A very sad truth.
I think it is solid evidence that despite the introduction of STCW etc the standard of Seafarer training is declining rather than improving.

Re: Dirty/brown/orange colour cooling water
I agree that it has to be something to do with the overhaul and it very much sounds as if exhaust gas is blowing into the cooling water. You say that the water level goes up when you start the engine, does it go down again when you stop it? This is what you would expect if Gas was leaking in. If the...

Re: Dirty/brown/orange colour cooling water
The temperatures are far too cold, you could have cracked the castings running them that cold and you may be getting gas blow from the cylinders into the water. I had cracked heads on one ship with MaK Medium speeds, we didn't lose any water, but when the power came up (and the cylinder pressures) e...

Re: Engine cannot start
When I was a Junior Engineer, back in the 70's, I joined a ship called the Strathleven, (ex Middlesex, ex Jellunga) that had been built in 1953 with twin RSG Sulzers. Before I joined, the Third on watch had heard a knocking noise from one cylinder and gone to get a screwdriver to use as a stethoscop...

Re: Premature pipe failure
I recently had an email from an old Cadet of mine and he told me that he was on a Diesel Electric PSV, and they had found that the Electromagnetic field from their 3 phase 690 Volt power cables was inducing a circulating voltage in the pipework! Which I had never heard of before, might be relevant.

Re: Dirty/brown/orange colour cooling water
Possibly while the system was drained down for the overhaul work, the insides of all the cooling system corroded and this is now coming into the cooling water. Unitor /Wilhelmsen etc make a commissioning cleaner for de-greasing and de rusting new pipework systems, maybe a power flush with that follo...

Re: Engine cannot start
Many years ago, I had a problem with a Paxman 4RPH, got a high exhaust temp alarm, seriously high and stopped it, Chief, Third and myself spent a week working on it trying to find the problem, 16 hours on 8 off. No Instrumentation on the engine, just a single exhaust gas thermometer after the Turbo....

Re: 220V Insulation monitor, Low resistance/Fault from non earth TVs
I have had this experience several times and I have heard possible explanation, firstly you must remember that TV sets are designed for use ashore where the power supply consists of one live wire and a Neutral wire which is connected to Earth at the Star point of the supply Transformer. On a ship we...

Re: Premature pipe failure
I suspect that the impressed Current system is either not working correctly or is set up wrongly. Go back to the Instruction Manual and see if there are set of settings for the "as installed" condition" and see if they are still the same. It looks as if there is too much current flowi...

Re: Black deposits on fresh water side plate coolers
Poor cooling water treatment. The pipe work is rusting to form Black Iron Oxide (due to lack of Oxygen) which is dissolving in the circulating water and being deposited by Galvanic action onto the Heat Exchanger Plates which are less re active than the steel pipes.# Same as the steel Hull corrodes, ...

Re: Stern tube
There should be a Hydrostatic pressure balance between the water outside and the oil inside, because Sea Water is more dense than oil the stern tube header tank is always higher then the Sea Water outside, in proportion to the different SGs. Has the Draught aft increased ? That might cause Sea water...

Re: working in the UK
There used to be a lot of Canadians working in the North Sea employed by British Companies on British Ships, through British Agencies, the North Sea is picking up again so may be worth having a try. They will pay your Air Fares for each trip.

All valves connected to the ships shell or side plating have to be spheroidal Graphitic cast iron or cast steel, if they fracture and break off the ship will sink! Similarly if the pipe between your Fresh Water Generator and the overboard valve rusts through- Hot concentrated Salt Water so very like...

The size of the Gravity Disc is chosen according to the specific Gravity of the oil to be purified at the temperature at which the oil will be purified.
