Moss Point Marine, Inc. of Moss
Point, Miss., announced the deliv-
ery recently of two 180-foot-class
multipurpose supply vessels to be
operated by Golden Gulf Marine

her sister M V Golden Moon are
the second and third such vessels
of a 12-boat package by Moss

the Gulf of Mexico.
The vessels each have molded
beams of 40 feet and molded
depths of 14 feet. Their onboard
capacities (each) include 57,000
gallons of fuel, 11,200 gallons of
potable water, 1,540 barrels liq-
uid mud storage and 3,600-cubic-
foot dry mud volume. The vessels,
registered at under 300 tons, can
carry 550 tons of deck load ca-
pacity.
The Golden Girl and Golden
Moon are powered bv twin 12-
cylinder EMD 645E-2 diesels re-
built by National Marine, cou-
pled to Falk marine gears on a
3:1 ratio. Shipboard electrical
power is provided by a set of two
125-kw GM 6V71 turbocharged
generators.
In the pilothouses, a complete
electronics package includes two
Sailor YHFs, one all band re-
ceiver, a Drake SSB radio, a
Necode, two Furuno radars, a
Texas Instruments 9900 Loran C,
an Epsco recording fathometer
and one loud hailer.
The first vessel for Golden Gulf
Marine, the Golden Gulf, was de-
livered by Moss Point Marine in
mid-summer (See MR 'EN, Sep-
tember 1, 1981, page 52), with
the final boat in the 12-vessel
package scheduled for delivery in
February 1983.
MarAd Approves Title XI
Refinancing Guarantee
For 20 River Barges
The Maritime Administration
has approved in principle an ap-
plication from Shearson River
Barge Associates I, New York,
N.Y., for a Title XI guarantee
to aid in refinancing twenty 195-
foot river barges.
The barges, five built by Cargo
Carriers, Inc., and 15 by Nash-
ville (Tenn.) Bridge Co., were
delivered in 1979. The applicant
indicated the barges' main em-
ployment will be in the carriage
of grain, but that they may also
be used for other dry-bulk car-
goes, such as coal. The approved
guarantee is for $4,141,000, or up
to 87'2 percent of the depreci-
ated actual cost of the barges.

Two GM Detroit Diesel 6-71M engines power the oil recovery vessel Marlimpia.
The oil recovery system was designed by Centrifugal Systems, Inc., of Houston,
Texas, for use on Lake Maracaibo, Venezuela.
Monark Boat Delivers Oil Recovery
Vessel For Use On Lake Maracaibo
A new oil recovery vessel was
recently delivered to the owners,
The Lake Committee, Lake Mara-
caibo, La Salina, Venezuela. De-
signed by Centrifugal Systems,
Inc. of Houston, Texas, and built
by Monark Boat Company, Mon-
ticello, Ark., the Marlimpia is a
catamaran type, self-propelled,
28-ton aluminum vessel.
The oil-recovery system, exclu-
sively designed and built by Cen-
trifugal Systems, Inc., consists of
four 12-inch-diameter Petro Mops
with the puller-wringer and re-
turn pulley assemblies ; the Weir
recovery system ; dispersant
agent with monitors; and 500
linear feet of 18-inch oil contain-
ment boom.
The Petro Mop system used on
the Marlimpia is able to recover
a maximum of 600 barrels of
spilled oil per hour and the Weir
System, 250 barrels per hour. The
vessel is 48 feet length overall,
with 17 feet :is inches width over-
all. The tunnel between the hulls
is more than 6 feet.
Propelled by two Detroit Diesel
6-71M's, the Marlimpia easily
cruised at 20 knots down the Mis-
sissippi River on her maiden voy-
age to New Orleans for shipment.
Daniel F. Young, Inc. arranged
the lift and deck shipment to
Venezuela.
The GM 3-71 72-kw generator
set provides electric power to
the auxiliary machinery and re-
claimed oil tanks' heating system.
The heating system allows the
viscosity of the reclaimed oil to
be lowered before being offloaded.
The auxiliary machinery in-
cludes electrohydraulic systems
for powering the puller-wringer,
Weir, Petro Mop return system,
and a telescopic hydraulic Hap-
610 crane of 4,000 pounds at 10-
foot-reach capacity located mid-
ship. The crane was installed for
deploying and retrieving the oil
containment boom. However, a
hydraulic crane aboard a stable
work platform, such as this ves-
sel, has many other uses in an
emergency situation in the off-
shore energy industry.
The Marlimpia has the equip-
ment to fight fires on offshore
platforms and other vessels. Its
two Elkhart 21L>-inch fire moni-
tors include fire-foam eductors
with a maximum reach of 140
feet. The fire monitors also serve
as dispersant applicators, apply-
ing Exxon Chemical Company's
Corexit 9527 oil dispersant as
permitted on Lake Maracaibo.
The dispersant is blended with
sea water by a variable propor-
tional injector pump before being
applied to the oil slick. Dispers-
ant application rates can be var-
ied from near zero to as much
as 15 U.S. gallons per acre. The
system automatically sets the cor-
rect amount of sea water for the
selected dispersant application
rate and vessel speed.
Further, the vessel is equipped
with a dedicated system to apply
