New Category... Engineering!


#1

We have started a new category here on the forum… Engineering!<br><br>So give a few cranks on the sound powered phone, stick a post-it on the noon slip and put a gCaptain poster on the Chief’s door. (Not that you need another reason to harass the guys down below!)

<br><br>There are only two places where you can get water. From Mother Earth and from your Engineers. Be respectful…

Engineering is 95% mental.
The other half is physical.

Anybody that will swim in my crap, deserves my respect.

I am very interested in the operation of large ships and to that end would like to know how many crew stand a watch in the engine room of ship powered by a large low rev diesel and what do they do? I really want to learn this stuff, so if there are any books that you know of, I would appreciate hearing about them. “Looking for a Ship” is the only one I’ve found so far.

Thank You, Texino

The typical watch schedule is 4 hours on and 8 hours off with overtime filling up any spare time they have. Many of the new vessels, however, have “unmanned” engine rooms meaning all the negineers work 12hrs during the day but one lucky guy gets to take a beeper type device to sleep with him. If there is a malfunction the computer system sets off his beeper and he wakes up to check the alarm panel. If there is a major alarm or many small ones then the system sets off a buzzer in all the engineering cabins.

I’m not allowed to drive the boat,

The whistle I don’t blow.

I’m not the one who designates

How far the boat will go.

I’m not allowed to blow off steam,

Or even ring the bell.

But let the damn thing start to sink

And see who catches hell !!

Well put Mr. Seadog!

<font face="Trebuchet MS] </font>
[ol]
[li]All pipe is to be made of a long hole, surrounded by metal or plastic centered around the hole.[/li]
[li]All pipe is to be hollow throughout the entire length - do not use holes of a different length than the pipe.[/li]
[li]The ID (inside diameter) of all pipe must not exceed the OD (outside diameter) - otherwise the hole will be on the outside.[/li]
[li]All pipe is to be supplied with nothing in the hole. So that water, steam or other stuff can be put inside at a later date.[/li]
[li]All pipe should be supplied without rust: this can be more readily applied at the job site. NOTE: Some vendors are now able to supply pre-rusted pipe. If available in your area, this product is a recommended thing, as it will save a great deal of time on the job site.[/li]
[li]All pipe over 500 ft (150 m) in length should have the words “LONG PIPE” clearly painted on each side and end, so the contractor will know it is a long pipe.[/li]
[li]Pipe over 2 miles (3.2 Km) in length must also have the words “LONG PIPE” painted in the middle, so the contractor will not have to walk the entire length of the pipe to determine whether or not it is a long pipe or a short pipe.[/li]
[li]All pipe over 6 ft (1.83 m) in diameter must have the words “LARGE PIPE” painted on it, so the contractor will not mistake it for a small pipe.[/li]
[li]Flanges must be used on all pipe. Flanges must have holes for bolts, quite separate from the big hole in the middle.[/li]
[li]When ordering 90° or 30° elbows, be sure to specify right hand or left hand, otherwise you will end up going the wrong way.[/li]
[li]Be sure to specify to your vendor whether you want level, uphill, or downhill pipe. If you use downhill pipe for going uphill, the water will flow the wrong way.[/li]
[li]All couplings should have either right-hand or left-hand threads, but do not mix the threads, otherwise as the coupling is being screwed on one pipe, it is being unscrewed from the other.[/li]
[li]All pipes shorter than ¼ in (3 mm) are very uneconomical in use, requiring many joints. They are generally known as washers.[/li]
[li]Joints in pipes for piping water must be water-tight. Those in pipes for compressed air, however, need only be air tight.[/li]
[li]Lengths of pipe may be welded or soldered together. This method is not recommended for concrete or earthenware pipes.[/li]
[li]Other commodities are often confused with pipes. These include: conduit, tube, tunnel and drain. Use only genuine pipes[/li]
