Re: Fuel Additives

I have now read the links and they claim that the product is a"Surfactant and Dispersant" I take this to mean that it is emulsifying any water in the fuel with the Fuel, and dispersing both the emulsion and any solid deposits or sludge evenly throughout the fuel, so that the dirt and water...

Re: Fuel Additives

The Cetane No is basically the reciprocal of the Octane No on another Scale. The Cetane no of the fuel depends on the Chemical constituents of the fuel. Fundamentally it is a measure of the compression Ratio/ compression Temperature you require for a special Diesel Test Engine to run on the fuel wit...

Re: USS Indianapolis wreck discovered

There was a Class of British Destroyers a generation ago, that the Politicians became involved with designing, they took out a 20 foot length of the centre section to save construction costs, after a few years the ships didn't have the internal volume or Displacement to fit all the upgrades required...

Re: USS Indianapolis wreck discovered

Well JK, Call me an old cynic if you like, but the USN sacked several Officers and took disciplinary action against others after their other Destroyer collided in the Sea of Japan. I suspect there is high probability that the OOW was updating his Facebook profile, or something similar, at the time o...

Not to mention the Fat Government Pension when you go, you don't get company pensions any more if you go to Sea.

Re: Doom and Gloom

Hi Sea Rover, I don't know what your standards are in Canada!! I have sailed with a few Canadian Deck Officers over the years but no Engineers, I would never draw conclusions about Natuional Standards on the basis of a handful of individuals. Many of the Europeans go to Uni and get a Degree In Nauti...

Re: Doom and Gloom

Sea Rover, I didn't comment here because I was born and live in England and did all my studying and certification on this side of the pond, therefore I do not feel qualified to discuss changes in Canadian Rules that I do not know anything about and do not effect me, especially since I was made redun...

Re: Common Rail Engine 48/60 cr

Interesting that I interpreted the original report of "Not to mention while not part of the CR fuel system every cylinder on both engines had cracked land rings" as being the Entablature Lands that the liner sits on, Merlyn interprets that as "We also had several engines with piston d...

Re: Common Rail Engine 48/60 cr

Glad to help, it sounds strange to have finer filtration before the fuel module than after! After all the filters before the fuel module are to protect the fuel booster pumps which are pretty tough when compared to the fuel injection pumps that are protected by the engine filters. Very hard to get C...

Re: Common Rail Engine 48/60 cr

Atlantic has a point there, another think to look for that I have seen, is that some "Engineer" has found it difficult to compress the springs when installing cartridge filters and has thrown the springs away, because they did not consider them to be neccessary! Of course if you do that th...

Re: Suicide and sea

How do we deal with them, JK? Traditionally the Captain was "Master under God", and responsible for everything and everybody on board, the Officers and Crew signed "Articles of Agreement" which were basically a contract between the Captain and the rest of the crew. Only the Capta...

Re: Common Rail Engine 48/60 cr

Sorry no experience with this engine. I guess a lot of the problems might be due to fuel or lack of cleanliness in the assembly and flushing through of the fuel system when it was commissioned, so it might get better with time. However, the days when MAN engines were built in Augsberg, Germany are l...

Re: Mouldy Navy

I believe Warships use activated Carbon Filters to remove Nuclear, Biological. and Chemical Agents from the Fresh Air drawn into their "Citadels" which are the protected areas inside warships. Even the engines and boilers have combustion air ducted in from the Deck, so at that only a small...

Re: Mouldy Navy

Interesting what Dave is saying, but most A/C units I have seen had baffles after the cooling battery to try and strip droplets of water out of the air flow. Regarding balancing the the recirculation, I have usually set this up with the Fresh Air Damper 100% open, and the recirculation damper open 1...
