Propeller polishing cruise ship #3

Two divers polishing propellers in Mexico. They are using a very high speed, water-drive device that can polish both propellers in less than 4 hours!

Sorry for all the questions: wouldn't you run the gauntlet of sharks in these waters? If so wouldn't the procedure/decibel of the cleaning machine actually attract them?

[shyetet]

Sharks don't normally attract to large vessels at berth in these waters. We believe that there is alot of free electrical current discharging from the ships in way of cathodic protection and echo sounders that would tend to repel them from venturing too close. It may be also that there are just not alot of sharks in this particular location...

Thanks for your response..

I'm sure you can see the dock bottom, at one point, hence my question on depth.

Is the clarity of water camera-enhanced or naturally as workable, as seen on screen? I doubt in a British dock (of any description), you'd have more than 5-10 feet of visibility, the water's so poisoned and opaque.

[shyetet]

Yes, the water is really that clear. Cozumel, Mexico. approx. visibility 100ft

Perfect location for any underwater work.

[MatlockJack]

Why not just do this in drydock?

What depth of water was she lying in?

[shyetet]

This is interim maintenance service being performed. There is a 3 year interval between drydocking. In-water polishing is far more cost effective and better quality than dry polishing in drydock. Vessel was berthed pierside for the service. Depth of water under the pier was approx. 50feet

That would scare the shit outta me

[2ndOfficerCHL]

Very interesting. What vessel were you working on?

[cj382]

@cr90147 ...topside, repeat. do NOT start the engines!

[theedit123]

@mageac people are scared of these things is because the could chop you up if you get sucked into one

[Altanore]

@cr90147 It has happened...

[mageac]

why in the hell are people scared of propellers...

[MrFelt1000]

hey whats the ships name and what cruise line

[fjbutch]

Uh Uh ...missed a spot .....

[MatlockJack]

@TheSimonHarris

By means of pollution, which can occasionally be toxic. I'm not suggesting the water is augmented with Warfarin or weedkiller...

[TheSimonHarris]

@MatlockJack poisoned?

[deville9549]

@cr90147 me too
