of major advantages to the builder
and the operator.
One advantage for the builder
being that since there are no inter-
sections between the transverse and
longitudinal members, a great deal
of automated welding can be used
and welds mechanically checked.
For the owner, the Epoch Mark II
design offers cargo flexibility, the
eligibility of trading to the U.S., and
improved maintenance, since her
tanks have a flush interior.
The Salamina has an overall
length of 600 feet, breadth of 105
feet, and design draft of 36 feet. She
is powered by a single Hitachi Zosen-
MAN B&W slow-speed 6S50MC die-
sel engine with a maximum con-
tinuous output of 9,200 hp at 106
rpm, producing a maximum trial
speed of just over 15 knots.
SOLIDARNOSC
Burmeister & Wain
Circle 79 on Reader Service Card
The first of a series of six Panamax
bulk carriers, Solidarnosc, for the
Polish Steamship Company was
delivered by Danish builder
Burmeister & Wain (B&W) during
the past year.
Based on B&W's BCT70 design,
the Solidarnosc has a length of 750
feet, molded breadth of 106 feet, and
design draft of 41 feet. Propulsion is
provided by one MAN-B&W cross-
head diesel engine of the five-cylin-
der, direct-reversible, single-acting,
two-stroke, constant-pressure tur-
bocharged 5S60MC, achieving a
speed of 15.2 knots when the main
engine is developing 9,800 bhp. Aux-
iliary engines consist of three die-
sels, type MAN-B&W 5L23/30 or
equivalent, each directly coupled to
an alternator, 550 kw, 720 rpm, 3 by
440 V, 60 Hz. There is also an
emergency diesel generator of ap-
proximately 100 kw.
The BCT70 is a flexible type and
can be delivered either as bulk car-
rier, product carrier or OBO-car-
rier. The vessel's design is such that
the owner can postpone the decision
as to whether it should be bulk car-
rier or OBO-carrier until the con-
struction stage is reached when spe-
cialized equipment—auxiliary en-
gines, pumps, etc.—must be ordered.
It is a double hull vessel with all
structural reinforcement between
the inner and outer hull. As a conse-
quence, the holds are completely free
of sharp edges and, therefore, easy
to clean and maintain.
USNS THOMPSON
Trinity Marine Group
Circle 77 on Reader Service Card
The first Navy oceanographic ship
of a Halter Marine design, the Tho-
mas G. Thompson (AGOR-23), was
delivered during the past year, Trin-
ity Industries, Inc.'s Halter Marine,
Inc., New Orleans, La. Operated by
the University of Washington under
the University National Oceano-
graphic Laboratory System
(UNOLS) sponsored by the office of
the Chief of Naval Research, U.S.
Navy, the Thompson serves as a
general purpose, all-season, oceano-
graphic ship in coastal and deep
ocean waters.
Typical scientific missions will
include physical, chemical and bio-
logical oceanography, multi-disci-
pline environmental investigations,
ocean engineering, marine acous-
tics, marine geology and geophysics,
and survey tasks such as bathym-
etry and magnetometry.
Based on a Halter design selected
in national competition, the AGOR-
23 has a diesel electric propulsion
system with three 715-kw and three
1,500-kw diesel generators inte-
grated to provide power for propul-
sion and ship service electrical sys-
tems. The propulsion package con-
sists of three Caterpillar diesels with
KATO generators and GE propul-
sion motors.
The ship is equipped with a dy-
namic positioning system which pro-
vides automated precision track-line
and station-keeping capability. The
system uses data from a global posi-
tioning system, an acoustic vertical
reference system, the gyrocompass,
and a wind sensor system to control
the ship.
The Thomas G. Thompson is 274
feet in length, with a 52.5-foot beam,
and a 18.5-foot draft. Full load dis-
placement is 3,250 tons.
USNS VICTORIOUS
McDermott Shipyards
Circle 89 on Reader Service Card
The first of a new class of Navy
SWATH ocean surveillance ships,
the 232-foot USNS Victorious (T-
AGOS-19) emerged from
McDermott's Morgan City, La., ship-
yard. With a wide open deck
mounted 25 feet above the water on
twin hulls, the Navy's first in-ser-
vice SWATH (Small Waterplane
Area Twin-Hulled) vessel is uncom-
mon in appearance but refined in its
unique abilities.
The Victorious has a 94-foot beam
and a 24-foot 9-inch draft. The small
waterplane design, with its reduced
buoyant forces in the area if wave
action, was chosen specifically for
its ability to provide a smooth ride in
high sea states.
Among the additional benefits to
the SWATH design is a large main
deck area suitable for multiple ap-
plications.
The 3,380-long-ton Victorious is
diesel-electric powered with the
main gensets, consisting of four Cat-
erpillar 3512 diesel with Kato gen-
erators, located in the upper hull.
GE electric propulsion motors, rated
at 1,600 shp, drive five-bladed pro-
pellers at the stern of each lower
hull. Lister Chain & Forge supplied
the vessel's anchor chain.
HITACHI ZOSEN DELIVERS A NEW ERA
IN PRODUCT OIL CARRIER DESIGN.
Announcing delivery of the first of the EPOCH MARK II series.
Hitachi Zosen has delivered the first
ship in their EPOCH MARK II series, in
addition to having three more ships
currently under construction.
All four ships utilize Hitachi Zosen's
revolutionary EPOCH MARK II concept,
which incorporates a unique
unidirectional girder system
combined with a complete
double hull structure.
While a ship's hull is
customarily designed with
a grillage of longitudinal
and transverse members
for strength, this system
uses only longitudinal
members in a double hull to provide
sufficient strength.
This unidirectional girder system results
in unprecedented structural simplicity and
completely flush surfaced cargo tank
interior. MARK II product oil
carriers provide unrivaled
advantages in performance
over more conventional
designs.
The EPOCH MARK II
series is available in 40 and
60 thousand dwt designs and
Hitachi Zosen has
obtained many patents
worldwide.
The Superior Performance of the EPOCH MARK n Series:
Tank configuration
Cargo/ballast segregation
Unloading efficiency
Cargo tank cleaning
Cargo tank heating
cargo tank coating
hull construction
stranding & collision
