Tricky discharge at <strong>the</strong><br />
Mhes Zi terminal<br />
One late afternoon M/T Bow Quizzy<br />
arrives at <strong>the</strong> infamous Mhes Zi terminal<br />
to discharge a part cargo of exactly<br />
870 metric tonnes of some product,<br />
with a specific gravity of exactly 1.<br />
Un<strong>for</strong>tunately <strong>the</strong> terminal’s volume<br />
meters are out of function, and <strong>the</strong><br />
receivers flatly refuse to trust <strong>the</strong> vessel's<br />
measuring equipment (despite<br />
<strong>the</strong>se obviously being fully reliable, this<br />
being an <strong>Odfjell</strong> ship). Without delving<br />
into <strong>the</strong> darker and more sophisticated<br />
corners of <strong>the</strong> charterparty and its<br />
legal aspects, <strong>the</strong> captain, <strong>the</strong> terminal<br />
and <strong>the</strong> receivers agree to complete <strong>the</strong><br />
discharge with <strong>the</strong> help of four empty<br />
shore tanks of 920, 605, 410, and 65<br />
cbm respec- tively, plus an empty open<br />
container of 30 cbm. All volume figures<br />
are exact. The terminal’s old crane can<br />
lift <strong>the</strong> container, while <strong>the</strong> o<strong>the</strong>r tanks<br />
are fully stationary. Due to <strong>the</strong> extra<br />
work of connecting lines between <strong>the</strong><br />
various tanks, each product movement<br />
takes one hour regardless of <strong>the</strong> volume<br />
transferred. Obviously, Bow Quizzy<br />
wants to complete <strong>the</strong> discharge<br />
in as few transfers as possible, to keep<br />
time in port to an absolute minimum.<br />
For sake of simplicity we assume that<br />
product may be moved between <strong>the</strong><br />
various tanks without any loss whatsoever,<br />
we disregard any volume<br />
changes due to temperature variations,<br />
and cargo transfers will not<br />
affect <strong>the</strong> product quality. All tanks are<br />
clean and tank coating is not an issue.<br />
How can <strong>the</strong> crew discharge exactly 870<br />
metric tonnes (and we do not accept<br />
any “more or less owners’ or charterers’<br />
option”) with <strong>the</strong> help of <strong>the</strong> five<br />
empty tanks (but not necessarily all of<br />
<strong>the</strong>m) in as few product transfers as<br />
possible We await your suggested<br />
solutions by June 1st at <strong>the</strong> very latest.<br />
Quarterly Brainteaser<br />
Solution to <strong>the</strong><br />
December 2004 brainteaser:<br />
Last time we asked our esteemed<br />
readers to sort out <strong>the</strong> off-duty activities<br />
among <strong>the</strong> three nationalities on<br />
board <strong>the</strong> ship Bow Tricky, through a<br />
number of more or less enlightening<br />
pieces of in<strong>for</strong>mation. To cut a not too<br />
long story even shorter, <strong>the</strong> table<br />
below shows <strong>the</strong> pastime allocation of<br />
<strong>the</strong> crewmembers.<br />
Hence: Two Filipinos play rock'n roll,<br />
four Greeks sing karaoke, and three<br />
Norwegians play basketball.<br />
I'm happy to see that we received no<br />
less than twelve suggested solutions<br />
this time, with varying degree of detail<br />
but all coming to <strong>the</strong> same correct conclusion.<br />
We have drawn <strong>the</strong> winner, and<br />
<strong>the</strong> lucky "brainchamp" this time is<br />
