Launching A New 120 ft long Push Boat

[jackieschmidt]

I thought some of you might find this interesting.

I was out at San Jac Marine today starting an align boring job on a bearing conversion, and they happened to be launching their latest boat, a 120 ft 3600 HP push boat. They build them on dry land, then literally shove them onto a waiting dry dock sitting long ways to the bank.

they use three Truck Dollie’s under the push knees, (24 wheels total), with three large air bladders under the hull. They use a 175 ton crawler crane to roll the hull onto the dry dock. As the vessel starts on the dry dock, they have to constantly keep excavating water so the dock will stay level with the bank as the weight progresses onto the dock.

After the entire thing is sitting on the dry dock, the sink the dock, float the boat off and then raise the dock to removal of the bladders and the Dollies. They then place the boat back on the dry dock on it’s proper blocks to be finished out.

here are some pictures. The last one is one of our shafts in the Stern Tube Bearing.
I had a thread several months ago on align boring the shaft lines.

We are starting on all of the machine shop work on their next two hulls, 120 ft and a 86 ft featuring diesel electric power.

A lot of boats that never get within 2000 miles of Delaware are registered there. It has to do with some corporate tax provision that Delaware offers.

A lot of companies are registered there for the same reasons.

Very cool Jackie.

About 2/3rds of the publicly traded companies are incorporated in Delaware.

They will do that when the boat is christened and ready to go to work.
launching one like this is not near as dramatic as a vessel sliding down he shipway and being in the water in minutes.

This “launch” is about a 10 hour process.
