed in less then estimated days then the difference is split 50 / 50 with the client which is a win win for both sides.<br />
example lump sum is 125K based on 10 days work,25K fee for mob&demob.<br />
you do job in 5 days cost is 50K leaving 50K you split with client thats a 25K bonus for not being on the job.You just made 100K total.<br />
Inform client you have propritary process. Remember the down time for the client is big bucks in lost production adjust price accordingly.<br />
I parlayed an $1800. inspection into a $6 million project with a 20% profit.<br />
It not the game its how you play it.<br />

When You say shit do you mean actual feces ?. I think once you get a pic of the pig you could probably add 2 water blaster jets that will fire forward at a angle and cause the pig ( neutral buoyancy) to rotate . How are you gonna get the winch cable down the pipe 1000ft to hook to a sled or pig to. Dont give up on the job worse case scenario get fred a pic and specs and throw him a consult $. If you cant do it fast no one else can. I would try to sell it with a added benefit like the disposal…

If you cant do it fast no one else can. I would try to sell it with a added benefit like the disposal that was said earlier. Maybe some filtration that will reduce the cleaning load or a maintenance contract once you build the tool your the only one with it so you got it locked up for a while. Is this water land locked in the plant or does it connect with a body of water? things like alkalinity ,salinity, oxygen level. temp can help in future control if you know the pests habitat tolerances. this may not apply but glance at it <a href="http://marronebioinnovations.com/pdf/zequanox_bg2.pdf" target="_blank">http://marronebioinnovations.com/pdf/zequanox_bg2.pdf</a> Yup, you can use a venturi dr…tag:community.cdiver.net,2010-06-17:2371245:Comment:765972010-06-17T21:07:06.644ZD Laydahttp://community.cdiver.net/profile/DrewALayda
Yup, you can use a venturi dredge to push sand and other irregular, heavy debris to a collection/dump site probably 150' away. given the flow of your pump and the ratio of inlet line size vs discharge line size. I prefer 1/2 ratio with a smaller pump, a 4" discharge with a 2" or 2.5" inlet. Blast and suck.<br />
<br />
I have used three configurations.<br />
<br />
Diver in hole with blaster and venturi intake, each separately , diver blasts clean 6' square, then vacuums up with gold dredge. I found this is actually…

<br />
Diver in hole with blaster and venturi intake, each separately , diver blasts clean 6' square, then vacuums up with gold dredge. I found this is actually fastest. When diver is blasting he holds the dredge on bottom below the area being cleared with his foot, a good amount of the debris settles down and is sucked in, requiring minimal time spent "sweeping up"<br />
<br />
We tried other methods that had a hp jet discharge proximal to the inlet, didn't work as well, except for clearing silt from a settling basin for example, sand and shell pissed it and the diver off in that mode.<br />
<br />
Also used the configuration as an experimantal pile jetting/suction setting technique, kind of like a leave in place jet-string, with the jet component and suction/venturi dredge removed from inside the leave in place pile/airlift, the pile then gets the grout. Worked good.<br />

Okay I see, how far would you go with the depth of the wiper. Did the middle of the pig was open, like could you see trough, so water can flow and sweep the mussel as we go<br />
.<br />
Would you have a picture of it by any chance.<br />
<br />
Thanks

made out of steel, wiper blades used extension bars to extend wipers against pipe sidewall.<br />
wiper bars could be set for depth of cut.<br />
measure depth of mussels on side wall and estimate volume of material for removal; example three inch's of growth = 235 cu. yards debres.
