A couple months back, we had Maxi-DUB swivel no. 250102 come in for overhaul. That swivel was 11 years old and we called it The Old Dog.
 

The Crossing Company of Nisku, Alberta did one better – we have another 250-ton HDD swivel in for service: no. 250101. Built in October of 1997, it’s a full year older than The Old Dog, and I don’t know what we’ll call this one now. “Rusty”, maybe!
Internally, the swivel’s in good shape. The Crossing Company have taken good care of this tool. A new bearing set, seals and a recut of the API thread, and it’ll be good as new and back in service for a fraction of the replacement cost.
In the 90’s, DCD Design pioneered the Maxi-DUB swivel design with two sizes, the 150-ton & 250-ton. Since then, others have duplicated our patented design while we have steadily added to the line, and now we range from 110-ton through 700-ton swivels (100 – 630 metric tonnes) to fit any big directional drilling rig.

PS. Can you read that nameplate? No, neither can I! But the serial number can be picked out, just barely. Besides that, we had trace marks on the swivel and documentation on file so we could confirm the serial number while servicing the swivel.
