Phoenix Oil Refiner offers.
Oil doesn't wear out.
It just gets dirty. In fact, oil refiners
themselves will tell you that if oil can
be kept clean, its efficiency as a lubri-
cant actually increases with time. So
if you could keep oil clean, really
clean, you'd drastically cut down on
oil changes and oil costs. And you'd
extend engine life as a big bonus.
So how clean does the
Phoenix Oil Refiner get oil?
It removes 99.4% of all impurities...
dust, dirt, sludge, water, acid and
sulphur ash. It actually reconditions
the oil. In fact. Phoenix Oil Refiner-
equipped trucks have run over
500,000 miles without an oil change!
Best of all,
the Phoenix Oil Refiner
is available novft
It's available in seven sizes for just
about any application you can name.
Write or call us (collect) for more
information or the name of your near-
est sales representative. Every day
you wait is costing you money.

Halter Marine Delivers
The Point Liberty To Point Express
Halter Marine, Inc., of New
Orleans, La., recently delivered
the Point Liberty, the third of
four 191-foot tug/supply boats
to Point Express, Ltd., of Mor-
gan City, La.
The Point Liberty is 191-feet
long with a 40-foot beam and a
14-foot depth. She is powered by
two EMD 16-645C diesel engines
developing 1,950 hp each at 900
rpm. They drive two, 90-inch-
diameter four-bladed propellers
through Lufkin RHS 2120 re-
verse/reduction gears with a ra-
tio of 3.0:1.
The vessel's six Smatco tanks
each carry 1,000 cubic feet of
bulk mud and four additional
tanks carry 1,344 barrels of liq-
uid mud. Dry mud is moved
through the system by a Gardner
Denver WCG air compressor and
liquid muds are pumped by Mis-
sion Magnum pumps.
Some of the Point Liberty's
other capacities are: 61,000 gal-
lons of fuel oil; 1,824 gallons lube
oil; 165,400 gallons ballast water;
and, 16,888 gallons of fresh wa-
ter. Her aft deck has nearly 4,000
square feet of cargo space.
There are two Westinghouse
equipped control stations aboard
and a 56-point engine alarm sys-
• tem provided by EMI. The hy-
draulic steering system was man-
ufactured by SSI. The vessel's
maneuverability is enhanced by a
Bird-Johnson model 20 bow-
thruster driven by a Detroit Die-
sel 8V71 diesel engine through
Capitol reverse/reduction gears.
The main switchboard and distri-
bution panels were built by Con-
tinental Electric.
Auxiliary power is supplied by
two Detroit Diesel 8V71-N die-
sel engines generating 125 kw.
Two Quincy model D325 air com-
pressors provide compressed air
for diesel engine starting, the

pneumatic control system, air
whistle, sea chest, and ship

Aurora pumps service bilge,
ballast, fuel transfer, and the on-
ship fire-fighting system while
Viking pumps handle oily bilge
and fuel oil standby. The fuel
oil separator model OTB-2-OO-
066 was manufactured by West-
falia and supplied by Marine
Engineering, Inc., of Belle Chase,
La. The sanitary water system
contains a Deming pressure set
with a vertical 82 gallon tank.
Water closets drain into a Micro-
phor MC-200 sewage treatment
system.
