that video makes it look so simple! i reckon it must be a nightmare making the cut completely separated - trying to pull the two halves apart only to find bits still welded together!

I've worked onboard several DSV's & oil construction vessels that have been cut & stretched & some widened too.seems a fairly comon thing with oil industry vessels
Although they dont go for the seamless join as in the video you can usually see the weld scars
Cool video though wonder how long it actually took to do the entire job
