Industrial strength boat bumper

admin

I stumbled across these pictures from my old job and thought some of you guys might find them interesting. This is from a repair/rebuild project, we cut the whole bow section off of that ferry boat, down to just above the water line and replaced most of the structure and all of the hull and deck plating. This is me fitting up the bumper section. All framework you see is 1/2 x 12 flat bar and the rub rail that I am tacking is a piece of 3" schd. 120 that I cut in half length ways and cold bent into place with dogs and wedges. Everything welded up with 7018 or dual shield. That staging is hung on brackets we made attached to the boat's framework and yes, it is just a few inches above the water. Most of the time we were on this job that water was hard(ice). We actually put about 25k of concrete counterweights on the far end of the boat to raise the end we were working on out of the water a bit.

Reply:That had to be the pits when a boat goes by, and makes waves, and everything starts moving while you're welding.  Dock one way, ferry the otherI have a hard enough time holding steady on solid ground.  I'd be making a mess of that in short order"Any day above ground is a good day"http://www.farmersamm.com/
Reply:Samm,All true, but they made the staging and hung it off the boat itself.  No relative motion between the boat and the staging (and thus the welder    ) that way.  Still do have the entire shebang rocking and bobbing around though.Bent the Sch 120 3" pipe with dogs and wedges. eh?  And a rather BFH too I'm sure.    The best laid schemes ...

Reply:that's some primo work jcwelder. i especially like how you rigged up the scaffold you're laying on and put weights on the front for better welding access. got any more pics?i.u.o.e. # 15queens, ny and sunny fla
Reply:That is one of the lake Champlain ferries . I read a story about that job a few years back . That was a pretty extensive modification  to that old boat,and any one from new england/NYS area knows that area is no slouch on WINTER

Reply:As someone who works in the tug boat industry (we actively bump boats into things daily) ain't nothin' works better than tires for bumping into things and that includes $50,000 Schulyer or Shibata fenders.
