It's water main pipe. Polyethylene.

It will be PE 100, but I can't quiet pick the size from the photo. Probably 250 outside diameter. The end looks a lot like a towing head for underground directional drilling. That is how most water main is installed. For water main though, the towing head is only installed on one end. If it has a head like that on both ends, then someone has jimmied this pipe up to be some sort of floating boom, or other non pipeline use.

I note the towing eye is stainless. Civil contractors would never bother with that, indicating it is designed for marine use. Which would also explain why it's in the marine environment.

So not sure what it was being used for, but that is 100 % standard watermain pipe.

The 100m long black pipe is the property of salmon farming company Huon Aquaculture, which is based in Tasmania, Australia.

 

After losing the pipe, the company immediately launched a search involving a number of vessels and aircraft but it was not found.

 

Since losing the pipe Huon Aquaculture have moved to orange pipes to make them more visible and they also fit them with GPS tracking devices.

Huon Aquaculture is investigating options for retrieving the pipe.

shows how expensive they are

 

but hit 1 of those, square on, in the middle 50m, with a blunt bowed vendee boat travelling at 17 knots 

 

 

what could happen?

 

maybe they should go back to swept bows?
