tons, is $50 feet long; so feet beam
and 1862 feet deep She Will make
Rotterdam her home port.
There was the usual post-Iaunching
luncheon al a local hotel at which
speeches appropriate TO the occasion
were made.
The "Antwerpen" is one Of a fleet
Of oil tankers which the Newport
News Shipbuilding and Dry Dock
Company is building for the Standard
on Company.
These vessels are by far the largest
tankers yet constructed in the United
States, and are only slightly exceeded
in size by a few tankers in the entire
world Some idea OF their enormous
capacity may be obtained from the
faef that eaeh vessel has a tank ca
pactty for over 5000. 600 gallons OF
cargo oil They are of the fish deck
type, with total length of ST. feet
and beam OF SIS feet. a depth TO shell
ter deck OF IS feet and will have
deadweiEht carrying capacity when
loaded to a draft of slightly over 81
feet, Of nearly 1900 tons. In COM
mon with modern practices In tank
ships, the propcling machinery is To-
Gated aft. but they differ from the
usual type in that hey are twin screw
/ vessels Each vessel has ten main
oil tanks divided by an oil-tight CEN
teriine hulkhead into two compart-
ments each, thus making twenty COM
! partments, In addition there are on
, each side Of the vessel in the wings
between main and upper decks. six
| Is a total of thirty-two oil compart-
ments, the combined capacity of
which makes up the grand total of
5, 900, 600 gallons. These tanks are so
subdivided by coferdams and pump
| rooms that three entirely different
grades of oil may be carried at the
same time without possibility OF mix
! ing. In all there re four complete
atwartshtp. cofferdams for the pur-
pose OF suhdviding the oil tanks to
separate the latter from the general
tdiE o NRltt anu tiiF runners, ana 10
separate the boiler-room from the
bunkers. In adsttion to the tanks for
the cargo oil the main bunkers are
arranged so as TO carry either fuel oil
or coal. and there is also a deep tank
forward divided into two compart-
ments in which fuel oil may be car
ried a total tank capacity for AIS. 900
gallons of fuel oil being provided,
which is the equivalent of about /, 500
tons. Coal bunkers are also provided
for total capacity OF 2,20o tons, 80
that whether using oil or coal for
fuel the vessel has capacity enough for
at least thirty-f1ve days steamng at
full speed at sea, which will allow II to
steam 5000 miles without refueling,
The "Antwerpen" is provided with

and are so equipped as 10 use either
coal or oil for fuel Each engine has
Its own auxiliaries, thus providing ad
ditional insurance against a possible
machinery. A large donkey boiler is
fitted for supplying necessary steam
for port use.
The appliances for handling cargo
oil are necessarily quite elaborate.
For this purpose there are two large
pumps Installed in separate pump
roof located near the middle Of the
oil tanks. These pumps are connect
ed to the several Oil tanks by two
lines of piping for each of the three
subdivisions into which the cargo oil
may be graded, and so connected that
two kinds of oil may be loaded or dis
charged simultaneously. Valves are
80 fitted as TO enable either pump to
draw from any compartment and de-
liver into any of the other compart-
ments, and also that either or both
pumps can discharge separately to
either or both sides Of the vessel. APP
