Re: STERN TUBE HIGH TEMPERATURE DURING MANEUVERING

If the prop was only partly immersed it would vibrate like hell, all that sideways thrust on the bearings would heat things up Nicely!!
If they caught it in time they may have been lucky and no further damage done, if not, it could be a big dry Dock job.

Re: STERN TUBE HIGH TEMPERATURE DURING MANEUVERING

If the oil temperatures goes up, either the cooling system isn't working properly or the the prop shaft is generating more heat. So first check the cooling system, simple things first, are all the valves fully open, clean any filters, check the current drawn by the pump motor, it will INCREASE as th...

Re: Sewage Discharge Requirements for a Canadian Flagged vessel entering US Waters

If you look in Marpol you will see the regulations regarding sewage and Grey/Gray water discharges for all vessels sailing outside their own Coastal Waters.. Basically raw sewage can be discharged into the Sea but you have to calculate the volume discharged per hour and the ship's speed per hour and...

Re: SMS, the Holy Grail?

I agree they don't have a Religion or believe in God, that is my point, when people did they expected to be called to Judgement and have to justify all their actions in life to St Peter before being sentenced to Hell, or Purgatory to do penance for their failures. Unless they were perfect and went s...

Re: SMS, the Holy Grail?

Well Jk sometimes just a few seconds stretch out...Remember to measure twice and cut once! I think that one thing that you and Martin have missed out on is the lack of PERSONAL Responsibility. Nobody looks at a situation to think if that is safe, they look at Class Rules, Flag State Rules, IMO Rules...

Re: SMS, the Holy Grail?

Maybe the article, below, from the Times, dated Thursday 25th January 2018, helps to explain what happens. It postulates that if Psychopaths rise to a position of power in any organisation, they then drive out everyone who isn't a psychopath. It is a bit like Gresham's Law in Economics, (Gresham was...

Re: Celebrity Edge Rollout

Maybe the Moving Restaurant could be fitted with Engines like Merlyn said and be used as an Emergency Evacuation System instead of Lifeboats, it would be much easier to coax the pax into it than conventional lifeboats.

Marine Refrigeration

Marine refrigeration. During my time at sea, I have found that Refrigeration is one of the least well understood systems on board ship. Generally Refrigeration Plants are ignored until they break down and then everyone panics. So I thought that I would try pass on some of the hard learnt knowledge I...

Re: main bearing measuring tool calibration

The measuring tool appears to be a standard depth gauge, so the usual way to test it would be to put it inside a standard test piece, supplied with the gauge, it might just be a length of pipe closed at one end, and I would expect it to read "zero" when fully inserted. I don't have any personal expe...

Re: Advance timing for fuel pump

Delayed fuel injection should not cause Carbon Build up on the air inlet valves. The only way that I can see this happening is if the air inlet valves are still open while fuel is being injected and burnt!! So either the injection timing or the valve timing may be a long way out. I would suggest put...

Re: Advance timing for fuel pump

Hi Rhaipol, welcome to the site. Advancing the fuel pump timing will increase the P.max, but can reduce the power output of the cylinder and damage the engine if the timing is advanced too much. This is because ignition and combustion will happen during the compression stroke, instead of combustion ...

Re: TheNavalArch - Ship Energy Efficiency Design Index (EEDI) Calculator

In my experience I would say that calculated measurements are almost always higher than measured ones, the calculation is on the basis that every component in the system is "perfect", and that only happens on the "Test Bed", not at all representative of the real world. The parameters for most Test B...
