I work at a large refinery on the gulf cost and we use-settling tanks to pull hydrocarbons off our runoff water, heating the water will also increase separation.

one thing more the stripping pump is NEVER PUMPED OVER THE SIDE! always to a stripping tank which is allowed to settle then the H 2 o is pumped over board and oil if any pumped to a tank other than service tank!

And any oil king worth a dam will have samlpes of oil he pumped in to F O Servive tanks taken at different intervals just in case !!! they were kept in the oilking water king shack also when recieving fuel oil from shore or fleet oilers sample are taken and retained ! and a lab report will be forward to engineering office ie flash point, flame point sed rate temp rec'd etc!

yea but!!! The sevice F O tanks were neva ballasted!!!! only the storage tanks were as they were mt'd Service F O tks were always in use for the firerooms after filling a service tank is was sounded for H 2O content before it was put on the line only tine one picked up water was with the stripping pump its p u is right on the bottom it is a small reciprocating pump lots suction not much volume KABISH! to sound for moisture the sounding bob was coated with a moisture reactive paste it turn...

It is counterintuitive, is it not?

Keeping full tanks for DDs was as must for stability reasons, as I've disucssed, and putting sea water (ballast) into empty tanks was the only way to do it. Pre-'compensating' fuel tanks, the tank had to be empty to try to avoid the problem you've mentioned. Like most fuel tanks I expect, one could not pump down to actual empty. Water was always going to be in the fuel to some extent, so the tanks were periodically stripped via a...

I served on the Bradley (DE-1041) which had the compensating fuel tanks. I don't remember any problems with the fuel system during the first several years of commission. The DE/FF-1052) class also had the same type of installation, and while on the Cook (FF-1083) during the first years of commission we had no problems with contaminated fuel.

The immediate consequence of the storm was as noted, an increase in minimum acceptable fuel level. Post-war the DE-1040 class inaugurated the concept of compensating fuel tanks whereby oil suction was taken from the TOP of the tank, constantly replaced by firemain ballast water coming in at the bottom. Taking on fuel merely reversed the process, with the ballast being...

at battle speed bound for the Philippine Islands. We were burning about 400 gallons of fuel oil per hour. We pulled into the Admiralty Islands to refuel.

They charged us $1.00 per gallon for the fuel oil.

The Commodore said Hell we gave them the fuel oil in the lend lease program.

The Commodore told the engineering officer to figure out how many gallons it would take to get us into Subic Bay and that he wanted the ship to be running on fumes when we got there.

The WW II typhoon story is somewhat more complex with respect to stability.

Two of the Farragut class DDs were right on the ragged edge of acceptable stability. Recall Halsey was trying to refuel. Standard practice for DDs was to ballast fuel tanks with water as they were emptied, so although fuel capacity was going down, the virtual center of gravity was not rising thereby.

However, to refuel meant (in those ships) pumping out the ballast water to make room for the fuel...

Now who would have ever thought that.

Well, how about the Japanese? Prior to WW II, they had several ships capsize in heavy weather and others were damaged because they had tried to cram too much armament into hulls that were too narrow and/or lightweight. They were trying to build ships with maximum firepower, maximum speed, and maximum protection on hulls that were too light; something had to give.

several ships capsize because they had run run out of fuel oil when a typhoon struck a directive was issued that no ship should go below 60 percent fuel oil.

When a ship losses power and cannot control how the ship is positioned to the wind and waves she is helpless.

Strange as it seems not all ships will capsize when they lose power.

Our ships were top heavy which means that once they roll to 45 degrees they should capsize because at that point the top is...
