Sub atlantic high pressure water jetter experience…

[Savante]

Does anyone have any experience using the Sub Atlantic High Pressure Water jetter for removal of marine growth, shallow water work – likely barnacles ?

We are looking to rent one on a short-term basis but looking for anecdotal evidence and tips. Firstly looking to see if anyone has any experience in optimising the standoff distance between the nozzle tip and the target.

From the spec sheet, flow rates at 13lmp and circa 2kpsi….

Kind Regards,

Hi, If you are wanting to clean marine growth like barnacles (harder stuff) 2000 psi won’t make the grade. It will clean soft growth but hard stuff like barnacles, oysters and coral look towards 5000psi. I was on a job last year and had to clean welds for inspection and we used a deck mounted system at between 8000 and 10000psi. The nozzle tip has to still be very close to the site at this pressure like between 100mm and closer.

So if you are going to go the Sub Atlantic systems the high the pressure the better 520bar unit is nice and I have used it before.

I have also done a few jobs in the past like clean platforms and the underside of FPSO with a hard rotating brush system which works great at removing bulk amounts of marine growth.

I think it will definately end up being a combined tooling approach we use. Thanks for the info Haree – very detailed !
