Abrasive blasting? 

 

[Hudds Lad]

or Ablative blasting?

[Arthur Marshall]

Evasive boating, surely.

[Alan de Enfield]

Invasive 'sand' blasting ?

 

Evasive means 'to avoid' so maybe they are avoiding blasting ?

Or

Should it read in full "boater should take evasive action to avoid blasting" ?

I thought it was a quick blast on your horn at a blind bridge to evade a collision.

In view of several inter-related posts about the abilities of CRT, there should be no surprise as to wrong words being used. Perhaps there should be a pervasive study made into CRT practice and performance by an old fashioned quango. There was a time when waterways staff knew the networks they were concerned with. The increasing number of posts on this forum lends to a concern that they do not. Fragmented repair work does not help the lot of the boating population and cosmetic alterations such as what was planned at Market Drayton without regard to boaters needs, does nothing to support any understanding of the network. But then those working from an ivory tower in Birmingham, or elsewhere around the UK, may not understand and it the fault of management when such failures are not rectified.

At our yard we used to use extreme high pressure water blasting for cleaning hulls etc. It is at a pressure that would do severe damage to your body parts if you were foolish enough to get them in the way, and meant there was no sand or grit to be cleared up - just the rust and scale debris. I believe this is known as evasive blasting.

This is the same process used by the Belgian shipyard where we dock our barge, and you can get an idea of the pressure from the angle he is standing at     😧  (I hasten to add that that thing is not our barge!)

We use it in the construction industry for demolishing reinforced concrete but leaving the reinforcement, it is known as Hydro Demolition, lots of stories about operatives losing feet through accidents!

...... and at the end of the job all there is to clear up is a mound of mussels  (Osman has managed to keep his feet all the 20 years or so we've used the Vankerkoven yard  🙂)

I presume that there is a high pressure fryer somewhere  producing frites to go with the moules?
