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.
