SHIP TRIVIA
Do you know what the short forms “ss” “tss” and “ms” stand for?
. . . ss = Steamship
. . . tss = Turbine Steam Ship
. . . ms = Motor Ship
The “flag” state is where the ship is registered.
The “port” state is where the ship operates.
The ms Rotterdam consumes 120 tons of fuel per day (31,000 gallons) and goes 15 feet per gallon …. It has 5 diesel generators, but uses only three, leaving the other two free for maintenance activities. It weighs 90 thousand tons and can go up to 55 knots.
How does a ship handle its waste?
60,000 gal. sewage
66-110 thousand lb/wk
5-9 lb. solid waste/day/person
Food waste is ground up, the water is removed and it can then be mixed with paper waste. This can then be incinerated and the ashes scattered at sea. Paper and cardboard can be either baled and sold on shore, or also burned. Other solid waste such as glass, plastic or aluminum is sorted. Glass is separated by color for recycling on shore, either whole or crushed; cans are crushed and plastic is shredded. In some areas this waste can be sold and the funds are put into a special recreation fund for the crew.
WATER:
The ship has its own purification and deselination systems which produce 700 tons=185,000 gallons of water a day -- they use 158,000 gal/day. Economizers put sea water under vacuum pressure, it’s turned into steam and then cooled again and the water is collected. “Gray water” from showers, cooking, bilges etc. is purified by running it into tanks where it is treated with enzymes and chemicals that break down the solids, then purified with UV light which produces carbon dioxide and water. Many countries do not produce drinking water that is this pure!
Holland America Line is very conscious of the environment and has strict standards of their own, in addition to international regulations that must be adhered to.
